V. s. in herb. Mus. Brit., Madagascar (Thompson) ; in herb. 
De Cand. ^ , Bourbon (ex hb. Linn, fil.) ; in herb. De Boissier, 
Bourbon (e Mus. Par.) ; in herb. Hook. & $ , Madagascar, 
(Blackburn). 
This species may be recognized by the large size of its nearly 
orbicular leaves, with a deep^ rounded basal sinus, upon eldn- 
gated petioles, and by the shortness of its spicated $ racemes. 
The leaves in the Madagascar specimens are 5-5^ inches long, 
5— inches broad, on a petiole 4 inches long, inserted Inline within 
the margin of the narrow rounded basal sinus, which is 9-1 1 lines 
deep. In the Bourbon plants they are 4 inches long, 4 inches 
broad, on a petiole 2^-3^ inches long, the basal sinus being 
nearly 1 inch deep. The panicles are 1-1 ^ inch long, the 
filiform peduncle 9 lines long, the primary branches 3 lines, the 
secondary 1 line, and the pedicels short ; the flowers are small, 
the sepals nearly orbicular, and marked with oblique interrup- 
tedly dotted lines, and pilose outside. The axillary ? racemes are 
3 inches long, with a slender rachis furnished with bracts spring- 
ing from the base upwards at intervals of about 3 lines, which 
are 2-3 lines in diameter, and each encloses six flowers upon long 
pedicels, which lengthen considerably with the growth of the 
ovaries; in the lower axil of the specimen there is a similar 
raceme, 10 inches long, upon a. slender rachis naked towards 
the base, which at the distance of 1| inch throws out a leaf 
2 inches in diameter, on a petiole inches long, and at a fur-
