2. Petunia propingua (n. sp.) ;—herbacea, viscido-pilosa, cau- 
libus plurimis prostratis, demum adscendentibus: foliis 
lanceolatis, acutis, basi in petiolum longum spathulatis, 
floralibus consimilibus, oppositis: pedunculis solitariis 
elongatis, calycis laciniis ineequalibus, linearibus, erectis, 
tubo coroll calycem multo excedente, limbo campanulato, 
5-lobo, lobis brevibus, rotundatis.—Buenos Ayres. v. v. 
This plant is very near the former, and probably may 
be only a variety, but it is certainly different in ap- 
pearance, and in the shape of its floral leaves: it seldom ex- 
ceeds a foot in height, and is less pubescent, the stems being 
rounded, and slightly striate: the leaves are smaller, being 
(inclusive of the lengthened petiole) only 12 lines long and 3 
lines broad: the pedicels are 2 inches long, the calyx, 6 lines, 
divided half way down into 5 unequal, linear, obtuse, erect, 
and not foliaceous lobes: the tube of the corolla is 2 inches 
long, slender, cylindrical in the lower portion, funnel-shaped 
above, swelling into a bell-shaped mouth, the lobes of the 
border being short and rounded, the whole is of a dull white 
colour, slightly pubescent, and marked with 5 longitudinal 
purplish lines: the stamens, which are included, are of 
unequal length, one being shorter than the rest : the capsule 
is little more than half the size of that of the former species.

This plant, now so extensively cultivated in our gardens 
on account of its great beauty, scarcely requires any observa- 
tion, but it may be remarked, that in the native species the 
leaves are much smaller than in the cultivated specimens.

near the Rio Parana by Tweedie, which appear of the same
