shallow ; anthers about one-fourth the length of the corolla, oblong, 
not tapering upward; fruiting calyx round-ovoid, of about the 
same size as in the preceding. 
Dr. Gray includes in this, Berlandier’s no. 2277, which Dunal 
refers to Physalis divaricata. These specimens do not belong to M. 
solanaceus, as they differ both in habit and leaves. There are two 
sheets from the original collection in the Torrey Herbarium and 
neither in flower. It is doubtful to which genus they belong. 
Very likely Dunal’s determination was correct. M. solanaceus 
occurs from Texas to Arizona and Mexico. Specimens examined: 
New Mexico: Bigelow, 1851 (Mex. Bound. Surv.); C. Wright, 
no. 1603, 1851-2 ; H. H. Rusby, no. 307, 1881 (in part). 
Arizona: T. E. Wilcox, 1883. 
Mexico: C. G. Pringle, no. 1079, 1886; no. 342, 1885. 
3. Margaranthus purpurascens n. sp. 
Stouter than the preceding, which it resembles; leaves broadly 
lanceolate, acuminate, thin, subentire, tapering into a slender peti- 
ole; peduncles very short; calyx campanulate-cylindrical, much 
larger than in the preceding, fully two-thirds the length ofthe corolla, 
.. lobes short-triangular; corolla yellowish, tinged with purple, with 
longer cylindrical portion; upper portion not fully as round as in 
the preceding, more tapering upward, but not as much con- 
stricted as in M. fenuis; lobes short, sinuses broad and shallow, 
anthers less than one-fourth the length of the corolla, oblong; fruiting 
calyx ovoid, 15-20 mm. long and 12-15 mm. in diameter, gener- 
ally purplish at the base and purple-veined. 
It differs from the preceding mainly in the stouter habit, in the 
. form of the corolla, and in the form and size of the calyx. 
Type specimens: : 
New Mexico: H. H. Rusby, no. 307, 1881. (mainly). 
4. Margaranthüs Lemmoni Gray, Proc. Am. Acad. 19: 91. 
1883; Syn. Fl. 2: part 1, 437. 
Very much branched and decumbent, more leafy than M. 
solanaceus which it much resembles ; leaves entire ; calyx cam. 
panulate, teeth half as long as the tube; corolla white, campanulate- 
urceolate, scarcely constricted at the orifice, which is obtusely 5- 
lobed ; fruiting calyx as in M. solanaceus. 
The only specimens extant, as far as 1 know, are those of the 
original collection, which I hastily looked at, while studying the
