72 ENGLISH BOTANY. 



Stipules lanceolate, scarious, with a strong central nerve. Scapes 

 2 to 4 inches high in flower, attaining to 6 inches in fruit, clothed 

 with rather long spreading hairs, hearing 6 to 14 flowers in a com- 

 pact terminal head. Flowers f inch long, purplish-hlue, more rarely 

 white. Calyx-tuhe cylindrical-oblong, sj)litting as the pod enlarges ; 

 teeth linear-lanceolate, about one-fourth the length of the tube; 

 both teeth and tube clothed with rather bristly hairs intermingled 

 with black glandular points. Corolla nearly twice as long as the 

 calyx ; keel with a dark purple blotch at the apex. Pods f to 

 f inch long, sessile, swollen, bending down at the apex, which is 

 acuminated into a point, ojjening along the upper suture, clothed 

 with short curled hairs. Seeds roundish-kidneysliaped, much com- 

 pressed, deeply notched at the circular hilum, olive, dim. Plant 

 greyish-green, the young leaves almost white from the abundance of 

 their silky hairs. 



I have not seen the Ilussian plant 0. uralensis, from which Koch 

 says this species differs. Dr. Walker-Arnott considers them the 

 same. Most probably they are merely sub-species; in which case 

 the name O. uralensis might be retained for the aggregate species, 

 and O. Halleri for the Western form.

 Astragalus campestris, Linn. Sm. Eng. Bot. No. 2522. 



Rootstock branched, many-headed. Leaves all radical, with 

 numerous pairs of elliptical leaflets covered with silky hairs. 

 Scapes ascending, scarcely exceeding the leaves, with spreading 

 hairs. Plowers in a compact globose or oval head, which elongates 

 very slightly in fruit. Bracts narrowly elliptical-lanceolate, longer 

 than the calyx-tube. Pods ascending, inflated, oblong-ovoid, taper- 

 ing and recurved at the apex ; upper suture much inflexed, forming 

 an imperfect dissepiment reaching to the central axis of the pod ; 

 lower or dorsal suture not winged, but having merely a ridge pro- 

 jecting into the inside. 



On rocks facing the south a little to the north of Bradoonie, 

 Clova, Eorfarshire. 



Scotland. Perennial. Summer. 



Extremely similar to 0. Halleri, but usually a larger and 

 sfouter plant, the leaflets being from | to 1 inch long, usually broader 

 in proportion and less acute, with the silky hairs more distant, espe- 

 cially on the upper surface. Scapes 4 to 8 inches high, usually 

 civved towards the base. Flowcr-he.ads rather shorter than those
