 Distrib. 2857-8-9) ; EASTERN PENINSULA, from the Concan southwards ; CEYLON. 



A common and variable plant, probably a variety of 0. Mungos, but smaller, more 

 pubescent, with longer stipules, usually longer subulate calyx-teeth, and setaceous or 

 filiform bracteoles, less spreading cymes, and smaller capsules. The following seem 

 referable to it, and are scarcely distinguishable. 



VAR. 1. Harrisiana, Wall. Cat. 6236; slender, rooting below, leaves 1^-2 in. 

 'broadly ovate often obtuse base often rounded or even subcordate glabrous above, 

 cymes small. Wight Ic. t. 1162 (Harrisonii). Mysore, Heyne, &c.

 acuminate at both ends with minute scattered hairs above, cymes few-fld. 0. prostrata,

VAR. 3. decumbens, Gardn. Mss. ; stems decumbent often much branched, leaves 

 l^r-4 in. obtuse or acute narrowed at the base glabrous above, cymes contracted, 

 corolla very short. Ceylon, alt. 5-6000 ft. ; abundant in the Eastern Peninsula and 

 Tenasserim. 



VAR. 4. argentea, Wall. Cat. 6229 (sp.) ; more glabrous, leaves l|-4 in. ovate or 

 narrowly lanceolate usually white beneath and sometimes along the midrib above 

 glabrous or with short hairs above, cyme and flowers glabrous. Khasia Mts., Sylhet, 

 Chittagong, Mergui, Ceylon, Nilgherries, and other Peninsula Mts. 



VAR. 5. merguensis ; like var. argentea, but cyme and corolla very tomentose, leaves 

 either glabrous or with scattered short hairs above. Mergui, Nilgherries. 



3. O. trichocarpa, Bl. Bijd. 977; stem erect branched, leaf-nerves 

 beneath and cyme densely pubescent, leaves ovate acute or acuminate glabrous 

 or with scattered hairs above, stipules filiform from a subulate base, cymes small 

 sessile or shortly pedimcled dense-flowered tomeutose, bracteoles 0, calyx-teeth 

 subulate, corolla ^ in. puberulous, tube narrow, capsules pubescent. O. hispidula,

This may be only a form of Harrisiana, and if so this latter name must give place 

 to Blume's. I see little but the pubescent capsules whereby it is to be distinguished. 



4. O . ocliroleuca, Hook. f. ; shrubby, glabrous except the cymes, leaves 

 large quite glabrous beneath, stipules lanceolate 2-fld. caducous, cyme-branches 

 spreading, bracts or minute and caducous, calyx-teeth very short, corolla 

 cylindric fleshy mouth not dilated, lobes short recurved pubescent within with a 

 short dorsal spur below the top not keeled at the back, capsule glabrous.
