This plant is hardly distinguishable in the dried state from D. Hildehrandtii, but 

 has yellow flowers. The bracteoles are ^ in. long, linear ; not ^ in., elliptic, as 

 stated by Lindau (of the floral leaves probably). 



18. D. Volkensii, C. B. Clarke. Sparingly pubescent. Leaves up 

 to If by 1 in., elliptic, obscurely crenulate ; cystoliths not prominent ; 

 petioles 0-J in. long. Cymes axillary, 3-10-flowered. Calyx rather 

 more than J in. long, divided J the way down ; tube scabrous pubescent 

 without, white hairy within. Corolla 1-1 J in. long, not 2-lipped ; 

 lobes 5, subequal, obtuse. Stamens 4 ; anthers subequal, tailed at the 

 base ; pollen longitudinally ribbed. Capsule J in. long, linear-cylindric, 

 4-seeded. Ovary 4-ovuled. — Ilygrophila Volkensii, Lindau in Engl.

This plant is hardly distinguishable from D. Hildehrandtii. Lindau distinguishes 

 it by having the capsule hairy ; the young capsules are perfectly glabrous. Lindau 

 is in error in saying that the calyx is divided \ the way down. 



19. D. mollis, C. B. Clarke. Hairy; branches with many long 

 several-celled gland-tipped hairs. Leaves hairy on both faces. Cymes 

 rather lax, pedicels often \ in. long ; bracteoles -^ in. long, linear, 

 a little distant. Calyx up to §-f in. long, divided half-way down 

 or more, densely covered with long several-celled gland-tipped hairs. 

 Capsule exceeding |- in. in length ; otherwise as D. Hildehrandtii.

20. D. tanganyikensis, C. B. Clarke. Ashy-puberulous ; branches 

 numerous, hardly 4 in. long, from a very stout rootstock (apparently 

 after be'ng burnt down). Leaves J-f by \ in., elliptic, obtuse, narro«\-ed 

 at the base, scarcely petioled. Flowers in numerous few-flowered axillary 

 dense cymes. Calyx J in. long, divided more than \ way down. Corolla
