Gonzalezia (plant)

Gonzalezia is a genus of flowering plants belonging to the family Asteraceae.

Its native range is northern and western Mexico.

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, 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, Bahiopsis , Calanticaria , Davilanthus , Dendroviguiera , Gonzalezia , Heiseria , Heliomeris , Hymenostephium , Sidneya and Viguiera.

The genus name of Gonzalezia is in honour of María del Socorro González Elizondo (b. 1953), a Mexican plant taxonomist with a focus on Cyperaceae. It was first described and published by botanists Edward E. Schilling and José Luis Panero in Bot. J. Linn. Soc. Vol.167 on page 326 in 2011.
