94 SOUTH NIGERIAN PLANTS 
Var. longissima. Cauda maxime elongata, saepe ternatim 
divisa, 20-25 cm. long, triente superiore usque ad 2-3 mm. diam. 
dilatata.

The upper part of the perianth-tube of this supposed variety is 
more curved than that of type specimens, otherwise except for the 
very long tails there seems no difference. As with the type, no leaves 
of this are to hand. The perianth is very pale green in colour with 
dark purple spots, and the hairs in the throat are pure white. The 
single fruit sent consists of two oblong portions (apparently the two 
halves, though the ends do not quite match), each 10 em. long and 
3 em. in diameter, deeply 6-suleate and in colour a dark brown; the 
seeds are cordate, palely shining and 1 cm. long.

|... Stem and leaves not seen, but certainly a twiner. Perianth dark- 
coloured and leathery when dry, traversed by several longitudinal 
nerves, reticulum not very plainly seen; utricle 2:5 cm. long, 
1:5 em. broad, projecting beyond the narrower lowest part of the 
tube; tube arching above, inside pilose with white hairs, 4:5 cm. 
long, 10 mm. broad at the base, i4 mm. at the middle, and 30 mm. 
immediately below the limb, mouth emarginate at the end opposite 
to that bearing the tails, its three teeth about 2 mm. long, tails very 
slender up to 20 cm. long, about "3 mm. wide, but distally widening 
to about 1 mm. Stalk of gynostemium 2 mm. long.  Anthers 
narrowly oblong, 3 mm. long. Branches of stigma with short 
incurved tails, nearly 3 mm. long. 
Nearly allied to the last, but the perianth of A. tenwicauda is 
larger, the utricle more prominent, the upper part of the tube more 
curved, the mouth wider, the place of the single tail is always taken 
by the three slender tails, and the anthers and styles are longer.
