158 HEXANDRIA MONOGYNIA. DvaCCBna, 



A slender, leaning, shrubby species, from three to 

 four feet in height, a native of Sumatra, from thence in- 

 troduced, by the late Dr. C Campbell into the Botanic 

 Garden at Calcutta, where it flowers during the hot 

 months of March and April. The variegation of the co- 

 lour of the leaves makes it interesting and ornamental. 



Stems tending to be erect, but from their weak texture, 

 leaning much to one side. Branches few, and like the 

 stems ; general height of five year old plants, from three 

 to four feet. Leaves alternate, approximate, sheathing, 

 from lanceolar to oblong, entire, smooth, strongly mark- 

 ed with circular spots of a deeper, or lighter yellow ; 

 from four to eight inches long, and from one to three 

 broad. Panicles (in stunted plants racemes) terminal ; 

 thin, smooth, variously bent. Flowers scattered, pedi- 

 celled, pretty large, pale greenish yellow. Bractes soli- 

 tary, ensiform, one, rarely two-flowered. Corol ; tube 

 gibbous ; border six-parted ; segments linear, length of 

 the tube. Filaments six, inserted on the base of the seg- 

 ments of the border of the corol and of their length. An- 

 thers incumbent. Germ superior, obovate, three-celled, 

 with one ovula in each, attached to the axis below its 

 middle. Style length of the corol. Stigma composed of 

 three, roundish, beautiful granulated lobes.
