more dilated : sterile filament wholly naked. — Proc. Am. Acad. xvii. 228. — S. California, 

 near San Bernardino, to San Diego Co., Wallace, Parish, W. G. Wright. 



P. stenoph^llus, Gray, p. 266. P. rubescens, Gray, I'roc. Am. Acad. xix. 92, belongs to 

 this species, the discolored flowers having been taken for red instead of purple or violet. — 

 Common through S. Arizona, Lemmon, Pringle, and Northern Mex., Palmer, ISrhaffner. 



Var. dasyph^Uus, P. dasyphyllus, Gray, p. 266, a form with leaves and lower part 

 of stem thickly beset with short retrorse pubescence (New Mexico and adjacent Texas as 

 well as Arizona) , varies into the glabrous state of the species. 



P. lanceolatus, Benth., p. 266. Habit of the Elmigera section : stem a foot or two high, 

 herbaceous to the base or nearly, miuutely puberulent or glabrate and the simpler inflo- 

 rescence glandular : leaves from lanceolate to narrowly linear : corolla scarlet j-ed, an inch 

 and more long, narrowly funnelform ; upper lip erect and 2-lobed, lower 3-parted and 

 spreading: sterile filament glabrous: anther-cells short-oval, explanate in age. — PI. Hartw. 

 22. P. pauciflorus, Greene, Bot. Gazette, vi. 218, narrow-leaved form. — Bluffs of the Gila, 

 S. W. border of New Mexico, Greene. Rucker Valley, S. Arizona, Lemmon. (Mex.) 



P. pinif olius, Greene, 1. c. Next to the preceding, glabrous throughout : stems a foot or 

 two high, decidedly shrubby, much branched, with the herbaceous flowering branches short 

 and slender, racemosely few-flowered . leaves much crowded on the sterile stems, linear- 

 acerose (inch or less long, hardly half a line wide) : sepals broadly lanceolate and acumi- 

 nate, puberulent : corolla an inch or more long, light scarlet, narrowly tubular, not enlarged 

 at the throat ; upper lip 2-lobed and erect ; lower 3-parted and spreading ; lobes uearly 

 linear, slightly bearded at base : anther-cells short-oval : sterile filament dilated and bearded 

 above. — S. Arizona, in the San Francisco and Mogollon Mountains, Greene, and Kucker 

 Valley, Lemmon. 

 P. miser. Next to P. cristatus, p. 266, every way smaller, only a span or two high, pruinose- 

 puberulent, and the contracted inflorescence glandular-viscid but not villous : radical leaves 

 spatulate or obovate ; cauline lanceolate, an inch or less long : sepals lanceolate, merely acute : 

 corolla violet or bluish, only half-inch long, rather tubular than funnelform, the throat little 

 dilated, spreading lobes short, base of lower lip moderately villous : sterile filament with 

 dilated and curved tip hardly projecting from the throat, densely yellow-bearded down one 

 side, the beard stronger and shorter than in P. cristatus. — Eastern Oregon, along the Mai-, 

 heur Rivsr, Cusick. 

 P. Rattani, Gkat. Between P. glaucus and P. Whippleanus : a foot to a yard high, gla- 

 brous below, minutely viscidulous-pubescent above : leaves membranaceous, broadly elon- 

 gated-lanceolate, 3 to 8 inches long, thickly denticulate ; radical and lowest cauline attenuate 

 at base into a margined petiole ; the others half-clasping by a subcordate base : flowers 

 glomerate in the interrupted thyrsus : cymes from the lower axils long-peduncled, upper 

 short-peduncled or subsessile : pedicels short or hardly any : sepals oblong-lanceolate, acu- 

 minate, soft-membranaceous, loose : corolla curved in the bud, slightly oblique in anthesis, 

 pale purple, inch long, campanulate-ampliate above the short tube ; lips short, lower villous- 

 bearded within : anthers and filaments glabrous : sterile filament at length exserted, bearded 

 with some sparse and long hairs: seeds of the genus. — Proc. Am. Acad. xv. 50. — In 

 forests of N. W. California, in Humboldt Co., 1878-79, Rattan. Except for the wingless 

 seeds, this is most nearly related to Chelone nemorosa, p. 259. 



Var. minor, Gray, 1. c. Slender, with oblong leaves only an inch or two long, ob- 

 scurely denticulate: thyrsus simple: flowers one half smaller: sepals attenuate: corolla 

 6 or 7 lines long. — Indian Creek, Del Norte Co., California, Rattan. 



Var. Kleei. Intermediate in foliage, inflorescence, and size of flowers between the fore- 

 going variety and the type : sepals oblong, short-acuminate or obtuse. — P. Kleei, Greene 

 in Torr. Bull. x. 127. — Summit of Ben Lomond, the highest peak of the coast ranges 

 behind Santa Cruz, California, W. C. Klee. 

 P. G-airdneri, Hook., p. 270. The character of alternate leaves (specially noted by Hooker) 

 was overlooked. This holds generally, as to most of the leaves in Washington Terr., coll. 

 Lijall, Howell, Suksdorf, Brandegee. Stems vary from a span to near a foot high. 



Var. Oreganus. Strict : leaves (narrow) even the bracteal ones and most of the pe- 

 duncles opposite. — Mountains of E. Oregon, Cusick, Howell.
