1826, JUNE. PLANTS COLLECTED 187 



on. Employed exposing my paper to the sun and turning my plants until 

 twelve o'clock, when I went out and gleaned the following : 



(127) Pentandria, Monogynia, perennial ; a second species of the genus 

 (115), also very fragrant during the night; plant glaucous; stem smooth, 

 white, purple at the joints, brittle, and somewhat succulent ; leaves ovate- 

 obtuse, entire ; root creeping and produces shoots like the genus Salix 

 and Populus when exposed above ground ; a low but wide-spreading 

 plant ; plentiful on the plains, near the junction of Lewis and Clarke's Eiver 

 with the Columbia ; would be a valuable addition to the garden ; this I 

 think is the plant I saw last year at the Falls and had not time to look at 

 at the moment (that found this year at the Stony Island a second species). 



(128) Pentstemon e~p. ; perennial; very smooth and glaucous; radical 

 leaves lanceolate, with cauline amplexicaul, cordate-acute ; corolla 

 nearly equally five-cleft, fine blue and rarely with any other colour 

 (sometimes assuming a tinge of purple on the tube after a few days' 

 expansion) ; sterile filament shorter than the perfect, bearded on the 

 upper side, hairs light brown ; peduncles, many flowered ; a most beautiful 

 species, a foot to 3 feet high ; abundant on the banks of Wallawallah 

 Eiver, the only place I have as yet seen it ; perfectly distinct from 

 P. 108 ; both will, I think, prove new. 



(129) Myosotis (?) sp. ; perennial ; leaves alternate, nearly sessile, 

 lanceolate-obtuse, entire, glaucous ; stem glaucous and somewhat 

 succulent ; flowers white, dark in the centre ; rare ; on the banks of 

 the Wallawallah River, on moist ground. 



(130) Oenothera sp.; annual; leaves small, glabrous, sessile, alternate, 

 linear ; capsule long, slender, twisted ; flowers faint rose colour ; a 

 minute plant, never exceeding 6 or 8 inches high ; on the plains ; 

 abundant in dry sandy soils. 



(131) Eriogonum sp. ; perennial ; leaves linear-lanceolate, villous ; 

 flowers white ; abundant on the plains. 



(132) Rosa sp. ; seems to be the only species ; on the banks of 

 rivers on the plains ; flowers large.

(133) Clematis sp.; flowers white; on shady places, among rocks; 

 not plentiful. 



(134) Erigeron (?) sp. ; pubescent ; flowers white ; 8 inches to a foot 

 high ; on rocky places ; rare. 



(135) Orobanche sp. ; annual (not a parasite) ; abundant on the dry 

 sand-scorched plains. 



(136) Diadelphia; perennial; stem low, branching; leaves pinnate; 

 leaflets linear, pubescent ; legume many-seeded : flowers blue and purple ; 

 on the plains ; abundant. 



(137) Allied to Rumex, perennial; leaves glaucous, linear-lanceolate, 

 entire ; wings of the capsule bright scarlet ; root creeping ; a strong 

 coarse plant ; abundant on the plains at the junction of Lewis and 

 Olarke's River.

 the three following :
