Abstract:

Background:

The Hinton family comprises three generations of plant collectors that have made an important contribution to the knowledge of the flora of Mexico. They have collected in 13 Mexican states and have provided material for the description of 6 genera, 621 species and 51 infraspecific taxa new to science.

Question:

What is the contribution of the collections of the Hintons to our knowledge of the flora of Mexico? Where was their main collecting effort and how many species have been recorded?

Species study:

Vascular plants.

Study site:

Mexico.

Method:

Different national and foreign databases were consulted and a list of species collected by the Hintons was obtained. The records were reviewed to eliminate synonymy and a complete list of species and their distribution by states was compiled.

Results:

A total of 28,947 records were obtained and 25,717 of them were identified to species level. In addition to the family's collection, the herbaria with the largest number of records are LL-TEX, K, IEB, and MEXU. The records come from about 1,654 different collecting localities throughout Mexico and account for 5,730 species, 1,573 genera, and 233 families.

Conclusions:

Many of the specimens collected by the Hintons come from areas that are still underexplored today. The contribution of the Hinton family to the knowledge of the flora of Mexico represents an important legacy and their collections constitute an enduring source of information for people interested in the flora of Mexico.

In 1972, Jaime Hinton and Jerzy Rzedowski published the biography of George Boole Hinton (1882-1943, Figure 1), a botanical collector born in London, England (a spanish version of this contribution was published in 1975). These authors point out that in 1911 he arrived in Mexico and after working for many years as a metallurgist, at the age of 54 he retired from mining to devote himself to collecting botanical specimens. During ten years of intense activity of fieldwork, Hinton managed to make a collection of just over 16,000 numbers from difficult and unexplored localities in the states of Guerrero, México, and Michoacán. In his biography, Hinton and Rzedowski relate the difficulties encountered and the effort required to amass one of the best collections of regions of Mexico that to this day persist as scientifically underexplored due to the ruggedness of the topography and to social and political unrest.

Figure 1 From left to right: George Boole Hinton, James Hinton, and George Sebastian Hinton.

Fondness for collecting botanical specimens was also acquired by George’s son James (1915-2006, Figure 1), who in July 1937 joined his father for fieldwork in the state of Guerrero. He soon became one of the main collectors of Mexican plants; after his father's death he continued collecting specimens in other parts of the country, especially Coahuila, Nuevo León, Oaxaca, and Tamaulipas. Table 1 indicates the number of collections carried out in these states based on the collections of George and James Hinton. Later, when James was living in the state of Nuevo León, his son George Sebastian (Figure 1) began accompanying James on his botanical explorations. Since then, George S. has continued this tradition, building up one of the largest personal scientific collection documenting the flora of northeastern Mexico, with the discovery of many new taxa. Based on all these collections, 6 genera and 621 new species were discovered.

This paper aims to document and analyze the entire Hinton collection in order to evaluate its contribution to our knowledge of the flora of Mexico. As can be seen in Table 1, there are three main periods when the Hinton family (the grandfather, the son, and the grandson) carried out fieldwork, mostly restricted to specific regions in the country. The role of each set of specimens is evaluated and their contribution to the knowledge of the regional and national flora is discussed. Finally, a list of the accepted species and the collection numbers documenting their occurrence is provided. The material that forms the basis of the descriptions of the new taxa is highlighted.

A short story of the collecting effort of the Hinton family. George B. Hinton started fieldwork on October 11^th, 1931. His first plant collected was Elaphoglossum erinaceum (Fée) T. Moore in the La Labor, District (now Municipality) of Temascaltepec, state of México. His last collection was number 16,314 on January 31, 1943 from the Los Hornos, District of Temascaltepec. In that period he was assisted by Luis Martínez and Gerónimo García, natives of the region. On July 23, 1937, his son James left his studies in Canada to help his father full time in his collecting enterprise. James started his collecting in the state of Guerrero. This first period accounts for about 16,000 collecting numbers and resulted in the description of 471 new taxa.

After his father´s death in 1944 James collected intermittently in Coahuila, Nuevo León, and Morelos. In 1964 he started collecting again in the alpine areas of southeastern Nuevo León and adjacent Coahuila. He also collected in alpine regions of Tamaulipas and later in Oaxaca. James continued the numbering of his father and his last collecting was recorded on October 14, 1995 (GBH 26,855). During this time, he collected 7,227 numbers, which included 116 new taxa.

James’ son George Sebastian started collecting plants in 1989; with his father he made 1,183 collections and 6,712 on his own. After his father’s death, he has continued to conduct fieldwork, mostly in the states of Coahuila and Nuevo León, and has also continued the numbering started by his grandfather. One genus and 34 new taxa have been described from these collections. To date, the Hintons’ collection catalogues almost 29,000 collection numbers.

