624 cxn. LABIATE. (J. D. Hooker.) [Plectranthus. 



Stem 1-2 feet. Leaves l-2 in., narrowed into the petiole, rather coriaceous, 

 nerves oblique. Fruiting calyx in. Corolla and nutlets not seen. The 

 specimens are hardly fit for description, but the species is too remarkable to be 

 passed over. 



DOUBTFUL SPECIES. 



P. PATCHOULI, Clarke mss. ; tall, erect, branched, hirsutely tomentose, leaves 

 petioled ovate-cordate crenate-toothed, cymes branched, flowers subsecundly sub- 

 sessile on the branchlets of a loose panicle, calyx-teeth subequal, corolla-limb 

 subclavate with a large incurved cymbiform obtuse lower lip and shorter narrow 

 upper lip. 



ASSAM; Jenkins (Herb. Calcutt.). KHASIA MTS. ; Johra, alt. 4000 ft, cult., 

 Clarke. 



Stem stout, branched. Leaves 2-3 in., hairy on both surfaces. Cymes panicled, 

 irregularly branched; bracts small, leafy; pedicels T ' n in. or 0. Calyx hardly 

 2-lipped, teeth acute. Corolla 1 in., tube slender, upper lip much shorter and 

 narrower than the saccate obtuse lower, which is much larger than the tube. " This, 

 I am told, is the true Patchouli plant, and has the true scent, which Pogostemon 

 Patchouli has not." C. B. Clarke. I have seen no fruit, and the inflorescence is 

 very peculiar ; it may not be a Plectranthus. 



P.? MONTANUS, Benth. in Wall. PL As. Rar. ii. 17, and in DC. Prodr. xii. 

 60; Wall. Cat. 2747; densely tomentose, stem short very robust, leaves shortly 

 petioled ovate or rounded crenate very thick rugose, racemes dense-fld. pyramidate, 

 branches very thick ascending, whorls close set but not confluent, flowers sessile or 

 pedicelled, calyx ^ in. hemispheric with 5 triangular subacute teeth, nutlets suborbi- 

 cular polished pale. Mysore; at Nundydroug, Klein, Herb. Rottler. Habit of 

 P. coleoides, but calyx very different. The specimens are very imperfect, and have 

 no corolla. 



HTSSOPUS LOPHANTHOIDES, Ham. in Don Prodr. 110, referred to P Gerardia- 

 nus by Bentham, can hardly be that plant ; a specimen of it from Hamilton more 

 resembles P. striatus, being very pubescent. It may, however, be a hairy form of 

 P. Gerardianus. 



OCIMUM DBNSIFLOBUM, Roth Nov. Sp. 275, doubtfully referred by Bentham to 

 P. rugosus, must be a very different plant, according to the description. 



P. BOTUNDIFOLIUS, Spreng. Syst. ii. 690; Benth. Lab. 34, and in DC. Prodr. 

 xii. 65 ; Grah. Cat. Bomb. PI. 148. Coleus ? rugosus, Benth. in Wall. PI. As. Rar. 

 ii. 15. Germania rotundifolia, Poir. Diet. ii. 763. Nepeta uiadagascariensis, Lam. ? 

 Diet. i. 712. Kurka, Rheede Hort. Mai. xi. t. 25? A reputed native of Mauritius 

 and Coromandel ? The last habitat is no doubt founded on the supposed identity of 

 the Mauritian with the plant figured by Rheede, which represents a flowerless tuberi- 

 ferous herb which has not been identified. Local botanists should be able to discover 

 what Rheede's plant is. 



9. COLEUS, Lour. 



Characters of Plectranthus, but filaments combined below into a sheath, 

 around the style. Species about 50, Tropical African and Asiatic, and one 

 Australian. 



* Calyx-throat villous within. 



1. C. spicatus, Benth. in Wall. PI. As. Ear. ii. 15, Lab. 49, and in 

 DC. Prodr. xii. 71; stem very stout villous with long spreading hairs or 

 glabrate, leaves subsessile obovate ovate or orbicular glabrous fleshy entire 

 or crenate, floral large concave deciduous, whorls in a dense cylindric spici- 

 form villous thyrse, upper calyx-lip very broad truncate. Wight lc. 

 t. 1431 ; Wall. Cat. 2729. C. Heynii, Benth. Lab. 50, and in DC. 1. c. C.
