 nnder Pruuns. To tho species described on pp. 295-7, 

 Vol. !., the following should now bo added:

 nioro or iesa wtwKj-eiliated. O-^y one species calk for 



Ceratostigfma— continued, 



mention here. It thrives in ordinary garden soil, and 

 may be increased by divisions. 



C. plumbaginoldes (Plumhagodike). This is the correct name 

 01 the plant described on p. 169, Vol, III., as Pbttnbafjo Larpeiitce 

 (F.d. S. 307). SvN. Valoradia plumbaDinoldes {H. M. 4487). 



CEBATOTHECA (from keras^ kevfitos, a horn, and 



tluke, a case, a capsule ; in allusion to the horned fruit). 



Syn. Sporledera. Ord. Peddtinece. A small genus (two 



species) of erect, pubescent, stove or greenhouse, (? always) 



annual herbs, natives of tropical and South Africa. Flowers 



solitary in the axils, shortly pedicellate ; calyx five-parted 



or deeply five-cleft; corolla tube enlarged above, the limb 



&ub-bilabiate, with spreading lobes; stamens four, didy- 



namouB. Leaves opposite, or the upper ones alternate, 



ovate, toothed. C. triloha, the only species in eultiva- 



tion, is probably a biei nial. Seeds should be raised in 



heat, and the plants, when strong encugb, removed to tl e 



greenhouse. Rich loam, a sunny position, and plenty oi 



water when growing, are essentials to success. 



C. triloba (three-lobed). fi. in opposite pairs, shortly pedicellate, 

 with a minute, imperfect flower at the base of each ; calyx erect ; 

 corolla pale violet-purple, with darker streaks, Zin. long, pilose.

 varying from broadly ovate-cordate to broadly triangular and 

 threedobed, creuate, the broadest leaves 8iu. across ; floral ones 

 narrowly ovate, shorter than the flowers. Stem 5ft. high. Natal, 

 1886. (B. M. 6974.) 



CEREUS. About 200 species of this genus are known, 

 natives of tropical and sub-tropical America, the West 

 Indies, and tho Galapa<?os Islands. (See also Pilocereus.)
