lucrate or near the head. Central head of plant generally twice 
as large as the others and on an erect and leafy peduncle. 
Stems with many proliferous branches below and 2- y long ast 
naked, ending in a cluster of 1-3 flowers, and either simple o 
short- branched, the heads with disk about 6” high and 6-8” 
wide. Rays 2” wide and 8-10” long, bright-pink. Scales with 
broad, lacerate and ee e margins, acute. Pappus of ray 
about as long as width of akene, that of the disk as long as the 
flowers and plumose, the teeth being longer than the width 
of the hair, sete often forked at base. Plants conspicuous by 
being nearly green and proliferous with long rays, but there 
are intergrades. Common throughout the Duchesne valley, 
tah in exposed and gravelly places in.the Lower Temperate — 
life zone, in May. My material gathered mostly on May 20 
1908 : 
Townsendia incana is correctly described by Torrey and 
_the width of the akene, and that of the disk as long as the 
flowers, with sete mostly simple and teeth shorter than the 
width of the scale or hair. The type and variety differ con- 
spicuouslv = baee have the same range and intergtade freely. 
Partheni pinum var. ligulatum n. var. Ligule oval to 
round, At6othed at tip, 1-2” long, rough-pubescent below, 
rigid. Pappus adnate to the very thick corolla tube, green, 
lacerate, triangular, about as lone as the tube. _ Akenes hoary, 
jointed, 2-4” long, avd straight. Leaves spatulate-oblance- 
olate. Plants very ¢ losely resemble’ Erio ogonum acaule and 
grow in similar situations on nearly bare clayey and gravelly 
knolls on ridges at 6000° alt. forming dense mats 6-12’ wide, 
with thick and branched roots, habit also i Mears acaulis.
