Chamaechaenactis scaposa
(Eastwood Plant or Fullstem) Semi-desert, foothills.
Woodlands, openings. Spring, summer. Chamaechaenactis scaposa is a rare find in its limited range of the Four Corners states. It is a long-lived perennial, growing no taller than about 4 inches and spreading in mats 4-10 inches across. The entire plant is hairy. Alice Eastwood discovered this plant for science near Grand Junction in May of 1891. She named it Chaenactis scaposa, but in 1906 Rydberg placed it in a new genus, Chamaechaenactis, because he realized that it differed from the Chaenactis genus in being scapose (leafless stem), having round leaves which are entire, and pappus scales without a mid-rib. "Chamae" is from the Greek "Chamai", "on the ground" and is used to mean "dwarf" or "creeping". |
