Abstract

A new subfruticose Eriogonum (Polygonaceae) is described as E. pelinophilum, from specimens obtained near Hotchkiss, Delta Co., Colorado. A member of the subgenus Eucycla, the new species is most closely related to E. contortum Small ex Rydb., but differs in having cream-colored flowers instead of bright yellow flowers. The two species also differ in that E. pelinophilum has narrowly turbinate involucres which are longer than those of E. contortum and larger flowers and achenes. The new species is apparently restricted to gumbo clay hills west of Hotchkiss.
