2. Petunia propinqua (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 inaequalibus, linearibus, erectis, 

 tubo corollse 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 

 ls little more than half the size of that of the former species.

This plant, now so extensively cultivated in our gardens 

 °n account of its great beauty, scarcely requires any observa- 

 fa on, but it may be remarked, that in the native species the 

 leaves are much smaller than in the cultivated specimens. 

 Several plants in Sir William Hooker's herbarium, collected 

 R ear the Rio Parana by Tweedie, which appear of the same
