Ulex. ] XXV. PAPILIONACER, 103 
On heaths and sandy or stony wastes, more strictly western than JU. 
europ@us, as it does not cross the Rhine, but often intermixed with that 
species, Very abundant in Britain. #7. swmmer and autumn, whilst the 
common F. is in fruit, There are two forms, sometimes very distinct, at 
others running much one into the other ; one, the original U. nanus, found 
chiefly in the plains of eastern England, is very dwarf and procumbent, 
with the calyx about 4 lines long; the other, under the name of U. Galli, 
Planch, is more erect, with the calyx about 5 lines long, and is more fre- 
quent in western England, often covering large tracts in the Welsh 
mountains. 
Il. GENISTA. GENISTA. 
Low branching green shrubs or undershrubs, with simple (or in a very 
few exotic species trifoliolate) leaves and yellow flowers. Calyx with 5 
teeth, the 2 upper ones much longer than the 3 lower. Standard oblong ; 
keel usually reflexed after flowering. Stamens all united in a complete 
sheath. Stigma usually oblique. Pod longer than the calyx. Seeds 
several, not strophiolate. 
A numerous genus chiefly in the Mediterranean region and western 
Asia, the few British species easily distinguished by their foliage and the 
shape of the petals. Many exotic species, however, present so much 
variety, that the general circumscription of the genus, and its distinction 
from Cytisus and other allied genera, are very differently viewed by 
different botanists. 
No thorns. Pod narrow, much flattened. 
Corolla and pod without hairs. Branches erect or ascending . 1. G. tinctoria, 
Corolla and pod hairy. Branches mostly prostrate . : - 2. G. pilosa. 
Lower branches very thorny. Pod short and inflated . . . 3 G. anglica. 
1. G. tinctoria, Linn. (fig. 228). Dyer’s Genista (Greenweed).— 
Stems woody, branching and decumbent at the base, the flowering branches 
erect or ascending, 1 to 14 feet high, hard and stiff, but green. Leaves 
sessile, from narrow-lanceolate to broadly elliptical or nearly ovate, glabrous 
or nearly so, and often shining. Flowers in short racemes at the ends of 
_ the branches, each one shortly stalked in the axil of a lanceolate bract, 
with very small bracteoles below the flowers. Calyx short, all the teeth 
ending in a short, fine point, the upper 2 broadly lanceolate, the 3 lower 
very narrow. Petals about 6 lines long. Pod nearly an inch long, 
flattened, and quite glabrous. 
In pastures, thickets, and waste places, throughout central and southern 
Europe, across Russian Asia to the Baikal, and northward to southern 
Sweden. Frequent in the greater part of England, south of Scotland only, 
and rare in Ireland. Fl. summer, rather early. The common form is 
erect, with lanceolate leaves; in rich meadows it becomes very luxuriant 
with ovate leaves; in dry rocky soils the stem is more branched, and 
almost prostrate, like the G. pilosa, from which it is always known by its 
more pointed leaves, and glabrous flowers and pods. [A decumbent hairy 
form found at Kynance Cove is Var. humifusa, Syme. | 
2. G. pilosa, Linn, (fig. 229). Hairy Genista.—Stems woody and 
prostrate, with numerous short, hard branches. Leaves shortly obovate or 
lanceolate, obtuse, glabrous above, but covered underneath with short, 
silky hairs. Flowers smaller than in G. tinctoria, of a bright yellow, on
