WiTHANIA. 



This genus differs from Physalis in its fruticose habit, in its urceolate 

 caljrx, with long setiform teeth, enlarging with the growth of the fruit 

 into a campanular shape, with a wide, open mouth, and becoming cori- 

 aceous in substance, not resolving itself into a globular bladder-like 

 form, of thin reticulated texture, and concealing the berry. The corolla 

 also differs in having a short funnel-shaped tube, somewhat longer than 

 the tube of the calyx, with a border of nearly equal length, divided into 

 five linear erect teeth, with obtuse summits, the stamens dilated at base 

 and originating in a nearly annular adnate ring, the stigma is large and 

 capitate, or rather sub-bilabiate, with a large two-lobed gland enclosed 

 between the two rounded lobes. The embryo is helical and spiral, 

 consisting of a whorl and a quarter. It approaches Hypioticunt and 

 Pmieera in the form of its corolla, but it differs from them in the 

 structure and growth of its calyx.
