Su única colecta conocida son los ejemplares tipo de 1891, sin flores, procedentes de una localidad no especificada del municipio Culiacán. En 2023 se ubicaron nuevas poblaciones en las proximidades de la ciudad de Culiacán, por lo que aquí se presenta su descripción enmendada, se ilustra por primera vez y se actualiza su distribución conocida. Adicionalmente, se presenta una clave para identificar las especies de Eugenia en Sinaloa.  Métodos: Se realizaron exploraciones, colectas botánicas y toma de fotografías de 2023 a 2025. Se consultaron ejemplares de herbarios para localizar posibles colectas erróneamente identificadas. A partir de material localizado, se realizaron: 1) descripción actualizada de la especie, 2) ilustración científica por primera vez, 3) láminas fotográficas, 4) propuesta de estado de conservación actualizado y 5) clave de identificación para las especies de Eugenia en Sinaloa.  Resultados clave: Eugenia inconspicua es endémica del centro de Sinaloa, crece en suelos de origen volcánico con selva baja caducifolia, selva espinosa y su Extensión de Presencia es 584.042 km2. Presenta afinidad morfológica con Eugenia crenularis, de la que se diferencia por el tipo de indumento, forma del margen de la hoja y distribución geográfica. Localmente se le conoce como arrayán negro y sus frutos con comestibles.  Conclusiones: La presente investigación aporta certeza sobre la identidad y distribución de Eugenia inconspicua, identificando las áreas prioritarias para su conservación. Considerando la nueva distribución conocida, se propone cambiar su estado de conservación a Amenazada (EN). Por otro lado, el género aun requiere revisión en Sinaloa; se estiman de cinco a siete especies, con dos endémicas (Eugenia inconspicua y Eugenia sinaloae) y dos cuya presencia es debatible (Eugenia crenularis y Eugenia salamensis).]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Background and Aims: Eugenia inconspicua is a shrub endemic to Sinaloa, Mexico, listed as Critically Endangered by the IUCN Red List. Its only known collection are the type specimens from 1891, without flowers, from an unspecified location in the municipality of Culiacán. In 2023, new populations were found in the vicinity of the city of Culiacán, so here we present its emended description, illustrate it for the first time, and update its known distribution. Additionally, notes on Eugenia species in Sinaloa are presented.  Methods: Explorations, botanical collections, and field photographs were made from 2023 to 2025. Herbarium specimens were consulted to locate possibly misidentified collections. Based on the located material, the following was done: 1) an updated description of the species, 2) a scientific illustration for the first time, 3) photographic plates, 4) a proposal for an updated conservation status, and 5) an identification key for Eugenia species in Sinaloa.  Key results: Eugenia inconspicua is endemic to central Sinaloa, growing in volcanic soils with tropical deciduous and thorn forest, and an Extent of Occurrence of 584.042 km2. It is morphologically similar to Eugenia crenularis, from which it differs in the type of indumentum, leaf margin shape, and geographical distribution.  Conclusions: This research provides certainty about the identity and distribution of Eugenia inconspicua, identifying priority areas for its conservation. Considering the new known distribution, it is proposed to change its conservation status to Endangered (EN). Furthermore, the genus still requires review in Sinaloa; five to seven species are estimated, with two of them endemic (Eugenia inconspicua and Eugenia sinaloae) and two whose presence is debatable (Eugenia crenularis and Eugenia salamensis).]]></p></abstract>
