Mexico, growing with Delphinium glaucum, Wats, and Eupatoriiim 

 grandidentatiiin, DC, in flower and fruit .Sept. 15, 1880. 



It is hard to establish, and somewhat hazardous to propose new 

 species of Polcmoniiim. The claim of specific rank for this very strik- 

 ing and beautiful plant I base upon the shape and color of the corolla. 

 No other species but/*, confcrtum shows a corolla whose limb is really 

 funnelform, that is, not at all spreading ; nor has any other form red- 

 yellow flowers which show no tinge of blue or purple or flesh-color, 

 even in fading. Its nearest ally is F. foliosissimum, while it has more 

 the look of P. carnciiin. 



Pentstemon pauciflorus. — Stems 2 feet high, suff'rutescent at 

 base, and with a few strict branches; the whole plant clothed 

 with a very minute puberulence which is retrorse, except upon 

 the inflorescence, where it is spreading .and glandular ; leaves 

 linear, sessile, 1-2 lines wide, the lower 2-3 inches long, the upper 

 gradually 'shorter ; racemes few-flowered (only one pedicel from each 

 pair of bracts); sepals ovate- to oblong lanceolate ; corolla tubular, 

 more than an inch long, bright scarlet, strongly bilabiate, the three low- 

 er lobes usually somewhat reflexed; sterile filament smooth ; capsules 

 acuminate. 



On a bluff" of the Gila River \x\ the extreme south-western part 

 of New Mexico near the border of Arizona, in flower August 30, 

 1880. Probably rare, as only two plants could be found. The spe- 

 cies belongs to the Elmigcra sub-division of the genus, and the flowers 

 look like those of P. harhatus, but the corolla is more deeply lobed 

 and less stongly bilabiate than in that species, while the habit of the 

 plant is very unlike that of any of the forms of it. 



Pentstemon pinifolius. — Stems 1-2 feet high, shrubby and 

 much branched, the lower }^-^ naked and marked with the scars of 

 the fallen leaves, the upper branches densely clothed v\ ith linear-fili- 

 form, glabrous, shai ppointed, one inch long leaves,which are attenuate 

 below, but widen at the very base into ciliolate margins by which the 

 o-iposite paiis are nearly, or most usually completely connate ; the slen- 

 der thyrsus few-flowered ; pedicels and lanceolate-acuminate sepals glan- 

 dular hairy ; corolla an inch and a half long.narrowly tubular, scarlet, the 

 nearly linear segments almost a third the length of the tube, the low- 

 er bearded, but not at all reflexed; capsule ovate-oblong, not acumin- 

 ate. 



Summits of the San Francisco range, back of Chfton, in south-eastern 

 Arizona, growing in crevices of rocks with Eendlera Utaheiisis,GrQQne, 

 and flowering in September, 1880. 



'A near relative of the preceding species, yet well marked, and 

 of very different aspect, with its lower, woody branches naked, and 

 the upper clothed with the dense pine-like foliage. The corollas are 

 not at all strongly bilabiate, and in all the dried specimens their color 

 has faded to yellow. 



Habenaria BREViFOLiA.^Stem a foot or two high and stout; 

 leaves numerous, mostly less than 2 inches long, all but the lanceolate 

 uppermost ones loosely sheathing the stem; bracts linear-lanceolate, all 

 but the uppermost exceeding the greenish flowers, which are numer-
