lobes acute or acuminate, incurved and connivent or cohering at the tips, 

 valvate in the bud. Corona inserted on the gynostegium, campanulate or 

 rotate at the base, with 10 or 15 lobes in 2 rows' (or rarely only 5); tlie inner 

 ones usually longer acuminate and connivent over the gynostegium. Anthers 

 without any termiiial membrane. Pollen-masses 2 to each anther, erect or 

 incurved. Stigma obtuse. — Stems usually twining from a tuberous rhizome. 

 Leaves membranous or fleshy. Flowers often few and rather large, iu 

 axillary or interpetiolar cymes or umbels. 



A considerable genus, widely spread over tropical Asia and Africa, although rare iu the 

 ladiau Archipelago. The only Australian species is one of t

 few in tlie Australian one, in a shortly-branched cyme sometimes contracted 

 into an umbel, the common peduncle usually longer than the petiole, the

 Imes long. Corolla-tube 1 in. long, including the campanulate throat, which 

 spreads to J in. diameter ; lobes shorter than that diameter, broad, acute, 

 erect, arcuate and cohering at the tips. Corona loosely campanulate at the 

 base, with 10 short lanceolate or oblong outer lobes in pairs usually sprinkled 

 with a few long hairs, and 5 inner linear ones, twice as long as the outer ones 

 and connivent over the gynostegium or cohering at the tips. Follicles (in 

 the Philippine Island plant) very long and linear.— F. Muell. Fragni. v. 159. 



Queensland. Near Somerset, Cape York, Jardine, a single specimeu in Herb. F- 

 Mueller. Also m the Philippine Islands. The glabrous stems, cordate leaves, and small 

 calyx-sesrmerits, readily distinguish this species from all others in the Kew coOections. On 

 companng the gynostegium and corona of the Australian and Philippine specimens, I find 

 no aiiterence ; the outer corona-lobes are very slightly hairy in both, although the hairs are 

 sometimes reduced to 1 or 2 to each lobe. The Ja/anese plant figured as C. Cuwir>gma

 ana acummate and in the much more clavate inner corona-segments, and appears to be tte

Flowers regular. Calyx free, with 4 or 5 teeth lobes or segments, very 

 rarely reduced to 2 or in a very few species 6 or 7. Corolla with 4, 5, or,m 

 genera not Australian, more than 5 lobes, valvate contorted or otherwise im- 

 brica e in the bud. Stamens as many as corolla-lobes, alternate with them, 

 inserted m the tube or very rarely, in a genus not Australian, reduced to 1 ; 

 anthers 2-ceIled, the cells opening loujitudinally. Ovary free, 2-celled or 

 very rarely 3- to a-celled or imperfectly divided ; style single or separating 

 nto 2 at the base, with an entire or 2-lobed stigmatlc summit; ovules 1 or 

 mo e in each cell of t^ie ovary or to each placenta. Fruit a berry or capsule, 

 beeds albummous Embryo straight, often oblique, with leafy or small co- 

 tyledons.-Trecs shrubs climbers or rarely herbs! Leaves opposite, usually 

 connected by interpetiolar stipules or at any rate by a raised line.
