4 pairs, also faint but visible, at right angles to the midrib, straight to 

 join an intramarginal nerve covered by the marginal thickening ; petiole 

 thick, very short. Umbels axillary, on stout peduncles "75 to 1"5 in. 

 long, which end in a thickened rachis of cushion-like bracts often -25 in. 

 long ; pedicels slender, -25 to -35 in. long ; buds globose ; flowers white, 

 usually tinged with yellow, scented. Calyx rotate, membranous ; lobes 

 as long as tube, -025 in. long, obtuse ; scales minute. Corolla -25 in. 

 in diam. when spread out, pubescent or scurfy within ; lobes trian- 

 gular, recurved. Corona membranous, of 5 processes, forming a concave- 

 sided cone, the lower lobe of each process spreading or upcurved, ovate, 

 the upper lobe ovate-acute, exceeding the anther. Staminal-cohmm 

 short ; anthers minute with very thin membranous acute appendages ; 

 pollen-masses oblong-falcate, reticulate, compressed, attached by erect 

 thickened cup-shaped caudicles to the small pollen-carriers. Style-apex 

 rather deeply lobed; tip conical. Follicles smooth. Dene, in DC. Prodr.

12. HoYA DiVEESiFOLiA, Blume Bijdr. 1064 (1826). A climbing 

 glabrous shrub ; branches flexuous, smooth, brown ; branchlets paler ; 

 the bark very thin. Leaves fleshy, very thick ; broadly elliptic or 

 obovate, obtuse or apiculate at apex, rounded at base ; both surfaces 

 glabrous, dull ; margins recurved ; 2 to 4 in. long, 1-5 to 2"5 in. broad ; 

 nerves only visible w^hen dry, midrib broad ; main nerves about 4 to 

 6 pairs, rather irregular, at about 60° with the midrib, soon branching ; 

 reticulations very indistinct ; petiole '25 to -5 in. long, thick. Umbels 

 many-flowered, on stout thick -25 to "75 in. long tubercular rachises at 

 the ends of very thick -5 to 2*5 in. long peduncles, which are lateral one 

 to each pair of leaves ; pedicels slender, -5 in. long ; buds flattened with 



5 rounded angles ; flowers "25 to '35 in. broad, white or rose-coloured 

 with pink corona (yellowish-white (Maingay)). Calyx membranous ; 

 lobes elliptic-obtuse, usually ciliate at the tips, '075 in. long ; scales 

 apparently none. Corolla glabrous without, puberulous within ; lobes 

 cordate-acuminate. Corona of 5 processes attached to the bases both 

 of the staminal- column and of the corolla-tube ; lower lobe of each pro- 

 cess orbicular or ovate, concave above and with a small central boss, 

 2-winged below, the wings connivent ; upper lobe erect, triangular-acute, 

 shorter than the anther-appendages. Staminal-cohimn very short ;
