135. Ophiorrhiza L.' — Flowers hermaphrodite or polygamous ; 

 receptacle subglobose {Vohjura '), turbinate or compressed-cymbifoim, 

 sometimes obconical (Palenhamia^), Calyx short; teeth 5, rather 

 remote, acute or obtuse (Polyiira), persistent around fruit. Corolla 

 tubular funnel-shaped ; lobes sometimes winged at back, valvate. 

 Stamens, disk &c. of Ohknlandia. Germen adnate to receptacle, 

 sometimes free at apex, 2- celled ; branches of slender style 2 stigma- 

 tose obtuse or oblong, sometimes capitellate. Ovules in cells oc, 

 inserted on a subglobose or obovoid ascending placenta affixed to 

 bottom of septum. Fruit capsular subglobose (Pohjitra), obconical 

 (Pakenhaniia), or oftener much compressed contrary to septum, mitre- 

 shaped, widely 2-lobed or 2-winged, sometimes obcordate, truncate 

 above or sub-2-dymous, dehiscing septicidally {Pohjuva) or loculicidally 

 above; cells sometimes finally solute. Seeds go, minute angular, 

 smooth, granular or papillose, richly albuminous ; embryo clavate, 

 2-fid or 2-lobed. — Erect or drooping herbs, sometimes subshrubby ; 

 leaves opposite ^ petiolate membranous, sometimes unequal ; stipules 

 interpetiolar, solitary or 2-nate ; flowers ^ in 2-chotomous or some- 

 times 1 -parous recurved cymes ; bracts small or subfohaceous. {Trop. 

 and siihtrop. Asia and Oceania.^)
