 leaves, more veiny, and finely pubescent beneath, and, like the 

 calyx, canescent.

 brous ; stem erect, nearly simple ; leaves ovate, acute, coarsely 

 toothed, narrowed a long way at the base ; raceme loose, few- 

 flowered ; fructiferous calyx erect, campanulate, glabrous, equ- 

 ally 5-toothed. ^.? G. Native of Japan, Thunberg. This 

 differs from P. amethystoides in the narrower leaves, and simple 

 few-flowered raceme. 



Inflexed Plectranthus. PI. 



t Species doubtful whether belonging to the present genus. 



42 P. SALVIOIDES (Benth. lab. p. 45.) leaves ovate-oblong, 

 crenulated, running into the petioles at the base, and quite 

 entire, pilose on both surfaces, ciliated ; stem hoary from 

 reversed pili at bottom, but beset with glandular clammy villi 

 above, as well as the calyxes ; raceme terminal, simple ; bracteas 

 roundish-ovate, on short petioles ; lower lip of calyx (superior ?) 

 tridentate : middle tooth the smallest. Tf. . ? G. Native of the 

 East Indies. O'cymum salvioides, Heyne, in Roth. nov. spec,

 quadrangular, hoary. Calyx nerved, sub-bilabiate. Corolla 

 small, brownish purple, hardly one half longer than the calyx, 

 resupinate, villous outside. The inflorescence and form of co- 

 rolla is that of O'cymum, but the calyx is very different. It is 

 perhaps a species of Moschosma or PentJa. 



Sahia-like Plectranthus. PI.

 pedicels subumbellate ; leaves ovate-oblong, coarsely-toothed, 

 pubescent on both surfaces. If. . ? S. Native of Java, in 

 mountain marshes. Elsholtzia Javanica, Blum, bijdr. 825.

 corolla long, concave, almost quite entire : upper one arched,
