Dene, in DC. Prodr. viii. 648. B. lasiantha, Wight Ic. t. 1286. Caralluma 

 crenulata, Wall. PL As. Ear. i. 6, t. 7. 



DECCAN PENINSULA ; Nuggur hills, near Madras, Wight. DISTRIB. Ava. 

 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. 



TRAVANCORE ; arid rocks, alt. 2000 ft., Wight. 



"The very diffuse habit, a single plant corering 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 I.e. 



4. B. Hitchinia, Dene, in DC. Prodr. viii. 649; stem slender diffusely 

 branched, flowers few in an umbel, corolla hairy within. Hitchinia indica,

The CARNATIC and CIRCARS, Wight, &c. 



Branches ^ in. diam. Flowers shortly pedicelled. Corolla f in. diam. Coronal 

 lobes 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. 



SOUTH 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I have an unpublished lithograph of this plant made for Dr.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. Fl.

Dry hills in the WESTERN PUNJAB; the Saltrange, &c. DISTRIB. Affghanistan, 

 Beloochistan, Persia, Arabia. 



Plant 2-6 in. high ; branches ^-\ in. diam. Sepals ovate-lanceolate. Corolla 

 ^ in. diam., dark purple, more deeply divided into narrower lobes than in any of the 

 southern species. Follicles 3-4 in., tips capitate. 



ORDER XCVI. LOOANIACEJE. (By C. B. Clarke.)
