APOCYNACEJE (H. F. Wernham) 63 
concavis acutis persistentibus majusculis ; calyce late campanulato 
extus glabro lobis ovatis subacutis tubum vix aequantibus ; 
corollae tubo contorto extus glabro infra medium et iterum infra 
lobos valde constricto lobis oblongo-lanceolatis glabris acutiusculis 
tubum excedentibus. 
Oban ; n. 2071. 
Leaves 17-22 cm. long, 5-5°5 em. broad; petioles 1:7 cm. long; 
lateral veins 8-10 pairs, Peduncles to 17 em. long, about 4-flowered. 
Bracts about 1 em. long, and the same width in the broadest part. 
Calyz-tube T mm. long and rather more in width ; lobes variable, the 
average about 5 mm. x 4mm.  Corolla-tube 1*8 cm. long, the lower 
constriction 5 mm. above the base, 4 mm. wide in the median dilated 
part; lobes 1*6 em. or more long, and about 2*5 mm. broad. 
The nearest affinity seems to be with V. Zenkeri Stapf, but the 
difference is clearly seen in the larger leaves and longer petioles, and 
in the shape and size of the corolla-lobes and longer tube of the 
new species.

The leaves vary a good deal in size; theaverage for the adult leaves 
is about 9 em. long, 3:5 cm. wide, the largest being 15 em. x 5*5 cm. 
Secondary veins 10-12 pairs. Petiole 6-8 mm. long. Inflorescence 
3-4 cm. wide. Peduncles 2-8: 5 em. long at first, at length attaining 
6-7 cm. Bracts 8 mm. long, boat-shaped. Floral pedicels 7 mm. 
long. Calyx-tube 3-4 mm. long; lobes about the same length, and 
as much as 3 mm. wide at the base. Corolla-tube cream-coloured, 
7 mm. long, the pale primrose lobes as much as 4 mm. long. 
Related to V. diplochlamys K. Schum., from which it differs in its 
more complete glabrousness, the longer floral pedicels, the smaller 
calyx and much smaller corolla, with lobes considerably shorter than 
the tube.
