as long as the tube. Petals orbicular, nearly as long as the calyx-lobes. 
Stamens 5; filaments short; anther-cells distinct, globular, pendulous, fur- 
rowed, opening in short slits; connective-gland small. Ovules 2, erect, on 
a short basal placenta, in a very small cavity at the top of the adnate part of 
the calyx-tube. Fruiting-calyx slightly enlarged. Seeds usuall 2.— Backea
