295. Lithospermum pilosum, Nutt. ex char. This is Fendler's No- 

 626 and Wright*s 1562.

297. Phlox Hoodii, Richards, var. foliis rigidioribus ^ 



rigida, Benth. ? P. brevifolia, Kutt. in Herb. P. muscoides and P. 

 hryoides of Nuttall both belong to P. Hoodii.

301. Dracocephalum parviflorum, Nutt. " The only representative of 

 Labiatse in the mountain region,'' 



302. Salvia Pitcheri, Torr. Prairies in Kansas. This mtist be the 

 S. elongata of Dr. Torrey in James's collection. It is intermediate be- 

 tween S. azurea and S.farinacea,-^tvfO Salvias which would seem to be 

 distinct enough. 



303. Scutellaria resinosa, Torr. in Ann. Lye. N. Y. Upper Platte. 



304. Qmtiana Parryi, sp. nov., Engeim. in Trans. St. Louis Acad., 2, 

 p. t. 10. " Near the foot of alpine slopes." This is, says Dr. Engelmann, 

 "a very handsome species, growing in tufts, each stem bearing several 

 large, purplish-blue flowers with bifid folds, and enclosed by a pair of 

 boat-shaped bracts. Leaves rounded, fleshy, glaucous. Kearly allied to 

 G. calycosa and G. Menziesii, which, however, have single flowers, with- 

 out the calyculate bracts peculiar to our species, and to the Siberian &> 

 sepUmfida, with long folds slit into numerous bristling lobes." Engelm>. 

 The plant of Kreusfeldt, in Gunnison's Expedition, referred to 6. affina 

 m the second volume of the Pacific Railroad Report, is of this species, 

 but with narrower leaves, and Fremont's No. 360 (1845) is a small- 

 leaved form of it, which also occurs in Mr. Howard's collection (Herb. 

 Acad. Philad.), in one instance with a six-lobed corolla. 



305. Gentianafrigida,B.^nkQ,ysiX.algida,Gr\^^h. "Abundant on 

 high alpine slopes, in moist places, growing in small tufts among Grasses 

 and Carices." "Apparently an intermediate form between the European 

 G.frigida and the Siberian G. algida. Stems lower than in the latter, 

 only 4 or 5 inches high ; the leaves narrower ; flowers fewer and closely 

 sessile; calyx often partly slit; lobes of the corolla very acute, greenisa 

 blue, reddish-brown in the dried state, punctate, the folds truncate and 

 crenate." Engeim. This is also in Mr. Howard's collection. New to 

 America, but found as near as Karatschatka. 



306. Gentiana prostrata, var. Americana, Engeim. 1. c. t. 9, fig. lO'l^' 

 "A very small form, single or with few horizontal branches, l-l^ i°!=''^ 

 high, found with No. 309. Distinguished from the European and Asiatic 

 forms by the small, 4-parted deeply blue flowers, nearly entire folds, an^l 

 oblong-linear capsule, attenuated at the base into a short stipe. ^^' 

 misso collected the same form in Russian Arctic America." Mffel"*- . 



135. Gentiana humilis, Stev., Engeim. 1. c. fig. 1-6. G. FremonHh 

 Torr. m Frem. Rep. "Along the moist rrrassy banks of Upper Clear 

 Creek, with Polygonum viviparum, almost hidden among the grasj
