they are crenate and shorter than the petiole ; in his the 

 calyx is said to be persistent with the lobes acute, while in 

 this it is deciduous with the lobes obtuse. They must, 

 nevertheless, be very nearly allied to each other.

D. tomentosa, acaulis, foliis radicalibus petiolatis ovato- 

 ellipticis, basi obtusis vel subcordatis, apice obtusissimis, cre-

 scapis folio longioribus trichotomis, bracteis oblongis, obtusis, 

 tomentosis, lobis calycinis villosis, linearibus, obtusis, per- 

 sistentibus, caps, pollicaribus siliquosis apice attenuatis. 



Hab. — On moist shady rocks above Rambodde ; at an 

 elevation of from 4000-5000 feet above the sea. Fl. nearly 

 all the year. 



Descr. — Herbaceous, stemless, tomentose. Leaves with long peti- 

 oles, ovate elliptical, obtuse or slightly cordate at the base, with a 

 very obtuse apex, crenate, pennivenous, veins about 5 on each side, 

 pilose- tomentose above, densely lamiginosely tomentose beneath, par- 

 ticularly on the veins, exclusive of the petiole from 3-3£ inches long, 

 by from 2-2^ broad. Petioles flattened, a little winged above from 

 the decurrent base of the lamina, tomentose, from 2-3 inches long. 

 Scapes numerous, pilose- tomentose, longer than the leaves, about 

 three times trichotomously divided, the lower divisions subtended 

 by two oblong obtuse tomentose bracts about 3 lines long, those of 

 the upper ones smaller. Pedicels slender, pubescent, from 6-8 lines 

 long. Calyx free, persistent, villous, deeply 5 -parted, lobes linear, 

 obtuse, of a dark brown colour, about 3 lines long. Corolla about 

 an inch long, and nearly as much broad, of a white colour with a 

 slight tinge of purple, hypogynous, gamo-petalous, tubular at the 

 base, ventricosely campanulate above. Limb 5-cleft, bilabiate, upper 

 lip 2-lobed, lobes ovate, obtuse, reflexed, lower lip 3-lobed, lobes 

 broadly ovate, obtuse, about equal spreading. Stamens 4, the poste- 

 rior pair abortive, the anterior pair fertile, the filaments of which are 

 very much thicker than the others, and sigmoidly curved. Anthers
