1. MiCROT(ENA CTMOSA Prahi ; minutely tomentose, leaves widely 

 ovate-acute base snbcordate margin crenate-dentate, cymes rather lax, 

 calyx teeth triangular, galea throat below 2-auriculate rather longer 

 than tube, lateral lobes of lip ovate-rotund thrice exceeding central 

 narrowly elliptic, nutlets very minute. — Microtoena cymosa Prain in 

 Hooh., Icon. Plant, xix, t. 1872. — Microtaena cymosa Forbes 8f Hemsl.y 

 Jour. Linn. Soc. xxvi, 306 and xxviii, 116. — Goraphostemma insuave

 Hook. /., Flor. Brit. Lid. iv, 624 and Jour. Linn. Soc. xxv, 58. 



Assam: Naga Hills, Jenhins ; Manipur, Clarke; Khasia hills at 

 Sohra 4000, cult., Clarke; Shillong 5000, cult., Mann. Burma; Shan 

 hills, at Fort Stedman, 3000, Collett n. 921. Distrib. S. China. 



Stems 40 — 100 cm., lower branches 15 — 20 cm. petioles 2 — 3 era. 

 long, laminae 4 — 7 cm. long 3 — 5 cm. wide, hairy on both surfaces, cymes 

 sometimes loosely paniculate irregularly branched, calyx 25 mm, (tube 

 2 mm.), corolla 14 mm. (tube infundibuliform 6 mm., upper lip 8 mm.), 

 pollen grains minute oval smooth, nutlets 1"25 mm. — The cultivated 

 plant smells very strongly of Patchouli, much more so than does the 

 Patchouli plant of commerce, but it is only grown as a curiosity; the 

 natives of the hills of Assam do not grow this plant or the true Patchou- 

 li plant, nor do they know or use the prepared article : the Shan hill 

 plant is devoid of smell.

 acute, base cuneate margin duplicate-crenate, cymes rather dense, calyx 

 teeth deltoid acuminate, galea throat entire half as long as tube, lateral
