GREENMAN. — MEXICAN PLANTS. 311 



S. Palmeri, Rose, as shown by the calyx characters and by the general 

 habit, but tbe former differs conspicuously from the latter by the presence 

 of a dense tomentum over the entire lower surface of the leaves. The 

 examination of a considerable number of specimens of S. Palmeri shows 

 minute tufts of pubescence along the midrib on the lower surface of the 

 leaves, otherwise the foliage is perfectly glabrous. This character seems 

 to be fairly constant, and as no intergrading forms have yet been seen, it 

 seems best to the writer, for the present at least, to regard Mr. Pringle's 

 plant as a distinct species. 



Physalis acuminata. Suff rutescent : stems rlichotomously branched, 

 glabrous below, glandular-viscid above: leaves single or in pairs, ovate, 

 4 to 10 cm. long, 2 to G cm. broad, acuminate, acute, entire, narrowed 

 below into a slightly marginate glandular-viscid petiole, more or less 

 glandular-pubescent upon both surfaces especially upon the midrib and 

 veins beneath : pedicels 1 to 2 cm. long, later usually reflexed : calyx in 

 anthesis 1.3 cm. long, densely glandular-pubescent ; lobes ovate, acumi- 

 nate : corolla large, 2.5 to 3 cm. in diameter when fully expanded, siuu- 

 ately 5-lobed with short acutish lobes, and very shallow sinuses, ciliate, 

 conspicuously maculate in 5 areas with numerous dark purple spots, 

 densely pubescent at the base: filaments about equal, glabrous; anthers 

 purplish: fruiting calyx ovate, about 4 cm. long, equally 10-angled ; 

 lobes convergent: berry 2 cm. in diameter, glabrous. — Collected by 

 C. G. Pringle on the Sierra de las Cruces, State of Mexico, 23 October, 

 1892, no. 5315. Mr. Pringle's plant was at first doubtfully referred to 

 P. glutinosa, Schl., but from this species it differs materially in the char- 

 acter of the foliage. The leaves are all entire and narrowed below into 

 a petiole, not cordate, and, moreover, the fruiting calyx is equally 10- 

 angled, not 5-angled as in P. glutinosa. To P. Pringlei the plant under 

 consideration bears a strong superficial resemblance, but differs in having 

 the leaves all entire, and in the character of the fruiting calyx. 



Physalis Pringlei. • Suffrutescent : stems 1 to 1.5 in. long, more or 

 less branched, below terete, glabrous or nearly so, above and throughout 

 the younger parts densely glandular-viscid : leaves single or in pairs, 

 ovate to ovatedanceolate, 3 to 8 cm. long, two-thirds as broad, more or 

 less acuminate, acute, remotely sinuate-dentate or sublobate to subentire, 

 narrowed at the more or less unequal base into a slightly winged petiole, 

 glandular-viscid upon both surfaces: pedicels 1 to 1.5 cm. in length, at 

 first erect or at least ascending, later reflexed : calyx during anthesis 7 

 to 9 mm. long ; lobes ovate, atteuuate, about equalling the tube : corolla 

 about 2 cm. in diameter, repandly rotate, ciliate, conspicuously maculate
