Branches many and straggling from the woody stock, stout, cylindric, 6-8 in. 

 high. Leaves J in. long, tomentose on both surfaces, base rounded ; petiole ^i in. 

 Racemes 3-4 in., stout or slender; whorls rather distant, 2-4-fld., floral leaves 

 minute. Calgco pubescent, throat with long hairs, fruiting ribbed, 2 lower lobes 

 rigid, subulate. Corolla about \ in. long. Nutlets oblong, obscurely reticulate, 

 brown, nearly smooth. — I suspect that the Ceylon habitat is an error.

Branches 6-12 in., many, ascending from a stout woody stoolr. Leaves ^-2 in., 

 obtuse or acute, scentless, base cuneate entire and narrowed into a petiole ^-J the 

 length of the blade. Bacemes long or short, stout or slender ; floral leaves minute ; 

 flowers j^ in. long. Corolla white. Fruiting calyx as long as the pedicel, \-\ in. 

 long, deflexed ; lower teeth subulate or aristate. Nutlets subglobose, compressed, 

 pale, nearly smooth. — With difficulty distinguished from states of Ocimum adsoendens, 

 the calyx being nearly identical. Roxburgh's flgare of 0. inodorus is this plant, but 

 his description refers to some other with cordate rugose leaves and cordate bracts. 



3. O. tomentosus, Benth. in Wall. PI. As. Bar. ii. 14, Dab. 27, and 

 in DC. Prodr. xii. 51 ; tomentose, pubescent or glabrate, sometimes viscid, 

 leaves petioled ovate, base rounded cuneate or cordate, racemes elongate, 

 bracts ovate, 4 lower calyx- teeth awned, corolla from half as long to thrice as 

 long as the calyx, tube subincurved, nutlets subglobose compressed pale 

 brown nearly smooth.

A most variable plant. I am quite unable to find any characters whereby to define 

 strictly the following forms. The O. ruhioundus is distinguished by the long sessile 

 or snbsessile leaves.
