PEREZ-CHAVEZ, Itzel; SOTUYO, Solange y TORRES-COLIN, Leticia. Pollen morphology in Lonchocarpus section Punctati (Fabaceae: Papilionoideae). Rev. Mex. Biodiv. [online]. 2022, vol.93, e934152. Epub 05-Jun-2023. ISSN 2007-8706. https://doi.org/10.22201/ib.20078706e.2022.93.4152.
Pollen morphology from 14 species of Lonchocarpus section Punctati (L. adamsii, L. angusticarpus, L. benthamianus, L. berriozabalensis, L. cochleatus, L. glaucifolius, L. longipedicellatus, L. longipes, L. longistylus, L. major, L. michelianus, L. punctatus, L. tenorioi and L. vallicola). The pollen grains were acetolised and prepared for scanning electron microscope. The results provide information for the first time on the pollen morphology in this section. Pollen grains are small, with different forms, such as prolate spheroidal, subprolate, oblate spheroidal, to suboblate. Exine sculpturing, in most of the species, is rugulate. Although, in some others, it is foveolate, microreticulate or verrucate. All species recorded tricolporate apertures with a granular membrane.
