2. D. elliptica, Bureau in DC. Prodr. xvii. 271. Stem slender, 

 woody in the lower portion from which the leaves have fallen, 

 herbaceous and leafy above, youngest portion shortly and densely 

 pilose, otherwise glabrous. Leaves papery when dry, elliptic, 

 apex shortly acuminate, tapering to the base and passing into the 

 short petiole, margin entire or subrepand, 7J-8 in. long, 2J in. wide, 

 smooth and bright green above, paler beneath ; lateral nerves as in 

 D. frutescens ; petiole 2J-5 lin. long. Stipules as in D. frutescens. 

 Inflorescence solitary in the upper leaf -axils ; stalk J in. long ; 

 receptacle closely resembling that of D . frutescens and bearing a few 

 small scattered bracts on the unequally ribbed convex surface. —

Engler does not appear to have seen this plant and bases his description on 

 the original one of Bureau, who has overlooked the small bracts on the convex 

 surface of the receptacle, and has thus led Engler to place the species in his sec- 

 tion Eudorstenia, while D. frutescens constitutes his section Nothodorstenia. The 

 two species might perhaps be regarded as conspecific ; there is, however, a 

 difference in the general shape of the leaves, those of D. elliptica being narrower 

 with much less tendency to broaden above the middle than in D. frutescens. 



3. D. ciliata, Engl, in Schlechter, Westafr. Kautsch.-Exped. 286 

 {name only) and in Engl. Jahrh. xxxiii. 114. A herb 20 in. high ; stem 

 and petioles pubescent, the former reaching 2 lin. in diam. in the 

 lower part. Leaves membranous when dry, oblong- elliptic to broadly 

 elliptic, apex shortly acuminate, more or less tapering to the narrow 

 rounded base, margin entire or obscurely crenate, 3J-9 in. long, l-|-4 

 in. wide, glabrous and dark green above, pale beneath and minutely 

 punctulate and sparsely pubescent on the nerves ; lateral nerves 

 8-10 on each side, ascending, then curving upwards and uniting 

 within the margin, prominent beneath as also the connecting cross 

 unions ; petiole J-1 in. long (rarely more). Stipules inconspicuous, 

 1-1 J lin. long. Inflorescence in the upper leaf-axils ; stalk puberulous, 

 generally exceeding the petiole, IJ in. or less in length ; receptacle 

 suborbicular, 6-8 lin. in diam., brown, the margin bearing numerous 

 closely arranged very unequal linear puberulous green bract-arms 

 clavate and spathulately dilated above and varying in length from 

 1-6 lin. Male flowers 3-androus ; perianth with 3 broad lobes ; 

 female numerous, distributed ; style projecting and carrying the two 

 recurved branches above the tubular perianth. — D. hartnsiana, Engl,
