An erect herb. Leaves 5 by 1^2 in. ; petiole \ in., usually pubescent. Racemes 

 in the Indian examples forming very compound, slender, terminal, lax panicles; bracts 

 minute linear ; pedicels often J-^ in. Sepals | in., linear-lanceolate. Corolla 

 glabrous, pink or whiteish ; cylindric base of the tube scarcely -^j in. ; lobes 5, ovate, 

 subequal. Stamens 2, with 2 minute linear rudiments. Capsule J in. ; base cylindric, 

 solid. Seeds 4 as of JEranthemum, but nearly smooth, scarcely rugose. — The Chinese 

 examples all differ from the Indian in their much simpler inflorescence. Bentham, in 

 allowing the genus 2 species in the Gen. PI., appears to think the Chinese plant 

 distinct, but in the Flora of Hongkong he had nnited them. 



Annnal herbs or very small shrubs, erect or procumbent. Leaves entire. 

 Maxemes axUlary and terminal, lax, often compound subpanicled, or dense 

 or subcapitate, sometimes reduced and 1-fld., frequently 1-sided ; bracts 

 small; bracteoles minute or 0. Sepals narrow. Corolla small, tubular, 

 2-lipped, white or pink with dark-purple lower lip, pubescent. Stamens 2 ; 

 filaments ciliate or setulose; anthers exserted, 2-celled; cells oblong, 

 parallel, muticous, subequal, base bearded. Ovary 6-12-ovulate, thinly 

 hairy ; style slender, tip minutely bifid. Capsule linear-oblong or elliptic, 

 compressed contrary to the septum, 6-12-8eeded. Seeds osseous, sub- 

 quadrate or oblong, not compressed, rugose-pitted, glabrous. — Endemic in 

 India ; the 17 species being very closely connected, and identical as to form 

 and colour of flower, and as to seeds. 



* Capsule linear, thrice as long as broad. 



f Racemes elongate often loosely suhpaniculate, lower flowers distant.

Throughont India from Lucknow and Assam to Ceylon (probably introduced in 

 some of the northern stations).— Distbib. Cultivated in the E. and W. Indies. 



An erect annual, 1-3 ft. ; stems quadrangular, base not pubescent. Leaves 2| by 

 i-f in., narrowed at both ends, never spathulate, ovate at base, paler beneath ; petiole 

 0-J in. Racemes 1-4 in. ; pedicels 0-^ in. , distant, usually pubescent ; bract ^ig in., 

 linear ; bracteoles smaller or ; inflorescence mostly sympodal, the pedicel in the axil 

 of one of each pair of bracts suppressed. Sepals ^ in., linear-lanceolate, pubescent. 

 Corolla 4 in., 2-lipped for at least half its length, hairy ; white, spotted rose-purple. 

 Filaments hairy upwards. Ovary and base of style subglabrous or very thinly hairy. 

 Capsule I by J in., young slightly glandular-hairy, mature glabrous. Seeds subquad- 

 rate, osseous, rugose, without hairs or scales at any period, wet or dry, yellow or deep 

 brown. — Bentley and Trimen's figure is erroneous as to the seeds being hairy. Nees 

 and others have .doubted this being Roxburgh's Justicia paniculata, because Roxburgh 

 says the bracts are large ; but Roxburgh regards the reduced leaves at the base of 

 the racemes as bracts, and does not notice the true small bracts at the base of the 

 pedicels.
