576 Flora of the Malayan Peninsula. 



netted ; petiole very thick, -25 to -75 in. long, broad at the junction 

 with the blade. Umbels many-flowered, on -25 to 1 in. long rachises 

 with small tubercles at the ends of stout lateral peduncles 1 to 4 in. 

 long ; pedicels slender, -5 to '75 in. long ; buds flattened, -25 in. in diam. 

 Calyx papillose without ; lobes oblong, acute, "06 in. long ; no scales. 

 Corolla rugose without, puberulous within ; lobes cordate, almost 

 3-pointed, points acuminate, especially the end one. Corona of 5 shining 

 inflated processes ; lower lobe horizontal, ovate, sharply acute, concave 

 on the upper surface with a median ridge, 2-valved below ; upper lobe 

 on acute erect tooth, shorter than the anthers. Staminal-column short, 

 inserted on the tube of the corolla, wings of filaments ear-like ; anther- 

 cells divaricate ; appendages scarious, acuminate, incurved ; pollen- 

 masses flattened, oblong, truncate at top ; attached by short thick 

 caudicles to the 3-lobed rounded rather large pollen-carriers. Style- 

 apex membranous, 5-angled ; tip long conical. Fruit not known. 



Kedah : at Pulau Songsong, Curtis. Penang : Curtis ; at Pulau 

 Tikus, Biclley 9476. Peeak : at Maxwell's Hill, Bidley 5519. 

 Singapore : at Grange Eoad, Bidley 10358. 



To this species, also, probably belongs Curtis 2355 from Kwala Lumpor, Selangor, 

 which has, however, smaller leaves, but no flowers. 



19. HoYA PAEViPLORA, Wight Contrib. 37 (1834). A twining, slender, 

 epiphytic undershrub ; rooting on the stems and branches of trees ; 

 branchlets very slender, terete. Leaves thick, coriaceous; lanceolate, 

 acute both at apex and base ; glabrous on both surfaces ; margins 

 slightly recurved ; 2 to 4 in. long, -35 to "75 in. broad ; midrib slender, 

 obscure ; main nerves very faint even when dry, 5 to 6 pairs, very 

 acutely (about 10°) spreading from the midrib, the lowest pair even 

 more so ; reticulations not visible ; petiole about -15 in. long, thick. 

 Umbels many -flowered (30 to 40), racemose, lateral or terminal; peduncle 

 rather stout, 1-5 to 1'75 in. long, ending in a thickened strobilate rachis 

 often 1 in. long with minute imbricate bracts ; pedicels slender, -25 to 

 •5 in. long; buds globose, depressed; flowers many, about '15 to "25 in. 

 in diam., apparently white. Calyx membranous, very small ; lobes 

 ovate. Corolla rotate, revolute, villous within with unicellular soft 

 hairs ; lobes triangular. Corona of 5 membranous horizontally spread- 

 ing processes, forming a shallow cone ; lobes longitudinally folded, bifid 

 at apex. Staminal-column very short ; anthers connivent over the 

 style-apex, with very thin membranous appendages ; pollen-masses very 

 minute, flattened, oblong-truncate, attached by minute cup-shaped 

 caudicles to the triangular pollen-carriers. Style-apex with a conical 

 tip. Follicles very slender, 4 to 5-5 in. long, -2 in. broad ; pericarp thin.
