tuberous, succulent, watery, edible, delightfully refreshing ; stem 

 lactescent, scarcely branched or furnished with abbreviated leafy 

 branchlets, fleshy, cylindrical, somewhat reddish ; leaves lactescent, 

 elliptic-lanceolate, somewhat fleshy, veined, the veins impressed on 

 the upper face, raised on the lower ; [flowers clustered on the hemi- 

 spherical receptacle. In sandy thickets among low herbs near Lopollo, 

 sparingly and sporadic ; fl. and few fr. 25 Dec. 1859. No. 1566. 



In some respects allied to D. indica Wall. List, n. 4639 (1831), but 

 the leaves are subsessile, and it can be easily distinguished by the 

 tuberous root. D. indica is reported to have been collected by Mr. 

 Last at the Usagara district of Central Africa : see Mitten in Journ. 

 Linn. Soc. xxii. p. 299 (1886) ; but this distribution of the species is 

 not recognised in Hook. f. Fl. Brit. Ind. v. p. 494 (1888).

 n. 68 (1859), as a new genus allied to Morus. The moss n. 132, 

 ScMotheiriiia rugifolia Brid. grew on the trunk of "Mucamba-Camba " 

 at Sange in Dec. 1854.
