Woad-waxen. Base Broom. (Fig. 2062.) 
Genista tinctoria I, Sp. Pl. 710. 1753. 
Branching from the base, not thorny, the sterile shoots de- 
cumbent, the flowering ones erect, stiff, 1°-2° high, branched 
above, slightly pubescent. Leaves 1-foliolate, sessile, lanceo- 
late or elliptic-lanceolate, %4/-114’ long, glabrous or with 
scattered hairs, acute at the apex, narrowed at the base, en- 
tire, shining; stipules none; racemes numerous, terminal, 
1/-2’ long, few-flowered; bracts ovate-lanceolate, acute; 
flowers yellow, nearly sessile, about 6” long; calyx bracteo- 
late at the base, its 3 lower teeth narrower than the 2 upper; 
pod about 1/ long, flat, glabrous. 
On dry hills, Maine, Massachusetts and eastern New York. 
Naturalized from Europe. Native also of northern Asia. Sum- 
mer. Known also as Green-Wood, Dyer’s-broom, Dyer’s-green- 
weed, Dyer’s-whin and Alleluia. 
Q. CYTISUS L. Spal 3 One 75S. 
Shrubs, often stiff or spiny, with 3-foliolate or 1-foliolate leaves, and showy clustered 
flowers, mainly in terminal racemes. Calyx 2-lipped, the teeth short; standard ovate or 
orbicular; wings oblong or obovate; keel straight or curved. Stamens monadelphous; an- 
thers alternately larger and smaller. Ovary sessile, many-ovuled; style incurved. Pod flat, 
oblong or linear, pubescent or glabrous, several-seeded; seeds strophiolate. [From Cythrus, 
one of the Cyclades, where the first species was found. ]

Sarothamnus scoparius Wimm.; Koch, Syn. Fl. Germ. 152. 1837. 
Stiff, wiry, 3°-5° high, much branched, nearly glabrous. 
Branches elongated, straight, nearly erect, angled; lower 
leaves petioled, 3-foliolate, the leaflets obovate, acute, or 
mucronate-tipped, 3/’-5’’ long, entire, narrowed at the base; 
upper leaves sessile, often 1-foliolate; stipules none; flowers 
bright yellow, nearly 1’ long, in elongated terminal leafy 
racemes; pedicels solitary or 2-3 together, 3//-5’’ long; pod 
flat, glabrous on the sides, but ciliate on the margins, 1/—2/ 
long; style slender, at length spirally curved. 
In waste places, Massachusetts to Delaware and Virginia. Also

or naturalized from Europe. Bannal, Besom. Summer. 
10. MEDICAGO L, Sp. Pl. 778. 1753. 
Herbs (a single shrubby species in southern Europe), with small 3-foliolate leaves, and 
small yellow or violet flowers in axillary heads or racemes, Leaflets commonly dentate, 
pinnately veined, the veins terminating in the teeth. Calyx-teeth short, nearly equal; 
standard obovate or oblong; wings oblong; keel obtuse. Stamens diadelphous, the 1 op- 
posite the standard separate from the other 9; anthers all alike. Ovary sessile or nearly so,
