1. O. campestris, DC. (fig. 271). ‘Yellen Waené. —Stock short 
and tufted, covered with the Are stipules and leafstalks, seldom lengthening 
into shortly ascending branches ; the leaves and peduncles usually proceed- 
ing from the stock. Leaflets 10 to 15 pairs, with an odd one, oblong or 
lanceolate, and hairy ; the common leafstalk 2 or 3 inches long. Peduncles 
rather longer, with a short spike of pale yellow flowers, tinged with purple. 
Calyx hairy, 4 or 5 lines long ; corolla twice that length; the point of the 
keel short, straight, and erect. Pod erect, ovoid, covered with short, 
usually black, hairs; the partition projecting to about the centre of the

America. In Britain only in one spot, among the Clova mountains of 
Scotland. £7. summer. 
2. O. uralensis, DC. (fig. 272). Purple Oxytrope.—Stock short and 
tufted, with the foliage, inflorescence, and pod of O. campestris, but the

two cells. The point of the keel is short and straight, as in O, campestris. 
O. Halleri, Bunge. 
In mountain pastures, in central Europe and Russian Asia, descending 
to a low level in the north, and penetrating far into the Arctic regions. 
Not uncommon in Scotland, in dry, hilly pastures, chiefly near the sea, but 
does not descend to England. Fl. summer.

Slender, spreading annuals, with pinnate leaves and axillary peduncles,

rating when ripe into 1-seeded articles. 
A genus of few, chiefly south European, with one south American species, 
differing from Coronilla chiefly in their siender habit and obtuse keel.

15, small, obovate or oblong, the lowest pair at some distance from the 
stem. Stipules very small. Peduncles very slender, with an umbel of
