 from 0. geminiflora, Lag. p. 160. no. 29. and 0. btflora of

13 TRIFOLIUM SPINULOSUM (Dougl. mss. Hook, fl. bor. amer. 

 133.) prostrate, glabrous ; leaflets oblong, acute at both ends, 

 spinulously denticulated, and terminating in a stiff spine ; sti- 

 pulas ovate, acuminated, shining, serrated ; involucrum 1 -leaved, 

 laciniately multifid ; heads of flowers globose, longer than the 

 involucrum ; calycine teeth narrow- subulate, pungent, straight, 



a little shorter than the corolla. !. H. Native of North- 

 west America, very common near springs in the valleys between 

 Spokan and Kettle Falls. This species is allied to T.jimbriatum, 

 Lindl. p. 185. no. 53. of the present volume, but is sufficiently 

 distinct. The vexillum and wings are shorter and more acute, 

 the flowers smaller, white, the keel and wings tipped with a fine 

 purple, and the whole plant more slender. This plant might 

 prove perhaps very useful as a clover, the herbage forming a 

 dense, short sward. It is extremely nutritive, and preferred to 

 every thing else by deer and horses in its native country.

 linear, serrulated ; stipulas subulate ; scape naked ; flowers um- 

 bellate, becoming at length reflexed ; corolla twice the length of 

 the calyx ; calycine teeth nearly equal, subulate ; ovary biovu- 

 late. %. H. Native of the western region of Caucasus, at 

 the height of 3600 or 4300 feet. Allied to T. alpiman, Lin.

15 LOTUS AUSTRA'LIS (Andr. bot. rep. 624.) stem pilose, her- 

 baceous, and perhaps procumbent ; leaflets and stipulas about 

 equal in size, obovate-lanceolate ; peduncles elongated ; flowers 

 3-6, disposed in racemose heads at the tops of the peduncles ; 

 calycine segments longer than the tube ; stamens diadelphous, 

 the alternate filaments of the 9 connected ones very dissimilar 

 to the others. I/ . G. Native of New Holland. Flowers 

 large, showy, pink, or rose-coloured. Sims, bot. mag. 1365. 

 This plant should follow L, Ardbicus, Lin. p. 197. no. 27. of the

16 HOSA'CKIA UNIFOLIA'TA (Hook, fl. bor. amer. 135.) plant 

 decumbent, hairy, much branched ; leaves usually with 1 leaflet, 

 rarely with 2 or 3, almost sessile ; leaflets oval, acute at both 

 ends; stipulas obsolete; peduncles 1 -flowered, with 1 ovate 

 bractea under the flower. O- H. Native of North America, 

 on the shores of the Columbia. Corolla yellow. This species 

 approaches H. deciimbens, Benth. in the size and shape of the 

 leaflets and in the hairiness, but in its flowers to H. parvijlbra, 

 Benth. p. 200. no. 4. of the present volume.

 leaflets ; leaflets broadly rhomboid-ovate, acute, mucronate, ob- 

 scurely glandular, terminal one on a long petiole ; racemes pe- 

 dunculate, loose, axillary, longer than the leaves ; calyx much 

 inflated, hairy, hardly shorter than the corolla, with the teeth 

 nearly equal. 3. H. Native of North America, on the banks 

 of streams, in open sandy, and gravelly soils, from the great 

 falls of the Columbia to the Rocky Mountains. Legumes glan- 

 dular, 1-seeded. It is easily distinguished from the other species 

 by its broader leaflets, as well as by its large inflated calyx, 

 which almost conceals the flower. The plant comes nearest to 

 P. incana, Nutt. p. 203. no. 42. of the present volume. 



Bladder-czdyxed Psoralea. PI. 1-j- foot. 



18 PSORA'LEA BRACHIA'TA (Dougl. mss. Hook, fl. bor. amer.
