 base. 1 Higher is inserted a thick coriaceous gamopetalous corolla 

 detached circularly by its base at anthesis, and falling in like a sort

of cone, dome, or cap. In its upper part alone from two to four small 

 unequally imbricated teeth are seen, but sometimes with great diffi- 

 culty, representing the free summits of the petals. The stamens are 

 inserted immediately above the corolla, with which they have no 

 adherence. They are each formed of a filament united, at the base 

 only, with the neighbouring filaments in most of the species, and of 

 a two-celled introrse anther dehiscing by two longitudinal clefts.

 the posterior and the anterior. This latter 

 may perhaps also represent the axile bract of 

 the flower raised to its receptacle upon the 

 pedicel ; in that way the calyx would only be 

 composed of three leaflets.
