on stout (-25 in.) rachises with small tubercles at the ends of rather long 

 (1-5 to 4 in.) slender peduncles ; pedicels slender, -5 to '75 in. long ; buds 

 hemispheric, 5-angled, flattened above, '25 in. in diam. Calyx small ; 

 lobes ovate, ciliate, membranous, glandular, recurved, "03 in. long. 

 Corolla "5 to -6 in. in diam. when open, glabrous without, puberulous 

 wnthin ; lobes ovate-acuminate, "2 in. long. Corona of 5 processes more 

 or less upturned ; lower lobes ovate, thick, very obtuse at tip, with a 

 raised ovate ring above and deeply cleft valves below ; upper lobe 

 shorter than the anthers, erect, acute. Staminal-column short ; anther- 

 cells slightly divergent ; appendages scarious, acuminate ; pollen-masses 

 thick, oblong, straight on inner side, attached by short caudicles embracing 

 their base to the rather large conical pollen-carrier. Style-apex 5-lobed, 

 acute at tip. Follicles (immature) 1 or 2, very slender, narrow ; peri- 

 carp very thin, smooth. Seeds small, oblong, truncate at tip with a 

 "75 in. long coma. 



Penang : John Scott. Peeak : Scortechini 464, 1557. 



John Scott's specimen has rather thinner leaves, but this is probably only due to 

 youth. His specimen bears no flowers, only young fruit, so we think it best not to 

 couple his name with the species. 



9. HoYA CAUDATA, Hook. f. Fl. Br. Ind. IV. 60 (1883). A twining

 sparsely papillose ; margins corrugate and recurved ; 3 to 7 in. long, 

 2 to 3 in. broad ; midrib slender ; main nerves 3 to 4 pairs, distant, 

 arching, very faint ; reticulations not visible ; petiole up to "25 in. long, 

 very thick, so thick as to appear globose. Umbels many-flowered on a 

 •5 to 1 in. long tuberculate rachis at the end of a thickened 1 in. long 

 peduncle ; pedicels "5 in. long, filiform ; flowers white suffused with 

 pink. Calyx very membranous ; lobes linear-lanceolate, glabrous, "05 to 

 •075 in. long. Corolla -5 to -75 in. in diam. ; lobes ovate, long caudate- 

 acuminate, silvery-pilose within. Corona fleshy ; lower lobes horizontal, 

 elliptic-ovate, the broadest end outwards, concave above ; the upper 

 lobe produced in a long erect subulate spur shorter than the anther- 

 tips. Staminal-column short ; anther-wings straight ; appendages mem- 

 branous, long caudate-acuminate ; pollen-masses flattened, oblong, trun-
