lobes exceeding the fruit. Corolla rotate, white, sometimes tinged 
with purple and generally ochroleucous or yellow in the center, 
3-4 cm. in diameter; limb plicate. Stamens inserted near the 
base of the corolla; filaments long and slender, anthers oblong, 
opening by a longitudinal slit. Style and stigma as in Physalıs. 
Seeds kidney-shaped, flattened, punctate. 
Only one species, hitherto included in Physalis, but all the 
characters of the corolla, as well as most of those of the calyx, 
point towards Chamaesaracha. The fruiting calyx however ex- 
eeds the fruit, and is, according to Prof. C. F. Wheeler, somewhat 
inflated at first. It is, however, never angled or ribbed as in 
Physalıs.
