198 THE WATERI.ILIES. 



sinuate-dentate ; thin and membranaceous ; younger ones glabrous, adult or sub-adult 

 leaves glabrous above, densely pilose beneath with very short hairs; veins slightly 

 prominent above, manifestly so beneath; venation loose, conspicuous; flowers 5 to 7 

 cm. in diameter, ' white ' ; sepals 4, ovate-lanceolate, acute, whitish within, light green 

 outside ; petals 7 to 8, smaller than the sepals, and becoming decidedly smaller and 

 narrower inward; stamens 35 to 45, broadly linear; anthers rather short, connective 

 scarcely produced ; carpels several. 



" Leaf 10 to 15 cm. long, 9 to 13 cm. wide; the sinus is about 2 to 4 cm. wide 

 at base of lobes. The sepals are 2.5 to 3 cm. long, 7 to 10 mm. wide ; the petals decrease 

 in size inward down to 2 cm. long and 4 mm. wide. The outermost stamens are about 

 2 cm. long and 3 mm. wide at base, anthers 7 mm. long by 2 mm. wide." (E. Gilg.)

GEOGRAPHIC DISTRIBUTION. " Cameroon : Bipindi, in slowly flowing brooks and 

 in streams of the Lokundje at Bequanohe. Coll. Zenker, No. 2130. Flower in July." 

 (E. Gilg.) 



NOTES. Finding this species labeled by Professor Gilg in several European her- 

 baria, but there being as yet no published description, we were favored by the Berlin 

 professor with the above description from his own pen, based on the specimens in 

 the Royal Herbarium. We have gladly inserted it therefore, translated verbatim 

 from the Latin and German in which it was communicated.

Flowers small, white; stamens yellow. Leaves small, ovate, dark green. Fruits 

 numerous, nearly spherical, contracted above, dark green. Seed spherical-ovoid,
