ground, mountain pastures, hills and rocky peaks everywhere. 
At most seasons, but chiefly March-June. — St. slender but stiff 
and firm ; the primary or main st. always erect though often 
very short, with diffuse or decumbent mostly prostrate or pro- 
cumbent branches 6 in. -2 ft. long spreading widely all round, 
sparingly subdivided and often dark violet or purple. St. pe- 
tioles stip. ped. and cal. more or less hairy or pubescent, some- 
times nearly smooth. L. distant few and small in proportion ; 
1. -stalks 2-3 lines long ; lfts. 2-5 lines long, dark gr. imspotted, 
very slightly glaucous, smooth or only occasionally sprinkled 
with a few hairs, the upper in Mad. often subacute or at least 
not retuse. Stip. half-ovate acute entire, rounded but not 
auricled or cordate at the base. Ped. longer or shorter than 
the 1. Heads rather large 4-5 lines in diam., at first lemon-y., 
afterwards becoming tawny -brown or chestnut, dry and sca- 
rious, at first hemispherical but soon becoming globose or shortly 
oval, approaching more or less to oblong, and very obtuse or 
truncate. Cal. pale gr., 2 upper teeth short ovate, 3 lower 
long linear-setaceous, subpilose unchanged after fl. FI. small 
lemon-y., the lower sessile, the upper shortly stalked. “ Wings 
divaricate,” Koch. Standard much enlarged after fl. becoming 
tawny- brown dry and scarious, arching or curling down over 
the pod. Pod narrow smooth elliptic pointed at each end. 
Style the length of the pod, hooked at top. Seeds 1 or 2 
“mostly 2 ” (Brot.) y. oval, the radicle not prominent. 
The prostrate or procumbent and more erect forms of this 
pi., with ped. longer or shorter than the 1., are often different 
stages only of the same individual ; and all attempts to distin- 
guish them by verbal definition are frustrated bv endless inter- 
mediate transitional variations. The ordinary form however in 
Mad. is certainly that more diffusely spreading or procumbent 
state, with ped. longer than the 1., to which belong the following
