Sobre la identidad de Mimosa margaritae y M. tricephala en Baja California, México

[摘要] Since its initial discovery,Mimosa margaritaehas been known only from the type, a non-reproductive specimen collected 125 years ago on Margarita Island, off the Pacific coast of Baja California Peninsula. Other specimens from the same Peninsula were mistakenly identified asM. margaritae , but are in factMimosa tricephala , one of the closest relatives ofM. margaritae . During recent expeditions to the island,M. margaritaewas rediscovered. Here, we provide the first description of the flowers and fruits of this species. The taxonomic status of the southern peninsular endemicM. lagunensisis also discussed; we conclude that it should be treated as a variety ofM. tricephala,and provide a new combination,M. tricephalavar.lagunensis .
