It has been found only in Panamá and Costa Rica.[1] It is named for the botanist William Ralph Maxon. Erigeron maxonii is a perennial subshrub with a woody stem up to 50 cm (20 inches) tall, producing a woody taproot. Stems are sometimes erect (standing straight up), sometimes reclining on the ground or leaning on other vegetation. The plant produces flower heads on long, thin stalks. Each head contains 40-115 white, pink, or red ray florets surrounding numerous yellow disc florets.[1][2][3]References1. ^1 2 Nesom, G.L. and J.F. Pruski. 2011.
