pair of nerves extending beyond the middle of the leaf, the apex 
very shortly and abruptly acuminate, the acumen apiculate by the 
slightly excurrent midrib; lateral nerves above the basal one about 
3 on each side of the midrib, ascending at an angle of about 45°, 
slender, distinct, the reticulations rather distinct; petioles 2.5 to 
3 cm. lone; tendrils simple, usually or always attached with the 
petioles, rather rigid, up to 9 em. long. Panicles from the stems 
and branches below the leaves, pendulous, up to 60 cm. im length, 
the branches rather few, scattered, spreading, up to 17 cm. in 
length. Flowers racemosely arranged on the primary branches, 
solitary or in pairs, their pedicels about 3 mm. long. Male flowers
