20. D. lotziana, Engl, in Engl. Jahrh. li. 431. A herb with 

 ascending somewhat curved densely hispid stems to 20 in. long, 

 with internodes up to J 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, 

 2-3 J in. long, 1-1 1 in. wide ; lateral nerves 3 on each side, curving 

 upwards, with the remotely reticulate veins subprominent beneath ; 

 petiole hispid, 2J lin. or less in length. Stipules subulate, 1 lin. or 

 less in length. Inflorescences 2-4, axillary ; stalk hispid, 2J lin. 

 long ; receptacle green, subturbinate, about 3 lin. high, face broadly 

 oval, 3 lin. long, 2J lin. broad, with two linear bracts 5 lin. long 

 and I lin. broad dilating at the end to 1 lin., and several lateral 

 deltoid blunt bracts J lin. long. Male flowers numerous, brownish ; 

 female distributed throughout the disc ; style 2- fid . Fruits subglobose, 

 1 lin. in diam. ; endocarp smooth.

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 J in. long and 

 lJ-2 lin. thick. Leaves thinly membranous, oblong-lanceolate, 

 apex abruptly acuminate, narrowing below to a cuneate base, 

 4-5 in. long, I'j in. wide in the upper third ; bright green above, paler 

 beneath ; lateral nerves about 7-9 on each side, curving upwards ; 

 petiole broadly channelled, about I in. long. Stipules triangular- 

 acute, about \ in. long, persistent. Inflorescence solitary in the 

 upper leaf-axi£, very shortly hairy ; stalk a little longer than the 

 petiole ; receptacle face subrhomboid, dark purple, about 7 lin. 

 long, 4 lin. broad, with a narrow margin, bearing a long linear apical 

 bract-arm 1 in. long, a linear obtuse basal arm, and about 7 

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

The above description is drawn up from Knglers original one. There is in 

 Kew Herbarium a sheet of Soyaux, 2(3, the label of which gives the locality and 

 date cited by Engler, but the two specimens on the sheet represent different 

 species. One specimen may be referable to D. yabuucnsis, but has shorter 

 stipules (about 1^ lin. long), larger petioles, and broader blades with a shorter 

 broader apex ; w^ith this Bates's plant from the Cameroons agrees. 



22. D. Tessmannii, Engl, in Engl. Jahrh. xlvi. 274. Stem herba- 

 ceous and like the petioles densely clothed with short hairs, about 

 1 ft. high ; internodes about 5 lin. long. Leaves obloug-lauceolaie,
