Heliomeris Explained

Heliomeris is a genus of flowering plants in the family Asteraceae,^{[1] [2]} known generally as false goldeneyes.

They are native to the western United States and northern Mexico. One species, H. obscura, is separated from the others, endemic to a remote area on the border between the Mexican states of Puebla and Oaxaca.^[3]

These are annual and perennial herbs producing sunflower-like radiate flower heads. They are distinguished from related genera by the achenes, which are glabrous and lack a pappus, and by the involucre, which consists of only 2 series of bracts.^[4]

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 other nine genera: Aldama, Bahiopsis, Calanticaria, Davilanthus, Dendroviguiera, Gonzalezia, Heiseria, Heliomeris, Hymenostephium, Sidneya and Viguiera .^{[5] [6]}
