I. EUPHYSALIS. 
I. Pubescentes : Annuals; root much branched, generally weak; fruiting calyx 
sharply 5-angled, more or less acuminate at the summit, and sunken at the base; 
calyx-lobes (at flowering time) lanceolate or acuminate, as long as the tube or 
longer; plant somewhat villous or viscid pubescent (except in P. Barbadensis 
obscura). 
. Physalis subulata Rydb. Bull. Torr. Club, 22: 306. 
Annual from a branching root, erect, dichotomously beasties, 
2-4 decimeters high, stem angular and striate ; leaves round-ovate, 
somewhatobliqueat the base generally coarsely dentate ; peduncles 
shorter than the small corolla, which is 2-3 millimeters in diame- 
ter; calyx- -lobes shorter than the corolla, ending in a subulate 
acumination ; xis calyx sharply angled and purple-veined, 
heart-sha aped i in section 
This is Rad between P. Barbadensis and the South 
Mexican P. micandroides Schlecht. From the former it differs in 
the more glandular pubescence, and the long acumination of the 
calyx-lobes; from the latter in its smaller rounder leaves, in its 
calyx-lobes, which are shorter than the corolla, and in the fruiting 
calyx, which is smaller and not of a firm texture.* 
P. subulata has not yet been collected within the United States, 
but comes near to its border. 
Mexico, State of Chihuahua: C.G. Pringle, no. 1344, 1887 
(tvpe) It is in the following herbaria: Columbia University; 
Harvard University; College of Pharmacy, New York City; Uni- 
versity of Minnesota, and Professor Greene.

* Another related Mexican species is P. hirsuta Mart. & Gal., not Dunal. It dif- 
fers from P, subulata in its larger, less veiny fruiting calyx, from P. sicandroides by 
the calyx, which is not of a firm texture, and from both by its subentire leaves. 1t 
most resembles Z. pubescens, but differs in its subulate calyx-tip 
+ These references apply also partly to P, Barbadensis iud y pruinosa.
