as also are the petioles. Leaves elliptic to obovate-elliptic, shortly

entire, about 4 in. long, and 1} in. wide, glabrous except for a few 
small hairs on the prominent veins on the lower face; lateral nerves

Upper Guinea. Southern Nigeria: Oban, Talbot, 2314! 
Belongs to the D, Barteri group, in which it is distinguished by its narrow- 
margined receptacle with numerous rather short subequal arms.

herbaceous, shortly hirsute, as are the petioles; internodes 1}. in.

upcurving and uniting below the margin, somewhat prominent 
beneath ; petiole stout, 11-7 lin. long. Stipules minute, shortly 
narrowly triangular, ? lin. long. Inflorescences few, solitary in the 
upper leaf-axils; stalk stout, puberulous, about as long as the 
petiole ; receptacle flat, orbicular, disc 3 in. in diam., with a narrow 
margin about 4 lin. wide, produced into numerous very unequal flat 
linear bracts with a blunt or 2-lobulate apex, about 10 ranging from 
2 to 14 in. long, the intermediate shorter ones sometimes reduced to 
mere teeth. Male flowers 3-androus; perianth 3-lobed; female 
distributed through the disc, with 2-fid projecting style. 
Upper Guinea. Cameroons: Efulen, Bates, 386 ! 
Near D. Luje, De Wild., but distinguished by the proportionately longer 
narrower leaves with obtuse base, andthe receptacle with many bracts exceeding 
its diameter in length.
