4 SOUTH NIGERIAN PLANTS 



± 10 mm. long. Frivit with pedicel 2 -0-2 '5 cm. long, oblong, 

 5" 6 mm. diam. 



Differs from the type by the larger leaves, the flower-pedicels and 

 the longer outer petals. 



[Sepals bronzy-green, outside petals pale cream, inside shaded, 

 mauve at base.— P. A. T.] 



The petals of n. 1677 are somewhat narrower and more pointed.

Oban ; nn. 1246, 1323. 



Tree 20-25 metres {fide Mrs. Talbot). Leaves 10-15 cm. long, 

 3'0-4'5 cm. broad; petiole 2-3 mm. long. Sepals + 7 mm. long. 

 Outer petals concave, + 23 mm. long ; inner petals 13-15 mm. long. 

 Carpels + 2 mm. long, style shorter than the ovary. 



This belongs to the series in which the inner petals are similar to 

 the outer, but smaller. 



Closely allied to U. hirstita Benth. from Fernando Po, but differs 

 in the narrower leaves and semiamplexicaul, broad, hairy bract 

 situated towards the base of the peduncle. 



[Bark dull gi"ey lichen-green. Two sepals bronze, four petals 

 white. Stamens numerous, anthers orange, filaments white. Small 

 buds dull pink, afterwards bronze. — P. A. T.J
