1. D. Burmanni, Vdhl ; DC. Prod. i. 318. Leaves all radical, 

 rosulate, cuneate-spathulate, lamina equalling- or exceeding the broad 

 petiole. Stipules connate intra- axillary scarious fimbriate, half as long 

 as petiole. Scape and pedicels glabrous ; pedicels secund, about equal- 

 ling the papillose fruiting calyx. Styles 5, undivided, slender; stigmas 

 radiate-papillose. Placentas 5. 



Upper Guinea. Sierra Leone, Afzelius. 

 Description from M. Planchon's memoir. 

 Also in Tropical Asia and Australia. 



2. D. Burkeana, Planch, in Ann. Sc. Nat. ser. 3, ix. 192 Acaulescent. 

 Leaves more or less compactly rosulate, obovate or rotundate-cuneate, 

 upper surface especially towards the margin clothed with stipitate 

 glands ; lamina \-\ in. broad, petiole pubescent or glabrate, \-\ in. 

 Stipules membranous, intrapetiolar, cut into about 3-5 or more teeth. 

 Scape erect with the inflorescence glandular-puberulous, 2-3 in. to 1 ft., 

 few- to many-flowered. Pedicels nearly equalling the cnlyx. Flowers 

 purple. Styles 3, each bipartite, branches slender, simple or bidentate 

 at apex. 



Lower Guinea. Huilla, Angola, Dr. Welwitsch! 

 Also south of the Tropic. 



3. D. affinis, Welw. sp. nov. Acaulescent. Leaves tufted, erect, on 

 long slender glabrous petioles, lamina linear- spathulate,. obtuse, gra- 

 dually narrowed from near the apex downwards, clothed with spread- 

 ing stipitate glands to the petiole, together with it 2-3| in. long, 

 lamina 1-2 lines broad above. Stipules more or less laciniate. Scape 

 erect, glabrous, 2-3 times longer than leaves. Pedicels shorter than 

 the puberulous ciliolate lobed calyx ; bracts 1 line more or less, linear. 

 Petals blue-purple. Styles 3, each divided to the base into two 

 slender branches equalling or exceeding the ovary. 



Lower Guinea. Huilla, Angola, Dr. Welwitsch! 



Near to D. capensis, in which, however, the leaf-lamina is uniformly linear or even 

 slightly narrowed towards the apex. 



4. D. indica, Linn. ; DC. Prod. i. 319. Stems elongate, ascending, 

 leafy. Leaves narrow-linear, attenuate above, upper surface clothed
