56 cxxiiic. MORACE.E (Rendle). [Dorstenia, 



58. D. Talbotii, Rendle in Joum.Bot. 1915, 301. Stem herbaceous; 

 younger portion densely covered with rather stiff whitish brown hairs, 

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

 acuminate, narrowing below to a blunt obscurely cordate base, margin 

 entire, about 4 in. long, and If in. wide, glabrous except for a few 

 small hairs on the prominent veins on the lower face ; lateral nerves 

 7-8 on each side, curving upwards and uniting in a marginal 

 nerve ; petiole 2-3J lin. long. Stipules linear-tapering, 2 lin. or less 

 in length, somewhat persistent. Inflorescence solitary in the upper 

 leaf-axils ; stalk slender, pubescent, much longer than the petioles, 

 1 in. long ; receptacle suborbicular, convex, about 4 lin, in diam,, 

 with a membranous margin barely 1 lin. wide, bearing about 10 

 radiating somewhat unequal linear bract-arms to J in. long, and 

 intervening triangular teeth or very short linear arms. Male flowers 

 3-androus ; perianth 3-lobed ; female flowers dispersed through the 

 more central portion of the disc ; style 2-lobed, projecting from the 

 tubular mouth of the perianth. 



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. 



59. D. Batesii, Rendle in Journ. Bot. 1915, 301. Stem erect, 

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

 long and IJ lin. in diam. below, becoming shorter upwards to J or 

 J in. Leaves obovately oblong-elliptic with a cuneate base, apex 

 shortly and abruptly acuminate, base obtuse, margin obscurely 

 crenate or slightly undulate, 3J-6J in. long, 1§-2J in. wide, glabrous 

 and dark green above, paler beneath and sparsely pubescent on and 

 near the nerves ; lateral nerves 10-12 on each side, ascending, then 

 upcurving and uniting below the margin, somewhat prominent 

 beneath ; petiole stout, 11-7 lin. long. Stipules minute, shortly 

 narrowly triangular, f lin. long. Inflorescences few, solitary in the 

 upper leaf-axils ; stalk stout, puberulous, about as long as the 

 petiole; receptacle flat, orbicular, disc | in. in diam., with a narrow 

 margin about J lin. wide, produced into numerous very unequal flat 

 linear bracts with a blunt or 2-lobulate apex, about 10 ranging from 

 f to IJ 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. Lujce, De Wild., but distinguished by the proportionately longer 

 narrower leaves with obtuse base, and the receptacle with many bracts exceeding 

 its diameter in length. 



60. D. yambuyaensis, De Wild. Etudes Fl. Bas- et Moyen-Congo, 

 ii. 241, and iii. 6Q,fgs. 2 and 3, t. v. Stem erect, 1-2 ft. high, her-
