This plant is hardly distinguishable in the dried state from D. Hildebrandtii, but 
has yellow flowers. The bracteoles are ¢ in. long, linear; not 3} in., elliptic, as 
stated by Lindau (of the floral leaves probably). 
18. D. Volkensii, C. 2. Clarke. Sparingly pubescent. Leaves up 
to 1? by 1 in., elliptic, obscurely crenulate ; cystoliths not prominent ; 
petioles 0-} in. long. Cymes axillary, 3-10-flowered. Calyx rather 
more than } in. long, divided } the way down ; tube scabrous pubescent 
Without, white hairy within. Corolla 1-1} in. long, not 2-lipped ; 
lobes 5, subequal, obtuse. Stamens 4; anthers subequal, tailed at the 
base ; pollen longitudinally ribbed. Capsule } in. long, linear-cylindric, 
4-seeded. Ovary 4-ovuled.—Hygrophila Volkensii, Lindau in Engl.

__ _ This plant is hardly distinguishable from D, Hildebrandtii. Lindau distinguishes 
it by having the capsule hairy ; the young capsules are perfectly glabrous, Lindan 
8 10 error in saying that the calyx is divided 3 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 1 in. long; bracteoles 4, in. long, linear, 
a little distant, Calyx up to 3-3 in. long, divided half-way down 
or More, densely covered with long several-celled gland-tipped hairs.
