 leaves. Cm: of 1 petal, wheel-shaped, in 7 deep, spread- 

 ing, elliptic-lanceolate, nearly equal, segments, alternate 

 with the calyx, very slightly connected. Filam. capillary, 

 spreading, the length of the calyx, shorter than the co- 

 rolla, inserted into the base of each segment. Anth. ter- 

 minal, oblong, recurved. Germ, globose, superior. Style 

 cylindrical, rather swelling upwards, the length of the 

 stamens. Stigma obtuse. Caps, globose, of 1 cell, and 7 el- 

 liptic-oblong valves, rarely fewer, shorter than the calyx, 

 with obtuse recurved points. Seeds few, roundish, some- 

 what angular at the inner side, each invested with a lax,
