118 THE PEAFLOWER TRIBE. 
ground to the length of 2 feet or even more. Stipules free. Leaflets 
11, 13, or more, ovate, 1 to 14 inches long, the common leafstalk fully 
6 inches long. Flowers about 6 or 7 lines long, of a dingy yellow, 
spreading or pendulous, in racemes rather shorter than the leaves. 
Pods erect, curved, glabrous, above an inch long, completely divided 
into 2 cells by a thin double partition, with 6 to 8 seeds in each half. 
In rather dry, open woods, and bushy places, over the greater part 
of Europe and Russian Asia, except the extreme north. Not common 
in Britain, although it ranges over a great part of England, especially 
the eastern counties, and “southern Scotland, rarer in the north ; not 
recorded from Ireland. Fl, summer. 
XIi. OXYTROPIS. OXY'TROPE. 
Low, tufted perennials, only differing from Astragalus in the keel, 
which has a small point at its extremity, either erect or slightly recurved, 
and in the pod, which has an incomplete longitudinal partition project- 
ing into the cavity from the angle next the vexillum (the one which 
bears the seeds), not from the angle next the keel. 
A considerable genus, but not so numerous nor so widely spread as 
Astragalus, and chiefly confined to mountain stations or high latitudes 
‘in Europe, Asia, and North America.

1. O. campestris, DC. (fig. 272). Yellow. O.—Stock short and 
tufted, covered with the old stipules and leafstalks, seldom lengthening 
into shortly ascending branches; the leaves and peduncles usually pro- 
ceeding 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 cavity. 
In mountain pastures, and on alpine rocks, common in the great moun- 
tain-ranges and Arctic regions of Europe, Russian Asia, and northern 
America. In Britain only in one spot, among the Clova mountains of 
Scotland. Fl. summer. 
2. O. uralensis, DC. (fig. 273). Purple O.—Stock short and tufted, 
with the foliage, inflorescence, and pod of O. campestris, but the whole 
plant is much more densely covered with soft, silky hairs ; the flowers 
are of a bright purple, and the pod is more completely divided into 
2 cells. The point of the keel is short and straight, as in 0. cam- 
pestris. 
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. 
: XIII. ORNITHOPUS. BIRD’S-FOOT. 
Slender, spreading annuals, with pinnate leaves and axillary pe- 
duncles, bearing a head or umbel of small pink or white flowers. Calyx “a
