perfect specimens may have enabled those authors to place P. filipes under 
P. Taliscana with certainty. Dr. Gray, Fl. Cal. 1, p. 400, still considers 
them distinct.—Southern Arizona (539) In one specimen, I find three 
awns to the disk-flowers, which alternate with three scales, each half as 
long as the achenium. 
PecTis ANGUSTIFOLIA, Torr.—Low, much br vlleak: annual, 1-6’ high; 
leaves slightly connate and bristle-ciliate at base, bearing many oval glands, 
as also do the scales of the involucre; pappus in both ray- and disk-flowers 
a mere crown of small and somewhat dentate scales, or in some of the outer 
flowers of the head of one or two awns, when it is P. fastigiata, Gray (PI. 
Fendl. p. 62); achenia a little hairy—aA very much dwarfed form of the 
species, not over half an inch high, is in the collection, obtained by Dr. 
Loew, probably from New Mexico. Colorado (467). 
Pectis papposa, Gray.—‘‘Annual, glabrous, diffusely much branched, 
a span to a foot high, ‘lemon-scented’: leaves elongated-linear (2-3’ long, 
less than a line wide), furnished with very few bristles at base: heads 
slender-peduncled, scattered or corymbose, about 20-flowered: scales of the 
involucre 6-8-linear; rays, elongated, linear-oblong: pappus in the ray a 
scaly crown, in the disk of 15-20 capillary and very unequal barbellate 
bristles. Pl. Fendl. p. 62.” Not having access to satisfactory specimens 
of the above species, I have been obliged to appropriate the above complete 
description from FI. Cal. 1, p. 399.—Obtained by the Expedition in Arizona. 
Pectis TENELLA, DC.—Low and diffusely branched, smoothish; leaves 
1-2’ long, nearly a line wide; margins slightly revolute and bearing a few oval 
glands; rays twice (or nearly so) as long as the scales of the involucre, 
pappus (ray) a few small scales or rarely with anawn; disk-flowers about 10, 
two-thirds as long as the ray; pappus (disk) of about 15 very unequal and 
strongly upwardly barbed bristles; achenia sub-angled and hairy. My 
specimens do not at all accord with the description in DC. Prod. vol. vy, p. 
99, and I am unable to separate them clearly from the above description of 
P. papposa. Mr. Watson, however, has kindly compared them at Cambridge 
for me, and I accept his conclusion—Camp Bowie, Ariz. (446); also 
obtained by Dr. Loew from Mount Turnbull, in the same region.
