Heliomeris is a genus of flowering plants in the family Asteraceae,Nuttall, Thomas. 1848. Proceedings of the Academy of Natural Sciences of Philadelphia 4(1): 19 (entirely in English)Tropicos, Heliomeris Nutt. 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.Yates, W. F., Jr. and C. B. Heiser Jr. 1979. Synopsis of Heliomeris (Compositae). Proceedings of the Indiana Academy of Science 88: 364-372.
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.Flora North America, Heliomeris Nutt.
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 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 .
