Flora of the Malayan Peninsula. 
the whole minutely rusty-pubeseent, 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. 
Tenasserim : 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 
Pothos in appearance. Leaves few, coriaceous, entire or denticulate, 
sessile orpetiolate, the petiole often dilated, main leaf-nerves very many, 
at right angles to the midrib. Flowers 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.

1. Labisia pumila, Benth. & Hook. f. Gen. PI. II. 645 (1876). A 
semi-herbaceous undershrub, with rooting stems and leaves not jointed 
at their insertion but decurrent into them. Leaves bluish-green, 
elliptic-lanceolate, acuminate, narrowed at the base, and more or less- 
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 
to the midrib, parallel, slender, anastomosing towards the margin, and
