1. V. ovatum (ovate leaves), Benth. Fl. Austr.'iy. 330. A rather slender 

 twiner, glabrous or the inflorescence minutely pubescent. Leaves on slender 

 petioles, ovate, obtuse, acute or shortly acuminate, rounded or cordate at the 

 base, 1 to 2 or rarely Bin. long. Umbels usually 2 at some distance from each 

 other on a slender peduncle, the flowers often exceeding the leaves. Pedicels 

 3 to 6 lines long. Calyx-segments about 1 line long; ovate, thin. Corolla 

 spreading to about 3 lines diameter, deeply divided into narrow ovate lobes. 

 Corona-segments very broad, almost orbicular, obtuse or very shortly acuminate, 

 rather shorter than the anthers, shortly adnate at the base along the centre. 

 Pollen-masses small, obovoid. .

2. V. elegans (elegant), Benth. Fl. Austr. iv. 330. A tall glabrous twiner. 

 Leaves on slender petioles, ovate, acute or mucronate, not cordate, rather fleshy, 

 penniveined, 1 to 2in. long, the upper ones sometimes narrow. Flowers few, 

 in clusters or umbels on forked or diohotomous peduncles often longer than the 

 leaves. Pedicels ^in. long or more. Calyx-segments ovate, very small. Corolla 

 pure white (WooUs), spreading to 5 or 6 lines diameter, very deeply divided into 

 oblong-lanceplate lobes, slightly pubescent inside. Corona-segments broad, 

 nearly the length of or rather longer than the anthers, abruptly acuminate, the 

 point incurved over the gynostegium. Pollen-masses oblong, pendulous but 

 attached below the top. 



Hab.: Recorded for Queensland by F. v. Mueller. 



3. V. carnoi^ni (fleshy leaves), Benth. Fl. Austr. iv. 331. Quite glabrous, 

 trailing or twining and rather slender. Leaves oblong oblanceolate lanceolate 

 or linear, obtuse mucronate or acute, rather thick and almost veinless, 1 to 2in. 

 long, narrowed into a short petiole. Flowers yellowish-green, in simple umbels 

 or very short racemes, on peduncles usually under ^in. long, the pedicels rather 

 longer. Calyx-segments narrow, acute, about IJ line long. Corolla deeply 

 divided into narrow acuminate lobes of 3 to 3|- lines. Corona- segments lanceolate, 

 acuminate, longer than the anthers. Pollen-masses oblong, small. Follicles 

 rather broad, acuminate, 2 to Bin. long. — Oxystelma carnosum, R. Br. Prod. 462 ; 

 Dene, in DC. Prod. viii. 543.

4. V. leptolepis (slender scales), Benth. Fl. Austr. iv. B31. A twiner, 

 quite glabrous or the inflorescence minutely pubescent. Leaves on long petioles, 

 broadly cordate-ovate, acutely acuminate, 1^ to 2Jin. long. Flowers small, 

 in irregular loose cymes or peduncles usually exceeding at least the upper 

 leaves. Calyx-segments about 1 line long, oblong, ciliolate. Corolla spreading 

 to rather above 2 lines diameter, divided to below the middle. Corona-segments 

 lanceolate, tapering into a subulate-acuminate ligula, more than twice as long as 

 the anther. 



Hab.: Mount Elliott, FiteaJan ; Elliott Eiver, Bowman. 

 The foliage is like that of several Cynaneha. —Benth. 



5. y. pachylepis (corona-scales thick), Bail. Bot. Bull. viii. A stout 

 ferruginous climber. Leaves rotund-ovate, apioulate, the base prominently 

 cordate, B to 5in. long, 2^ to 4in. broad ; petioles slender, 1 to l^in. long, 

 clothed as well as the principal veins with short brown hairs, the lamina nearly 

 or quite glabrous on both sides. Flowers cream-coloured, fragrant, in pubescent, 

 axillary umbels ; peduncle about lin, long, the pedicels not exceeding 3 lines! 

 Calyx- segments much overlapping, very broad, nearly orbicular, 2^ lines long,
