26 LXXV. RUBIACEJ;. (J. D. Hooker.) \_Stepliegyne. 



10-12 pair; petiole j-1 in.; stipules large, obovate, membranous. Peduncles ter- 

 minal, usually 3-nate with the middle ones very short or 0, the lateral 1-3 in. ; 

 bracted leaves petioled ; bracts very caducous. Heads 1 j in. cliam. ; flowers glabrous ; 

 stigmas cylindric, truncate at both ends. Capsules \ in. including the calyx, ribbed, 

 nearly glabrous. 



3. S. diversifolia, Hook.f. ; leaves orbicular-cordate oblong or elliptic, 

 tip rounded, calyx-limb 0, corolla-tube equalling the bearded lobes. N. diver- 

 sifolia, Wall. Cat. 6096; G. Don Gen. Syst. Hi. 467. N. parvifolia, var. 2,

CHITTAGONG, Roxburgh, &c. TENASSERIM and BIRMA, Wallich, &c. DISTRIB. 

 Philippines. 



A small tree. Leaves deciduous, glabrous or pubescent beneath; the lower 

 orbicular-cordate, 10 in. diam., coriaceous, the upper 4-6 by 2-3 in. and mem- 

 branous, nerves oblique ; petiole f-l in. ; stipules obovate-oblong. Heads white, in 

 spreading 3-chotomous panicles, nearly 1 in. diam.; foliar bracts long-petioled ; 

 corolla glabrous except the lobes within ; stigma elongate, mitriform. Capsules ^in. 

 long, smooth, ribbed. I have preferred Wallich's and Don's name of diversifolia to 

 Roxburgh's of rotundifolia, as expressing the very remarkable difference between 

 what I take to be the upper and lower leaves of the branches.
