34 cxxiiic. MORACE^ (Rendle). [Dorstenia. 



9. D. ophiocomoides, Engl, in Engl. Jahrh. xl. 545. Suffruticose ; 

 stem from a long creeping rooting portion, densely hirtellous as are 

 the petioles. Leaves short-stalked, narrowly elliptic to oblanceolate- 

 elliptic, apex acuminate, tapering below to a narrow obscurely 

 cordate base, margin undulate, 3-4 in. long, a little over 1 in. wide, 

 glabrous except for a few sparse short hairs on the veins on the 

 paler lower face ; lateral nerves 6-7 on each side, ascending, uniting 

 a little within the margin ; petioles 2-3 lin. long. Stipules as in D. 

 ophiocoma. Inflorescence solitary; stalk slender, f in. long (or more), 

 sparsely hirtellous as are the outside of the receptacle and the 

 bract-arms. Receptacle similar to that of D. ophiocoma but smaller 

 (4 lin. in diam.), with a few (4) longer, bract-arms |-1 in. long, and 

 about the same number of shorter intermediate. Male flowers 3- 

 androus. 



Upper Guinea. Cameroons : Lundi, near Bipinde, 500 ft., Zenker, 2709 ! 



Very near D. ophiocoma but distinguished by its smaller narrower leaves and 

 smaller receptacle with unequal bract -arms. 



10. D. laikipiensis, Rendle in Journ. Bot. 1915, 299. A small 

 herb becoming woody below ; stem and petioles densely hirtellous. 

 Leaves shortly stalked, obovate, apex blunt to rounded, base blunt to 

 obscurely cordate, margin obscurely undulate, 3-3Jin. long, lj-l|in. 

 wide, upper face glabrous, lower sparsely hairy mainly on the nerves ; 

 lateral nerves about 5 on each side, curving upwards and uniting 

 within the margin ; petiole j-J in. long. Stipules as in D. mungensis, 

 persistent. Inflorescence solitary, receptacle broadly convex, hirtel- 

 lous, surface orbicular about 4 lin. in diam., the margin prolonged 

 into about 15 very unequal bract-arms, varying from triangular 

 projections 1 lin. in length, to slender arms nearly f in. long, Endo- 

 carp crustaceous, warted, about 1 lin. in diam.

11. D. mungensis, Engl, in Engl. Jahrh. xx. 145. Suffruticose; 

 stem 6-8 in. high, ascending, rooting below, roots fibrous, stem and 

 petioles densely hirtellous. Leaves shortly stalked, elliptic to 

 obovately elliptic, tapering to a shortly acuminate apex and an obtuse 

 obscurely cordate base, margin undulate or sometimes with a 

 few large irregular teeth in the upper part, li-3J in. long, j-lj in. 

 wide, glabrous, under surface paler ; lateral nerves 5-7 on each side, 

 curving upwards and uniting within the margin ; petiole about J in. 

 long. Stipules triangular-subulate, 1-2 lin. long, persisting as long 

 as the leaf. Inflorescence solitary ; stalk slender, generally about 

 1 in. long, sometimes more, puberulous ; receptacle almost hemi- 

 spherical, surface suborbicular, 3-7 lin. across, dark purple or greenish, 

 with a very narrow margin and generally 4-7 narrow linear glabrous 

 bracts J-1 in. long (or more) and intermediate irregularly arranged
