1904 | NELSON: ROCKY MOUNTAIN PLANTS 263 
I know of no near ally of this species. It is based on Mr. Goodding’s no. 
678, from southern Nevada, “ The Pockets,” April 30, 1902; ‘‘in the crevices 
of the rock.”’ ‘ 
’Hofmeisteria viscosa, n. sp.—Allied to H. pleuriseta: stems 
decumbent at base; lignescent below, grayish-white with glab- 
rous bark; the upper herbaceous part granular-viscid; leaves 
slightly viscid, greatly reduced as to the blade; the lamina often 
reduced to a broadly linear-subulate point, frequently with I or 
2 teeth near the base, from one-third to one-sixth as long as the 
slender petiole which is often 3°™ or more long: heads about 25- 
flowered, at the ends of the slender naked peduncles in 2-7 
capitate clusters, the pedicels very short: involucral bracts 
oblong-linear, abruptly short-acuminate, scarious with three par- 
allel green nerves: pappus of a few slender bristles (8-12); the 
squamellae wanting or if present represented by a few (1-6) 
variable bristles; corolla shorter than the pappus, its tube with 
minute scattered stipitate glands: the club-shaped styles included 
or at least not noticeably exserted: akene very short, ovate- 
oblong. 
This species is somewhat at variance with the genus in the congested 
heads. It differs from all the species in its leaves and from its nearest ally 
as well as the others in floral characters. 
Secured in southern Nevada, at “The Pockets,” April 30, 1902, on dry 
stony bottom lands; no. 671. 
~Chrysopsis imbricata, n. sp.—Stems few to many from the 
crown of the root, quite simple, decumbent-ascending, 3-4" 
‘ong, subcinerous, the pubescence short and close with some 
longer hirsute hairs: leaves very numerous, broadly oblong or 
narrowly elliptic, sessile, often broadly obtuse, abruptly apicu- 
late, sometimes lanceolately narrowed, grayish-hirsute; usually 
crowded till they appear imbricated, with smaller fascicled ones 
in the axils, the lower wanting at anthesis; the floral leaves 
reduced and often ciliate: heads several, closely glomerate at 
the summit of the stems, 10-14™™ high: involucre cinereous- 
hirsute: rays several, conspicuous, distinctly nerved: pappus 
fuscous: akenes silky. 
The writer’s no. 8618, from Pike’s Peak, September 1, 1901, is taken as 
the type. Dr. Clements’s no. 39, from the same region, is this species, but
