tubo calycem longe excedente sub limbo le^^ssime amplificato 

 puberulo ore dense pubescente lobis obovatis obtusissimis ; ovario 

 oblongo glabro ; sfijlo incluso piloso. 



Oban ; n. 972. 



Leaves 2' 5-3 x l'7-2"2 cm., when dry olive-green above, grey 

 below, nerves conspicuous on the underside, the reticulum very open ; 

 petioles usually' 8-15 mm. long. Peduncles about 5 mm. long,

 in the dry state, bright green ; lobes 3 nnn. long. Tuhe of corolla 

 4' 5 cm. long, 1 mm. broad below, at the mouth scarceh- 2 mm.; 

 lobes 8x6 mm. Fertile anther-cell linear-oblong, 1'3 cm. long. 

 Ovary about 5 mm., style 3"5 cm. long. 



Recognised by the oblong calyx together with the very short leaves. 



The ovary of the flower examined having been partialh- destroyed 

 by insects, the description of that organ maj' have to be corrected. 

 There is a coloured drawing of this plant.

Oban ; nn. 385, 1527. 



Lamina of leaf vip to 16 x 7 cm., but usually less (youngest 

 leaves 5 x 3-4 cm.), faintly shining, on either side thicldy stre"mi 

 with cystoliths ; petioles 1-3 cm. long. Inflorescences (corollas not 

 included) 6-10 cm. long. Pedicels 2-3 mm. long. Bract mostly 

 1-2 cm., hracteoles only 2 mm. long. Flowers blue-mauve. Calyx 

 2 • 5 cm. long, the segments 1-1 • 5 mm. wide, posticous ones united only 

 for 1 mm. Corolla 4' 5 cm. long; tube 3-4 nmi. wide below, and 

 8-11 mm. above ; lobes about 12 mm. long. Filaments puberulous, 

 5-7 mm. long. Anthers 4x1 mm. Capsule + 2 cm. long, brown, 

 faintly shining. Seeds suborbicular, dark, 1"5 mm. in diameter. 



A very distinct species, known at once by its narrow bracts and 

 calyx-segments. D. togocnsis Lindau has the segments of its cah'x 

 still narrower, but is in man}- other respects quite different. 



A North Cameroons specimen (imperfect) in the British IMuseum 

 {Conran, sine no.), communicated from Berlin under the name of 

 Disehistoealyx Buchholzli Lindau, appears to come very close to 

 this. The Cameroons plant does not agree with the description of
