507 
metres long, thin, somewhat repand-dentate or nearly entire ; peti- 
oles as long as.the leaves; corolla greenish-yellow with brown 
centre; fruiting calyx as in P. hederaefolia Gray, but of thinner 
texture. 
The validity of this as a species may be doubted. It is inter- 
mediate between P. heterophylla and P. hederaefolia and might be 
placed as a variety of either with about equal right. It, perhaps, 
most resembles the latter, but differs in the thinner texture of the 
leaves and the fruiting calyx, in the larger flower and in the long 
white hairs. 
The following localities are recorded : 
Nebraska: P. A. Rydberg, No. 269, 1891 (type). 
Kansas: E. Bartholomew, No. 2, 1892; E. A. Popenoe, 1875. 
Texes: G. Jermy, No. 618, 1890. 
“PHYSALIS VERSICOLOR Nn. sp. 
Finely pubescent, in age glabrate; stem from a stout perennial 
root, much branched, at first erect but later spreading, slender, ob- 
tusely angled; lower leaves reniform-cordate, the upper ovate, 
all more or less oblique at the base, sinuately toothed, 2-4 centi- 
metres long, on slender petioles which are generally a little longer 
than the blade; pedicels slender, about the length of the petioles ; 
calyx-lobes taiangular-ovate, shorter than the tube; flowers about 
I centimetre wide, yellow or drab with brown spots in the centre, 
turning bluish in drying; fruiting calyx thin, ovoid-cylindrical, 
reticulate, decidedly 10-angled, 2.5-3.5 centimetres long, gener- 
ally open at the mouth. 
The specimens collected within the United States are more 
erect, have larger leaves and fruiting calyces than the Mexican. 
Rare within the United States. , 
New Mexico: C. Wright, 1851 (Mo. Bot. Gard. herb.). 
Arizona: Treadwell, 1879 (Cal. Acad. Sci.). 
Mexico, Guaymas: Ed. Palmer, 621 and 622. 1887. 
“ PHYSALIS VERSICOLOR MICROPHYLLA N. var. 
Like the species, but leaves only about 1 centimetre long, del- 
toid, coarsely toothed, peduncles about twice the length of the 
leaves; fruiting calyx nearly spherical, 1.5 centimetres long, 
tinged with purple. 
Mexico, Guaymas: Ed. Palmer, No. 94, 1887 (herbaria of iB
