 Stems shrubby at the base, erect and slender (or the branches rarely elon- 

 gated and twining ?), minutely pubescent as well as the inflorescence and 

 young foliage. Leaves very narrow-linear, flat or with recurved margins, 

 contracted into a very short petiole, 3 to ,5 in. long. Flowers not numerous, 

 in shortly pcduncuLite interpetiolar umbels. Sepals almost acute, about | 

 line long. Corolla-tube rather shorter than the calyx, broadly campanulate; 

 lobes ovate-lanceolate, rather longer than the tube,'bearded inside below the 

 middle as well as the tube, and the throat almost closed with tufts of hairs 

 alternating with the lobes, but no scales. Corona none except obscure protube- 

 rances at the base of the gynostegiura. Stigma narrow-conical, longer than 

 the anthers.— Seem. Y\. Vit. t. 31.

Also in tlie Kiji Islands, if my identification is correct. Seemann's specimens Lave tlie 

 leaves not so loii^, and the peduncles shorter, or the umbels almost sessile. The corollas 

 are also described as more rotate and less hairy inside, but the Australian and Fiji plants are 

 otlicrwisc exceedingly similar. Our specimens from Fiji have no perfect corollas. 



Sect. III. Gongronema.— Corolla without scales in the throat. Corona 

 consistmg of 5 small glands or protuberances at the base of the gynostegium. 

 -Leaves with small glands at the base of the lamina on the upper side. 



6. G micradenia, Benih. A rather slender but tall twiner, minutely 

 but softly pubescent. Leaves obovate-oblong or elliptical, abruptly and 

 shortly acummate, mostly rounded at the base, becoming glabrous above 

 wlien lull grown, with 2 or 3 minute glands on the upper surface imme- 

 diate y above the petiole, 1 to 1^ in. long. Umbels small, sometimes 

 shortly developed into cymes, on short interpetiolar peduncles, solitary or 

 rarely opposite and axillary. Calyx-segments ovate, obtuse, not \ line loiij. 

 '-orolla-tube broad, as long as the calvx, slightly contracted at the throat but 

 without scales or hairs inside; lobes short, obtuse. Corona of 5 scarcely 

 promment small glands or protuberances at the base of the gynostegium. 

 otigma shortly and obtusely conical. Follicles acuminate, about 1 line long.
