genera. Physalis grandiflora Hook is made the type of a new 
genus. It rather belongs to Chamaesaracha than to Physalis. It 
lacks the essential characters of the latter. The fruiting calyx is 
neither angled, nor ten-ribbed, nor reticulate. It is thin, indis- 
tinctly veined, closely fitting to the fruit and open at the mouth. 
The only floral character which differs from Chamaesaracha nana 
is the length of the calyx-lobes, which much exceed the fruit. 
The corolla of P. grandiflora is that of a Chamaesaracha, 1. e., 
widely rotate and white, or sometimes tinged with purple. In 
Physalis the corolla is open-campanulate rather than rotate and 
with a few exceptions more or less yellow. Evidently P. grandi- 
flora should be removed from Physalis. As it is so nearly related 
to Chamaesaracha nana (differing, as I thought, principally in the 
length of the calyx), I transferred it at first to that genus, but 
have decided at last to make it the type of a new one. I have 
so decided mostly from the fact that the calyx is at first 
somewhat inflated, a character never found in Chamaesaracha. 
This is not seen in herbarium specimens, but my authority is 
Prof. C. F. Wheeler, of Michigan Agricultural College, who 
knows the plant in the field. 
Physalis lobata is also taken out of the genus. It comes nearer 
to Chamaesaracha than to Physalıs in every respect except 
in the fruiting calyx. It differs however from both genera in the 
structure of the seeds, in the color and form of the corolla and in 
being somewhat fleshy. It is the type of a distinct genus. 
If two more of the species, P. microphysa and P. Alkekengt 
could be also removed, the genus would be a very natural 
one. In the former the fruiting calyx is nearly that of an 
Athenaea, while the corolla is of a true Physalis. In P. Alke- 
kengi, the corolla is whitish and much deeper cleft. If held dis- 
tinct from Physalıs, it would together with P. Sendtneri constitute 
a genus (Megista Tourr.) of European origin, while PAysalis proper 
is principally American. 
The genera included in the monograph all belong to the tribe 
Solaneae: Corolla (mostly short) with regular limb plicate or 
valvate in the bud, usually both, z. ¢., the sinuses or what answ 
to them plicate and the edges of the lobes induplicate. Stam 
(normally 5) all perfect. Fruit baccate or at least bee
