New Mexico: Thurber, 1851; Wright, no. 1597 and no. 1600,

> A form with shorter and denser pubescence and more de- 
-cumbent habit is var. puberula Gray. It is only represented by 
the following specimens: 
Texas: Wright no. 528, in part (type); Buckley; V. Hav- 
ard, nos. 170 and 171, 1881. 
Another form with slightly longer peduncles and more acutish 
leaves, which are scarcely cordate at the base, is P. Palmeri Gray, 
l. c. It forms a transition to P. Fendleri cordifolia. The only 
specimens representing this form are: 
New Mexico: H. H Rusby, no. 756, 1881. 
Arizona and California: E. Palmer, no. 430, 1876; (type of 
P. Palmeri Gray). 
Mexico. C. G. Pringle, no. 15, 1885; Gregg. 
In my opinion they scarcely deserve varietal rank. 
, 27. Physalis rotundata. 
P. hederaefolia Holzinger, Cont. U. S. Nat. Herb. 1: 212. 1892. 
iffuse and spreading, much (generally dichotomously, zigzag) 
branched, from a perennial rootstock, densely and finely viscid- 
pubescent, generally more glandular than er DEEN leaves 
nearly orbicular with more or less cordate base, 2-4 cm. in diame- 
ter, with much smaller teeth than in P. (ere Setiolés short, 
more or less winged; peduncles short, in fruit p more than 
half the length of the calyx ; corolla 1 7, cm. in diameter, greenish 
yellow with | brownish center ; fruiting calyx ovoid, RER is 
not sunken at the base. 
It is very near the preceding species and perhaps only a 
variety thereof, but as it has a distribution distinct from that of 7. 
hederacfolia, the ranges overlapping only little, it seems advisable 
to treat it separately. Itcan always be distinguished by its spread- 
ing habit, its smaller more rounded and less toothed leaves, and its 
more glandular pubescence. The following specimens are in our 
herbaria :
