On the genus WrrHANIA ; by Jous Miers, Esq., F.R.S., F.L.S., Xe. 
WITHANIA. : 
This genus differs from Physalis in its fruticose habit, in its urceolate 
calyx, 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 tecth, 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 Hypnoticum and 
Puneera in the form of its corolla, but it differs from them in the 
structure and growth of its calyx.
