 I)lacentas inserted on the middle of the septum. C'apmle small, subglobose, sep-

Whole plant 4-1 in. high, simple or branched from the base, pubescent. Leave& 

 2-4 in., elliptic-oblong or -lanceolate, obtuse or obtusely acuminate; petiole long or 

 short, often winged ; nerves many, very spreading, often red-brown when dry i stipules- 

 filiform. 



25. OFKXORRKXZiV, Z. 



Erect creeping or decumbent small herbs, rarely undershrubs. Leave? usually 

 elliptic-lanceolate ; stipules caducous. Floioeis white pink or greenish, secund 

 on the branches of axillary or terminal dichotomous cymes ; bracts or bracteoles 

 various or 0. Calyx-tube short ; lobes 5, small, persistent. Corolla tubular or- 

 funnel-shaped ; lobes 5, short, valvate in bud, back often winged, often also with 

 a fold in the sinus. Stamens 5, inserted on the tube ; anthers linear. Dish very 

 large, 2-lobed. Ovai-y 2-celled ; style filiform, stigmas broad or linear ; ovules 

 many, inserted on basal ascending placentas. Capsules coriaceous, compressed, 

 obcordate, girt in the middle by the calyx-tube, the crown dehiscing by 2 broad 

 gaping valves ; placentas divaricating, many-seeded. Seeds minute, angled, testa 

 crustaceous ; embryo clavate, in fleshy albumen. — Distkib. Species about 50, 

 tropical Asiatic, with a few Australian and Polynesian. 



A very difficult genus ; the characters taken from the position of the stamens on 

 the corollar-tube, the hairiness within of the latter, the length and smoothness or 

 hairiness of the style, and the form of the stigma, have not been made diagnostic, as 

 being probably sexual to a very great degree. 



* Bracteoles 0, or if present very narrow amd caducous, failing away before the 

 capsules are fuUy formed. Corolla y,sually undei- ^ in. long (except in O. Wal- 

 lichii). The species of this group are very closely allied indeed and difficult of 

 d^mition. 



1. O. niun^os, Linn.; erect, glabrous, or stem petioles cymes and leaf 

 nerves beneath pubenUous, stipules small, cyme-branches subumbellate very 

 spreading, bracts 0, calyx-teeth very short, corolla glabrous roimded at the tip 

 in bud ^ in., mouth not dilated, lobes very short obtuse keeled at the back.

A suf&utescent herb. Leaves 2-S by 1-2J in., very thin, elliptic or elliptic-lanceo-
