genus Physalis at Harvard University. They seemed to me 
scarcely distinguishable from M. solanaceus, except in the form of 
the corolla, which approaches that of Physalis in form. Perhaps 
it is only a form of M. solanaceus.

ual or perennial herbs, sometimes a little woody below, with 
entire or sinuately toothed leaves. Peduncles slender, generally 
Wrightii and P. Carpenteri) in fascicles of 2-4. Calyx Gergen 
ulate, 5-toothed, in fruit enlarged and bladdery-inflated, mem- 
branaceous, 5-angled or prominently 10-ribbed and reticulate, 
wholly die in ulpy berry; teeth in most cases connivent. 
Corolla yellowish or whitish, often with a darker, brownish or pur- 
plish center, openly campanulate or rarely campanulate- -rotate, 
plicate, with very short and broad lobes which are slightly imbri- 
cate in the bud. Stamens inserted near the base of the corolla; 
anthers oblong, opening by a longitudinal slit. Style slender, 
somewhat bent; stigma minutely 2-cleft. Seeds numerous, kid- 
ney-shaped, flattened, with a thin edge, finely pitted. 
Physalis is principally an American genus. One section (Me- 
gista), consisting of two species, is of European origin, and about 
half a dozen are natives of India and Australia. The rest are 
American,* although several have been introduced into the Old 
World and Australia. The number of recognized species is about 
50. The actual number is, however, much larger as there are 
many yet to be described. Mexico is especially rich in species 
and of those native to that country perhaps more than one-half re- 
main unnamed. 
* Photographs, one half natural size, have been taken of all North American spe- 
cies and varieties of Physalis except P. Texana and P. Neo-Mexicana. Insome cases 
interesting forms have been added. What makes the set more valuable is that it in- 
cludes the photographs of all type specimens preserved in American herbaria, except 
that of P. angustifolia, which is a mere fragment, The photographs number about 
60, and may be had at about 15 cents each, either from Dr. Chas. E. Bessey, Univer- 
sity of Nebraska, or from the author.
