Apparently similar in habit to B. umbellata, differing chiefly in the hairy inner 
-surface of the corolla. 
3. B. diffusa, Wight Ic. t. 1599; diffuse, branches very stout, flowers in 
dense umbels, corolla-lobes fimbriate on the margin only.

* The very diffuse habit, a single plant covering many square feet of surface, the 
minute cauline teeth, small sepals, and distinctly tubular corolla of this plant, com- 
bine to mark the species as very distinct from any of its Indian congeners," Wight Lc. 
4. B. Hitchinia, Dene. in DC. Prodr. viii. 649; stem slender diffusely 
branched, flowers few in an umbel, corolla hairy within. Hitchinia indica,

Branches 4 in. diam. Flowers shortly pedicelled. Corolla 3 in. diam. Coronal 
Jobes shorter than in B. umbellata, inner process larger in proportion and decurrent. 
5. B. pauciflora, Wight mss.; Dene. in DC. Prodr. viii. 648 ; stems 
slender diffusely branched, teeth or angles recurved, flowers solitary, corolla 
hairy within. 
Soutu Carnatic; at Palamcottah, Wight. 
I have an unpublished lithograph of this plant made for Dr. Wight, and there are 
specimens in his Herbarium, but not sufficient for full analysis; the stems are as 
slender as in B. Hitchinia, the corolla campanulate, 1} in. diam. with broad short 
acute lobes banded closely with purple, and the inflexed process from the corona is 
short and very broad, 
6. B. Aucheriana, Dene. in DC. Prodr. viii. 649 ; stem short branched, 
flowers capitate, corolla-lobes lanceolate glabrous pustular above. Boiss. FI
