ascending somewhat curved densely hispid stems to 20 in. long, 
with internodes up to ? in. long. Leaves membranous, glabrous, 
elliptic, apex subobtuse, narrowing cuneately below the middle 
to a subobtuse base, with 2-3 coarse blunt teeth near the apex,

less in length. Inflorescences 2-4, axillary ; stalk hispid, 23 lin. 
long ; receptacle green, subturbinate, about 3 lin. high, face broadly 
oval, 3 lin. long, 24 lin. broad, with two linear bracts 5 lin. long 
and 4 lin. broad dilating at the end to 1 lin., and several lateral 
deltoid blunt bracts } lin. long. Male flowers numerous, brownish ;

21. D. gabunensis, Engl. Monogr. Morac. Afr.14. Stem woody 
below, glabrous, herbaceous above and like the petioles densely 
clothed with uncinate hairs ; upper internodes about 4 in. long and 
13-2 lin. thick. Leaves thinly membranous, oblong-lanceolate,

4-5 in. long, 14 in. wide in the upper third; bright green above, paler 
beneath ; lateral nerves about 7-9 on each side, curving upwards ;

linear-lanceolate arms on each side about } in. long, with inter-

The above description is drawn up from Engler’s original one. There is in 
Kew Herbarium a sheet of Soyaux, 26, the label of which gives the localit and 
date cited by Engler, but the two specimens on the sheet represént different 
Species. One specimen may be referable to D. gabunensis, but has shorter 
stipules (about 14 lin. long), larger petioles, and broader blades with a shorter 
broader apex ; with this Bates’s plant from the Cameroons agrees. 
22. D. Tessmannii, Engl. in Engl. Jahrb. xlvi. 274. Stem herba- 
ceous and like the petioles densely clothed with short hairs, about 
1 ft. high ; internodes about 5 lin. long. Leaves oblong-lanceolate,
