vegetable soil ; I have only found it on the ground around the Grand 

 Rapids. 



(24) Phlox sp. ; shrubby ; leaves opposite, sessile, linear, under side 

 smooth, upper somewhat pilous ; calyx ciliated ; this handsome plant 

 may be what Pursh has given as P. speciosa 1 ; most likely his description 

 taken from an imperfect specimen ; flowers white, tinged with pink or rose 

 colour at expansion, and then assumes a deeper hue of a bluish-purple ; 

 a foot to 18 inches ; growing in small patches or tufts on all dry light 

 soils ; very plentiful on the plains near the junction to Lewis and 

 Clarke's River with the Columbia. 



(25) Cruciferae, Coronopus 2 sp. ; annual ; flowers white ; a foot to 

 18 inches high ; plentiful along the banks of the Columbia from the Falls 

 upwards. 



(26) Sisyrinchium sp. ; annual ; 8 inches to a foot high ; on the 

 summit of the low hills ; plentiful ; a white-flowered variety is usually 

 found with it. 



(27) Salix sp. ; male and female ; a small tree, or more properly a 

 shrub, frequenting mountain springs and rivulets. 



(28) Oxytropis Lambertii ; abundant in rocky, sandy situations ; grows 

 very luxuriant on limestone hills from the Great Falls upwards ; at the 

 mouth of the Spokane River a variety, or may prove a second species, 

 is found of more slender growth ; not so silky ; the calyx longer and 

 not swollen. 



(29) Trillium sp. ; perennial ; flowers sessile ; reddish-brown leaves, 

 nearly orbicular ; on the margins of mountain pools and rivers, among 

 low brushwood ; a fine species ; plentiful at the junction of the Spokane 

 River. 



(30) Cruciferae, annual ; flowers rose colour or pink ; leaves sessile, 

 linear, minutely dentate ; whole plant scabrous ; a plant a foot to 2^ high, 

 rarely branching ; on the gravelly banks of rivers, under solitary pine- 

 trees ; plentiful. 



(31) Phlox sp. ; a small shrubby species, 6 to 10 inches high, in individual 

 tufts or plants, on the shores of rivers and limestone hills ; flowers white 

 and faint rose colour; this very handsome plant, which comes near 

 P. setacea,3 is found in conjunction with the other species. 



(32) Astragalus sp. ; perennial ; stemless ; leaflets numerous, silky, 

 flowers white ; a low plant, 4 to 12 inches high ; found among stones 

 in the channel of the river ; not so plentiful as Oxytropis. 



Dodecatheon ; probably the same as that collected in 1825, in the Upper 

 Country ; on the elevated plains, under the shade of pines, a fine white 

 variety takes the place of this species ; when both are seen together 



* 1 Phlox speciosa of Pursh is rarely to be seen in perfect seed. The intense heat, 

 which generally sets in in May, long ere they arrive at maturity, completely dries 

 them up. I found with difficulty a few on the plains in June, and in July on the 

 high mountains near the north and south branches of Lewis and Clarke's River, 

 I found a larger quantity, being in a more temperate situation. (Aiigust 5th.)