Materials and methods

The list of species collected by the Hinton family was obtained mainly from the database created and administered by George S. Hinton for their own collections. The records contained in the database were complemented and compared with two other important databases, the National Biodiversity Information System (SNIB-REMIB) maintained by the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (CONABIO), and the digital repository of the National Herbarium of Mexico (MEXU-UNIBIO), maintained by the Instituto de Biología, Universidad Nacional Autónoma de México (UNAM).

Once the three databases were fused, a list of species and the collection numbers supporting each scientific name was obtained. The list of names was compared with the national checklist published by ^{Villaseñor
(2016)} and with the catalogs of Tropicos (http://www.tropicos.org) and The International Plant Names Index (http://www.ipni.org/ now http://www.plantsoftheworldonline.org/) in order to cite the most currently accepted name and to eliminate the names considered synonyms. The entire list of species is provided in the Appendix 1. The Appendix 2 (see Supplementary Material) includes the same list but ordered by collecting numbers. When a collection number represents the voucher from which a new taxon was described, it is indicated with the word TYPUS.

Results

The database built by George S. Hinton summarizes all the collection effort carried out during three generations of his family (Table 1). It accounts for 28,947 unique records collected from 1931 to 2018 (Appendix 1). This figure includes 25,717 records fully identified (to species level) and 3,229 unidentified. This latter figure includes 213 records with uncertain, unresolved names. Table 2 summarizes the current status of the records organized by main botanical groupings. The angiosperms constitute the best represented group, particularly the dicots (Magnoliopsida) with the largest number of records, followed by the monocots and the ferns. The database includes 26 additional records of non-vascular plants (Cryptogams).

Gymnosperms	192	175

The revision of the different databases (GBH, Hinton’s personal collection), SNIB, and UNIBIO) resulted in the combination of a total of 71,136 records that document the Hinton collections stored in more than 40 herbaria, either national or foreign. Table 3 indicates the number of specimens stored in the 10 herbaria with the largest number of records. Without considering the private collection (GBH), the herbaria with the most records (LL-TEX and K) have been involved in an important way in the identification of the material collected. An important account of the Fabaceae (Leguminosae) collected by G. B. Hinton and housed at K was published by ^{Rico-Arce et
al. (2008)}, who report 1,537 specimens including 85 genera and 415 species.

Figure 2 shows the localities where the plant specimens were collected. The western parts of the states of Guerrero, México, and Michoacán concentrate most of the collecting effort. Another important collecting site is located in southern Oaxaca, especially in the District of Miahuatlán where at least 15 new taxa were discovered (Table 1). The last important region where an intense collecting effort has been carried out is the southern half of the states of Coahuila and Nuevo León in northeastern Mexico. Tables 1 and 4 summarize the information about the collecting effort by each member of the Hinton family and the states where fieldwork has been carried out.

Table 4 shows the distribution of the records fully identified both by state and by number of collections (N = 25,717). The collecting effort was divided according to the three main periods of activities and people involved (I: George B. Hinton, George B. and James; II: James; III: James and George S., George S.). In each period the states collected are indicated as well as the number of records and species. It is likewise indicated the number of collections that constitute type material and represent new taxa to science.

The specimens collected come from all the five main biomes in Mexico (^{Villaseñor & Ortiz 2014}). Table 4 indicates the percentages of specimens collected in each biome by period. The main biomes where most collections come from are temperate forests, seasonally dry tropical forests, and xerophytic scrubs. The first collecting period was concentrated in the temperate and dry forests from western Mexico (Guerrero, México, and Michoacán); during the second the effort continued in the environments of the first but also concentrated in the xerophytic scrub of northeastern Mexico. The third has put much effort in collecting the dry environments of northeastern Mexico.

The database indicates that the specimens come from about 1,654 different collecting points, distributed in 16 out of 32 Mexican states (Figure 2, Table 5). The largest number of records come from the state of Nuevo León, accounting for 827 different collecting stations. The next largest number was made in the state of México, where many records were obtained although from a lesser number of stations. Table 5 shows the states where the specimens were obtained, the total number of records, and the number of different localities visited.

