PUosulous at least on young branchlets and ventral angles of h-stalk, the lfts<br />

pubescent on both faces, beneath only, or subglabrous ciliolate; lvs 7-20 cm;<br />

petiole (measured to petiolar gland) 4-17(-19) mm; gland either between proximal<br />

pair or on If-stalk between pulvinus and first pair, sessile or subsessile, squatly<br />

or slenderly ovoid or subglobose 0.6-1.5 x 0.5-1.3(-1.5) mm; lfts (8-) 10-16 pairs,<br />

the distal pair 12-23(-25) x (3.5-)4.5-7.5(-8.5) mm, the shorter proximal pairs to<br />

(4.5_)6-10 mm wide; body of pod (6-)7-ll x 0.45-0.6 cm.—Collections: 18.<br />

Thickets and roadsides, sometimes weedy, often calciphUe, sea level up to<br />

±600 m, scattered along the s. coast of Hispaniola from La Altagracia, Dominican<br />

Repubhc, to Departement du Sud, Haiti, thence n. to lowlands of centr. Departement<br />

de rOuest; s.-centr. Jamaica (Clarendon Pa., Middlesex).—Fl. (IX-)X-IV.<br />

Pilosulous and glabrate phases of var. berteriana appear neatly segregated<br />

geographically, the former being known only from southeastern Dominican Re­<br />

public (D. F. and La Altagracia) and from Jamaica, ah known intervening populations<br />

being of a less hairy type. We can find no substantial difference between<br />

the Jamaican and east Dominican plants.<br />
