the whole minutely rusty-pubescent, pedicels slender. Calyx-lobes triangular acute 

 •03 to '05 in. long, ciliate ; tube as long as lobes or somewhat shorter. Corolla-lobes 

 oblong-spathulate, -1 in. long, ciliate, minutely pubescent, sparsely gland-dotted. 

 Stamens longer than corolla-lobes, -15 in., anthers oblong, cells parallel, not warted 

 behind at the insertion of the long exsert filaments which spring from close to the base 

 of the corolla-lobes. Ovary ovoid-conical, style short curved, stigma minute. Berry 

 unknown. 



Tenassebim : at Moolyet, 5,000 feet, G. Gallatly No. 407. Gamble 

 No. 7906 from Mianimukh, Chittagong Hill Tracts, without flowers or 

 fruit, is probably this species. 



4. Labisia, Lindl. 



Small shrubs, with a creeping rhizome and erect stem, resembling 

 PotJios in appearance. Leaves few, coriaceous, entire or denticulate, 

 sessile or petiolate, the petiole often dilated, main leaf-nerves very many, 

 at right angles to the midrib. Flotoers hermaphrodite, minute, pink, in 

 axillary spike-like panicles, bracts very small. Calyx minute, 5-lobed. 

 Corolla 5-lobed, lobes ovate, induplicato-valvate in bud ; tube very short. 

 Stamens 5, wrapped in the corolla-lobes ; filaments very short ; anthers 

 ovoid, introrsely dehiscent, no staminodes. Ovary globose, attenuated 

 into a short style ; stigma small ; ovules few, immersed in a globose 

 central placenta. Fruit small, globose, red, 1-seeded. Seed globose, 

 hollowed at the base ; albumen smooth ; embryo cylindric transverse. 

 — DiSTRiB. About 4 species, all of the Malay Peninsula and Archi- 

 pelago.

 decurrent on the petiole ; crenately toothed, or sometimes nearly 

 entire ; blade 5 to 8 in. long by 1 to 2*5 in. broad ; midrib thick, often 

 rusty-pubescent ; main-nerves extremely numerous, nearly at right angles
