Flora of the Malayan Peninsula. 569 



A climbing (probably epiphytic) shrub ; branches very stout, smooth, 

 lenticellate, giving out slender rootlets occasionally. Leaves very thick, 

 fleshy ; ovate or oblong-ovate, acute at apex, rounded or cordate at base 

 often slightly peltate ; glabrous on both surfaces, dull when dry ; mar- 

 gins strongly recurved, shining ; 5 to 10 in. long, 3 to 7 in. broad ; 

 midrib w^ith a gland at the base ; nerves 3 to 5 from the base, connected 

 at intervals by few irregular cross-nerves ; reticulations not otherwise 

 visible ; petiole very stout, -25 to "5 in. long, articulated to a thick 

 shining cup-like base at the node. Umbels racemose, on thick, pitted, 

 up to 1 in. long, tubercular rachises at the end of stout 1 to 2 in. long 

 peduncles, which are solitary or fascicled in the leaf-axils or at the nodes 

 of very long (sometimes 5 ft. !) flowering branches ; pedicels very 

 slender, puberulous, -25 in. long ; buds flattened, 5-angular ; flowers 

 very small, grey, "35 in. broad when open, '15 with the lobes closed. 

 Calyx minute, membranous ; lobes ovate, acute, "3 in. long. Corolla 

 sm.all, rotate, pubescent within ; lobes ovate, at first incurved over the 

 staminal-column, afterwards spreading. Corona of 5 membranous pro- 

 cesses, each consisting of an ovate lower horizontal or slightly upcurved 

 lobe concave above and deeply grooved below, the tip apiculate re- 

 curved, and an upper shorter erect lobe with acute tip and a channel 

 behind. Staminal-column veicj short ; anther-cells divergent ; appen- 

 dages membranous, acute ; pollen-masses oblong-falcate, pellucid on the 

 outer margin, attached by short thick caudicles to the rather large 

 3-lobed pollen-carriers. Style-apex sharply 5-angled, conical-apiculate. 

 Follicle 1, very slender, 4 to 4-5 in. long, "2 in. broad ; pericarp thin, 

 puberulous. Seeds oblong, acute at base, truncate at tip, "25 in. long, 

 bearing a white silky coma 1 to 1"25 in. long ; cotyledons thick, ovate- 

 oblong, -1 in. long ; radicle as long and broad as cotyledons, flattened.
