10 mm. long. Fruit with pedicel 2:0-2:5 cm. long, oblong, 
576 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.

staminibus numerosis connectivo ultra thecas dilatato; carpidiis

Tree 20-25 metres (fide Mrs. Talbot). Leaves 10-15 cm. long, 
9:0-4:5 em. broad; petiole 2-8 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. hirsuta Benth. from Fernando Po, but differs 
in the narrower leaves and semiamplexieaul, broad, hairy bract 
situated towards the base of the peduncle. 
[Bark dull grey lichen-green. Two sepals bronze, four petals 
white. Stamens numerous, anthers orange, filaments white. Small 
buds dull pink, afterwards bronze.—P. A. T
