12. Genianthus, Hook. f. 



Twining shrubs. Leaves opposite. Flotvers small, in clusters in 

 axillary, subsimple or clicliotomously branched, often racemose or spicate 

 cymes. Calyx very small, 5-fid ; scales 5, between the bases of the 

 lobes within. Corolla rotate ; tube short ; lobes narrow, spreading or 

 recurved, villous on the inner face, valvate. Corona of 5 often lobed 

 processes adnate to the back of the staminal-column and often longer 

 than it. Staminal-column short ; anthers erect ; appendages short, 

 around the style-apex and shorter than it ; pollen-masses 2 in each cell, 

 rounded, granular, on a small curved pollen-carrier without caudicles. 

 Ovary of 2 carpels ; style thick ; style-apex 5-angled below, tip capitate 

 or long and slender. Fruit of 2 divaricate, thickened, usually obtuse, 

 follicular mericarps ; testa thickened, often tomentose. Seeds large, 

 flattened, winged, with a long silky coma ; cotyledons small ; radicle 

 cylindric. — Disteib. About 6 species, of India and Malaya. 



Leaves more or less lanceolate, glabrous or nearly so beneath : — 

 Leaves usually under 3 in. long, shortly acuminate ; cymes 

 rarely up to 4 in. long, with close flower-clusters . . .. 1. G. Maingayi. 



Leaves usually over 3 in. long, long-acuminate ; cymes reach- 

 ing 6 in. in length, with distant flower-clusters . . . . 2. G Ridleyi. 



Leaves elliptic-ovate or -obovate, ferruginous-tomentose be-

 Main nerves of leaves at about 50° with the midrib ; follicles 

 densely rufous-velvety . . . . . . . . 3. G. rufo-velutinus.

follicles glabrous . . . . . . . . 4. (?. Bluviei. 



1. Genianthus Maingayi, Hook. f. in Fl. Br. Ind. IV. 16 (1883.). 

 A slender climbing shrub ; branchlets brown, terete, the uppermost 

 purplish-pubescent ; nodes swollen. Leaves coriaceous ; obovate or 

 oblanceolate, shortly acuminate at apex, cuneate at base, greyish-green 

 when dry, the lower surface somewhat paler than the upper, both 

 slightly pubescent when young ; margins strongly recurved ; 2*5 to 3"5 

 in. long, 1'25 to 1*5 in. broad ; midrib prominent, with a gland at the 

 base, raised on the lower, impressed on the upper surface, as are the 6 

 to 7 pairs of main nerves which curve upwards to join a looped intra- 

 marginal nerve ; secondary nerves few ; reticulations few, irregular, 

 rather broad ; petiole "25 to -5 in. long, twisted. Cymes in pairs from 

 the leaf-axils, up to 4 in. long, bearing clusters of sessile flowers 

 racemosely arranged ; rachis angular, purplish-pubescent ; bracts 

 minute, ovate-acute ; buds clavate ; flowers white with a reddish tinge. 

 Calyx purplish-pubescent without ; lobes oblong, obtuse, '05 in. long,