In total, the Hinton database records 5,730 species of vascular plants, distributed in 1,573 genera and 223 families. Table 5 indicates the best represented families and genera recorded in the database. It includes 6 genera and 621 species new to science described based on their collections; this figure does not include 65 additional taxa described with their collections at infrapecific level (subspecies or varieties). The six new genera are Cremastopus Paul G. Wilson (Cucurbitaceae, now a synonym of Cyclanthera), Geohintonia Glass & W.A. Fitz Maur. (Cactaceae), Hintonella Ames (Orchidaceae), Hintonia Bullock (Rubiaceae), Onocleopsis Ballard (Aspidiacae), and Symplococarpon Airy-Shaw (Theaceae).

Discussion

Among the most important botanical collectors of the 20th century, the Hinton family stands out for their great number of collections. Together they are among the 10 most prolific collectors in Mexico (Villaseñor, unpublished data) and undoubtedly rank first or second by their number of discoveries new to science. But more importantly, the regions where they collected remain inadequately explored, so that their collections represent for many taxa the only references that document their occurrence.

An important number of records remain in need of identification. A figure of 1,898 records lack placement among higher taxonomic groups (Table 2); in addition, 255 records are only identified to family level, and 863 records are identified to genus, still waiting their identification to species level. In addition, 213 records were left out because their determination was considered dubious, in need of corroboration.

Until now a figure of 6 genera and 621 new species have been described based on the Hintons’ collections (Table 4, Appendix 1). The current accepted taxonomy does recognize 460 of them as accepted species and 161 as synonyms. In addition, 65 new taxa at infraspecific level also have been described form their plant material (not included in this analysis). In particular, for the family Asteraceae, from a total of 3,825 specimens reviewed that constitute type material (Villaseñor, unpublished data), 188 new taxa have been described with specimens collected by them. This number places the Hintons in third place among those who have provided the most material for the description of new taxa, only after C. G. Pringle (397) and E. Palmer (272).

The collecting effort carried out by the Hintons represent an important contribution to state floras and the biomes included (Table 4). Compared with the figures provided by ^{Villaseñor (2016)}, the number of species recorded in the database for Guerrero includes 29.7 % of the state´s flora. Likewise, it includes 42.3 % of the flora of the state of México, 28 % of the flora of Michoacán, 23.5 % of the flora of Coahuila, and 53.6 % of the flora of Nuevo León. As mentioned before, many of the specimens collected by the Hintons in these states represent the only information available about the biology of the species recorded.

Several areas where the Hintons made efforts in collecting plants remain unexplored or floristically poorly known. For example, the Municipality of Temascaltepec in the state of Mexico was the area where George B. Hinton started his collecting effort; 2,061 species have been recorded there (Villaseñor, unpublished data) and the Hintons´ database records 1,039 (50.4 %) of these species. In contrast, 804 species are recorded for the Municipality of Luvianos, also in the state of Mexico, (Villaseñor, unpublished data), 618 (76.9 %) of which were collected by GB Hinton. Another region that stands out is southern Nuevo León, where most of the flora known there comes from the Hintons’ effort. For the entire state, 3,740 species have been reported (^{Villarreal-Quintanilla &
Estrada-Castillón 2008}, ^{Villaseñor
2016}); the Hintons’ effort has recorded 2,003 of these species, representing 53.6 % of the state’s flora. The Hintons are presently the most important collectors for the southern part of the state, and a first account of the state’s floristic diversity has been published (^{Hinton & Hinton 1995}).

The paper by ^{Rico-Arce et al.
(2008)} provides the opportunity to make a comparison between the information available at the Kew herbarium (K) and the records reported here. At K the authors indicate there are 1,537 records of Fabaceae (Leguminosae); this figure represents 18.3 % of the records for the Hintons housed at K (Table 3). Likewise, they represent about 63.6 % of the total records for the Fabaceae in the database described here. Finally, the 415 species of Fabaceae identified by the authors account for 72.8 % of the total species collected by the Hintons. ^{Rico-Arce et al.
(2008)} point out the important role that K had in the identification and housing of the collection generated by the Hinton family.

There is no doubt that the contribution of the Hinton family to the knowledge of the flora of Mexico constitutes an important legacy. Of individuals collectors that likewise have made important contributions to this effort, such as E. Palmer, C. G. Pringle, R. McVaugh, or J. Rzedowski, no other example like that of the Hintons exists in Mexico (and perhaps in other parts of the world) where at least three generations have been involved in continuing the important role of collecting botanical specimens. Their collections will for many years constitute an important source of information for all interested in the flora of Mexico.

An important number of specimens (11,804) from the Hintons’ collection can be reviewed at the Irekani web-page of the Instituto de Biología, Universidad Nacional Autónoma de México (http://unibio.unam.mx/irekani/?locale=es&proyecto=Irekani&column=2). The same set of pictures can also be observed at the search-by-species web-page of Tropicos maintained by the Missouri Botanical Garden.
