On the identity of Mimosa margaritae and M. tricephala in Baja California, Mexico
Since its initial discovery, Mimosa margaritae has 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 as M. margaritae, but are...

| description | Since its initial discovery, Mimosa margaritae has 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 as M. margaritae, but are in fact Mimosa tricephala, one of the closest relatives of M. margaritae. During recent expeditions to the island, M. margaritae was rediscovered. Here, we provide the first description of the flowers and fruits of this species. The taxonomic status of the southern peninsular endemic M. lagunensis is also discussed; we conclude that it should be treated as a variety of M. tricephala, and provide a new combination, M. tricephala var. lagunensis. |

Desde su descubrimiento, Mimosa margaritae había sido conocida solo del ejemplar tipo, un espécimen estéril, colectado hace 125 años en la isla Margarita, cercana a la costa Pacífica de la Península de Baja California. Otros ejemplares colectados en territorio peninsular habían sido determinados erróneamente como M. margaritae pero en realidad corresponden a M. tricephala, uno de los taxa más cercanos de M. margaritae. Durante exploraciones recientes a la isla, M. margaritae ha sido redescubierta. En este trabajo se describen por primera vez las flores y los frutos de esta especie. Adicionalmente, se discute el estatus taxonómico de M. lagunensis, endémica del sur peninsular, se concluye que debe ser tratada como una variedad de M. tricephala y aquí se presenta una combinación nueva, M. tricephala var. lagunensis.
