364 SAXIFRAGACE E. Visite 
are only 5, and opposite to the petals) ; or (in Bauera) indefinite : fila- 
ments subulate : anthers ovate, 2-celled, bursting longitudinally or (in 
Bauera) by two pores. Ovarium partly coherent with the tube of the 
calyx, formed of two (rarely 3-5) carpels, cohering by their introflexed 
sides or margins: styles as many as the carpels, distinct, or more or 
less combined: stigmas capitate or clavate. Placente along the intro- 
flexed margins of the carpels, either throughout the whole length, or 
at the base only, or at the apex, usually separating with the carpels, 
rarely attached to a central axis. Fruit capsular, usually of two (rare- 
ly 3-5) earpels or valves, the margins of which are either entirely in- 
troflexed, or partly introflexed, or scarcely at all and the fruit is then 
1-celled : carpels dehiscing at the ventral suture, separating from each 
other, either from the base upwards, or from the apex downwards. 
Seeds usually numerous, rarely definite: albumen fleshy. Embryo 
small, in the midst of the albumen: radicle pointing towards the hilum.

Calyx-tube cohering with the ovary : limb 5-partite, persistent : eestivation 
valvular. Petals 5, entire, spreading, shorter than the calyx. Stamens 5. 
Anthers versatile. Styles 2. Stigmas capitate. Capsule 1-celled, 2-valved, 
truncated at the apex, 5-furrowed, crowned with the limb of the calyx, 
many-seeded. Placents free, pendulous from the apex of the cell. Seeds 
convex on the outer side, concave on the inner, or minute oblong and some- 
what angular or compressed.—Herbaceous, pubescent or slightly villous, 
dichotomously branched plants, natives of Africa and India. Leaves oppo- 
site; exstipulate, entire and quite entire, acute. Flowers yellow or white, 
axillary, shortly pedicelled, usually in pairs, with or without a common 
peduncle. 
In Dr Wallich’s List this genus is still referred to Onagrarie.
