orbicular, rounded-obtuse or acutish at the apex, shorter than 

 the anther-cells; appendages linear-filiform, nearly straight, 

 about 5mm. long. Ovary ovoid, glabrous; style slightly 

 exceeding the anthers, gradually enlarged above, geniculate 

 below; stigma truncate, subdeltoid. Capsule (immature) ellip- 

 soid, glabrous. Flowers April.
