fragrant. Seeds of this handsome Primrose were copiously collected, from 

 which we may hope to have the plant in cultivation. 3S0. P. angustifolia, 

 Torr. 381. Dodecatheox Meadia, L., the same form as Parry's 312. 3S2. 

 Lysimachia ciliata, L. " Mountains at medium height." 60 and 577. Glaux 

 maritima, L., in flower and in fruit. 



LENTIBULARIACE^E. 



5S0. Utricul aria vulgaris, L. ? Without flowers. In a subalpine lake. 



OROBANCHACEiE. 



383. Aphyllon fasciculatusi, Torr. and Gray. 



SCROPHULARIACE2E. 



384. Pextstemon glaber, Pursh ; same as Parry's 260. 3S5. P. acumi- 

 natus, Dough, agreeing with Bentham's character "filamento sterili glabro, " 

 which is very rarely the case, but a very narrow-leaved variety, just P. 

 secundiflorus, Benth., excepting the glabrous sterile filament. " Mountains at 

 low and middle elevations." 386. P. acuminatus, Dough, the ordinary form 

 of the region (P. nitidus, Dough, P. Fendleri, Gray), Parry's 258. 390. P. 

 acuminatum, Dough, in some sets the common broad-leaved form, in others a 

 variety with still narrower leaves than Parry's 264, i. e., a form almost ex- 

 actly passing into P. cccruleus, Nutt., the name which may probably have to 

 be adopted for the combined species. "Plains; May." 3S7. P. uumilis, 

 Nutt., taller than Parry's 257, much larger than Nuttall's specimen. "Low 

 mountains, an early and pretty species." Dr. Lyall has recently collected it 

 in lat. 49, at the elevation of 7000 feet. 388. P. Hallii, n. sp., described 

 in "Revision of Genus Pentstemon," in Proceed. Amer. Acad. 6, p. 70, which 

 memoir see for remarks on most of these Pentstemons. This is a most beau- 

 tiful dwarf species, "not uncommon in the alpine region, descending into the 

 subalpine," the rich blue purple flowers large for the size of the plant. Dr. 

 Parry must have overlooked it in 1861 by confounding it with his 259 (P. 

 glaber, var. alpiniis,) which, externally, it much resembles, but its affinities 

 are with a different group. 389. P. albidus, Nutt. "Plains; flowers white." 

 391. P. confertus, Dough, var. purpureo-caruleus, Gray, Rev. Penst. (P. pro- 

 cerus, Dough) A taller form of this, with large radical leaves, was sparingly 

 gathered by Dr. Parry in the Middle Park. 392. P. glaucus, Graham ? var. 

 stenosepalus, Gray, Rev. Penst. p. 70; the No. 262 of Parry. "South Park 

 and Pike's Peak; alpine and subalpine." 393. P. c.espitosus, Nutt., Gray, 

 Rev. 1. c, p. 66. "South Park, at middle elevations." "Near the Upper 

 Platte, first found by Mr. J. Harbour." Parry. A neat and very dwarf spe- 

 cies, named by Nuttall, but unpublished, having been confounded with P. 

 pumilus. 394. P. pube.-cens, Soland., var. gracilis, Gray, 1. c. P. gracilis, 

 Nutt. 395. P. barbatus, Nutt., var. Torreyi, Gray. 396. P. Harbourii, 

 n. sp., Gray, Rev. Penst. p. 71. "Mount Breckenridge on Blue River, west 

 of the main range, in the high alpine region near perpetual snow." A very 

 distinct and dwarf species, named after its discoverer. 397. Chionophila 

 Jamesii, Benth. High alpine, Pike's Peak, &c. Ripe seed having been 

 collected, we may hope that this most rare and interesting plant may become 

 known in cultivation. 



398. Mimulus luteus, L.* 399. M. Jamesii, Torr., var. Fremontii, Benth.; 

 apparently a form of M. glabratus, HBK. 400. M. floribuxdus, Dough 

 401. M. ritbellus, Gray in Bot. Mex. Bound, p. 116 : but the limb of the 

 corolla apparently yellow. "Subalpine; scarce." The same plant occurs 

 in Dr. Lyalhs collection on our northwestern boundary, from the Cascade 



* M. luteus, L. var. ai.pin'us ; caulibus 3-pollicaribus 6 basi ilecambente vel repcnte 1-3-floris; 

 fyliis plensque sessilibus subinte^errimis. Alpine region, 135a cull. I'arry. 1862. Very glab- 

 rous. Farther north, Dr. Lyall colluoted a similar, but pubiM'uIent and smaller-leaved variety.
