Benth, in Pl. As. Rar. v. 2 (1831) p. 18. Annual ; stems many from a woody rootstock, slender, either diffuse, ascending, prostrate and rooting, or quite erect, glabrous or more or less hispid with weak deflexed hairs. Leaves in distant pairs, 1-2 by 1/3-3/4 in., subsessile, obovate-lanceolate or linear-lanceolate, acute or subacute, shallowly serrate or distantly toothed, with a few hairs on both sides, base tapering. Flowers minute, in many-flowered close or distant whorls, in slender racemes 2-6 in. long ; bracts 1/8 in. long, thick, broadly ovate, acuminate, pubescent, gland-dotted ; pedicels usually longer than the calyx. Fruiting calyx 1/8 in. long, hairy outside and with a ring of hairs in the throat ; upper lip variable in size, oblong, subtruncate, mucronate ; lateral teeth triangular, acute ; the 2 lower teeth lanceolate, awned. Corolla pink or white, 1/8 in. long, hairy ; tube 1/16 in. long ; upper lip with 4 triangular teeth ; lower lip obovate, obtuse, rather longer than the upper. Stamens exserted. Nutlets 1/30 in. long, ellipsoid, compressed, smooth, brownish-black. Fl. B. 1. v. 4, p. 610 ; Grah. Cat. p. 148 ; Trim. Fl. Ceyl. v. 3, p. 368 ; Woodr. in Journ. Bomb. Nat. v. 12 (1899) p. 360 ; Prain, Beng. Pl. p. 845.
This is given on the authority of Graham (Cat. Bo. Pl. l. c.), who mentions its occurrence in the S. Konkan on the authority of Nimmo. I have seen no specimens from the Bombay Presidency ; there are none from that Presidency in Herb. Kew. Dalzell does not include it in his Bombay Flora, and Woodrow in his list of Bombay plants merely cites Nimmo. Tt occurs in S. India and is common in Ceylon.— Distrib. India (W. Peninsula) ; Ceylon.
