pedicels, rarely exceeding the length of the leaves. Sepals broad ly-lanceolate, 

 keeled, with scarions mar*^ins, nearly 3 lines long. Petals longer, rather nar- 

 iw. Stamens usually 10, the 5 outer filaments dilated, especially below the 

 middle. Styles filiform. Capsule rather shorter than the calyx, the valves 

 leaviug much of the dissepiments attached to the central column. Seeds ob-

 ietals as many, hypogynous, imbricate and usually contorted iu the bud. 

 Stamens indefinite, hypogynous, usually united or clustered into 3 or 5 

 l^undles; anthers 2-celled. * Ovary consisting of 3 to 5 cai'pels moxQ or less 

 united, either 1-celled with the placentas on the intlexed margins of the car-

 Styles as many as carpels, free or rarely miited at the base, with terminal 

 stigmas. Ovules usually several to each cell or placenta," anatropous. Fruit
