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, bearing 6 to 14 flowers in a com- 
pact terminal head. Flowers ? inch long, purplish-blue, more rarely 
white. Calyx-tube cylindrical-oblong, splitting 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 } to 
% inch long, sessile, swollen, bending down at the apex, which is 
acuminated into a point, opening along the upper suture, clothed 
with short curled hairs. Seeds roundish-kidneyshaped, 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 Russian plant O. 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.

Pirate CCCLXXIV. 
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. Flowers 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, Forfarshire. 
Scotland. Perennial. Summer. 
Extremely similar’ to O. Halleri, but usually a larger and 
stouter 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 
curved towards the base. Flower-heads rather shorter than those
