176 DOUGLAS' JOURNAL 



Monday, 22nd. Crossed the Columbia to Dease River, one of its 

 northern branches, which I ascended ten miles in a canoe with two Indians 

 and a Mr. Kittson who was going to examine it, being never entered before 

 by Europeans. I walked along the banks while they came up with the 

 canoe ; found the stream so very rapid that to get higher was fruitless, so 

 we just left ourselves time to return in the evening. Supposed to take its 

 waters from the Rocky Mountains. Found in blossom what 1 supposed to 

 be Pentstemon some weeks ago. 



(71) Didynamia, Angiospermia ; calyx five-leaved, bibracteate ; corolla 

 bilabiate, lower [lip] plaited and bearded ; bark slightly fringed ; anthers 

 lanuginous ; sterile filament shorter ; four to seven hairs on the upper- 

 side near the middle ; seeds angular ; stem fruticose, reclining ; leaves 

 opposite, sessile, lanceolate, smooth, slightly denticulate, floral, broader 

 and more obtuse, somewhat pubescent ; upper part of the stem, peduncle, 

 and calyx equally so ; this plant common in some points to Pentstemon 

 frutescens ; if it is, the anthers and sterile filament must have been 

 overlooked ; seeds being not membraneously margined makes it differ 

 from that genus ; it may be an anomaly ; abundant on rocky and gravelly 

 soils on the upper parts of the Columbia and its branches. 



(72) Polemonium (?), perennial; calyx five-cleft; corolla partially 

 rotate ; tube short, closed at the base with valves ; stigma trifid, cap 

 not in perfection ; leaves pinnate, slightly pubescent ; calyx somewhat 

 glutinous ; flowers bright blue ; a delicate little plant, 10 to 20 inches 

 high ; on rocky situations and light soils ; in great abundance on the 

 banks of this river, the only place it has come under my notice. 



Tuesday, May 23rd. As usual went out in search of any plant that 

 might appear different from that already collected ; found the following : 



(73) Umbelliferae, perennial ; root large, fusiform, tastes somewhat like a 

 parsnip ; radical leaves entire (sinuated when in rich damp soils), lanceo- 

 late, smooth, three-nerved, floral pinnate, amplexicaul ; flowers sulphur- 

 yellow colour ; plentiful in all low swampy grounds ; the roots are gathered 

 by the natives and boiled or roasted as an article of food (taste insipid) ; 

 called by them Missouii.i 



(74) Umbelliferae, perennial ; leaves ternate, cordate, serrate, smooth ; 

 flowers yellow ; like the former, found on low wet ground and margin of 

 mountain springs. 



(75) Heuchera sp. ; perennial ; scape pilous, leaves lobed, acute, 

 upper side smooth, under nerved and slightly pubescent, dentate, 

 and mucronate ; flowers white ; this does not differ much from H. 

 caulescens 2 of Pursh, may probably prove to be it ; abundant on the 

 subalpine hills in rocky places, usually in partially shady spots ; a fine 

 plant. In the course of the day found abundantly Collomia linearis 

 of Nuttall on the channel of the Columbia and its creeks, in sandy 

 soils ; less luxuriant than in the lower country. Observed a large plant 

 belonging to Malvaceae, in open woods, not yet in blossom, also a small 

 species of Artemisia, in rocky places, with pinnate, revolute leaves, woolly
