This most resembles a small P. plectranthoides, the bracts imbricating over the 

 flowers in the young spikes, but spikes and narrower bracts are much smaller, and the 

 whole plant when pubescent is never hoary. In its usual glabrous form it is a very 

 distinct plant. The leaves vary much in shape and cutting of the margin, and attain 

 9 inches in length, and are sometimes velvety beneath. The stem and branches are 

 usually dark purple, but not constantly. Calyx in. long, narrow, usually purplish. 

 It is difficult to distinguish some states of this from P. Heyneanus. Bentham says 

 that his var. Jacquemontii is almost intermediate between P. parviflorus and gldber 

 it has more glabrous leaves and villous spikes. 



7. P. glaber, Benth. in Wall. PL As. Ear. i. 31, Lab. 154, and in 

 DC. Prodr. xii. 152; erect, branched, glabrous or sparsely hairy, leaves long- 

 petioled ovate or ovate-lanceolate acuminate doubly-toothed or -serrate, 

 whorls small subglobose dense-fid, continuous in slender ciliate spikes, bracts 

 ovate much shorter than the very small calyx, calyx- teeth triangular 

 shortly ciliate. Wall. Cat. 1533.

Habit of P. parviflorus, but spikes more slender, bracts smaller, and calyx only 

 fa in. long, obovoid, with shortly ciliate teeth. Stem and branches green or purple, 

 sometimes very dark. 



ff Whorls usually separate, forming interrupted spikes (except P. Pat- 

 chouli, var. suavis). 



8. P. tuberculosus, Bentk. in Wall. PI. As. Ear.i. 31, Lab. 154, and 

 in DC. Prodr. xii. 152; stout, erect, branched, scabrid with stellate hairs, 

 leaves long-petioled ovate or deltoid-ovate acuminate doubly toothed, base 

 cuneate, whorls small subglobose many-fid, distant or separate on the long 

 slender panicled spikes, bracts scabrid oblong shorter than the small scabrid 

 obovoid calyx, calyx-teeth short triangular ciliate. 



TROPICAL HIMALAYA, alt. 1-5000 ft. j from Nepal, Wallich, to Bhotan, Clarke. 

 Stem and branches woody, terete, striate. Leaves 3-5 by 1^-3^ in., scabrid on 

 both surfaces. Spikes 7-10 in'. Calyx T ' in. Corolla twice as long, purple. 



9. P. Patchouli, Pelletier in Mem. Soc. Sc. Orleans, v. 5, ivithfig.; 

 erect, branched, pubescent or glabrate, leaves long-petioled ovate acute 

 acuminate or obtuse crenate or simply or doubly toothed or incised, base 

 cuneate, whorls subglobose many- and dense-fid, distinct or subconfluen't on 

 the slender pubescent or tomentose panicled spikes, calyx pubescent or 

 to'mentose, teeth triangular ciliate. Benth.. in DC. Prodr. x*'-. 153 ; Dalz. 4*
