Descr. Stems erect, four-angled: the angles are acute

 from about the middle. Leaves generally opposite, some- 

 times alternate, quite entire, elliptical, smooth, sessile. 

 Flowers large, shewy, solitary, axillary, on very short 

 peduncles. Calyx nearly cylindrical, a little dilated upwards, 

 twelve-toothed ; six of the teeth subulate and longer, alter- 

 nating with other six minute and inllccted. Petals six, equal, 

 inserted into the margin of the calyx. Stamens six only, 

 inserted into the tube of the calyx near the bottom ; but 

 the smaller teeth of the calyx are powder) 1 , as if nature 

 attempted to convert them into other six anthers. Germen
