Aldama is a genus of flowering plants in the family Asteraceae. The native range of this genus is tropical & sub-tropical America. The genus was originally described to include one (later two) species of subtribe Helianthinae that were characterized by having pales that tightly enclosed the cypselae ( achenes) (see Feddema, 1971). [2]
It was first published and described in P.de La Llave & J.M.de Lexarza, Nov. Veg. Descr. 1: 14 in 1824. [1]
Aldama is currently, characterized by having a perennial herbaceous habit, a pappus usually of awns and scales, and a multi-seriate involucre.
Botanists Schilling & Panero in 2002 and 2011, studied the subtribe Helianthinae based on molecular sequences of nuclear ITS, ETS, and cpDNA, coming to a conclusion that that the genus Viguiera Kunth, did not constitute a monophyletic group. Among their conclusions they proposed to reclassify the genus, dividing and relocating its species in at least eleven genera: Aldama La Llave, Bahiopsis Kellogg, Calanticaria (B.L. Rob. & Greenm.) E.E. Schill. & Panero, Davilanthus E.E. Schill. & Panero, Dendroviguiera E.E. Schill. & Panero, Gonzalezia E.E. Schill. & Panero, Heiseria E.E. Schill. & Panero, Heliomeris Nutt., Hymenostephium Benth., Sidneya E.E. Schill. & Panero and Viguiera Kunth. [3] [4] So Aldama has been expanded to include a total of 115-118 species. [4] [5]
Distribution
It is native to (countries of): Argentina, Belize, Bolivia, Brazil, northern and central Chile, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Paraguay, Peru, Uruguay, United States (in the states of Arizona, New Mexico and Texas) and Venezuela. [1]
