SOUTH AMERICAN PLANTS. 61 



from the former species by its radical leaves, wliicli are of thicker 

 texture, broader in proportion, shorter and more elliptic, with 



incisures 



as in S. picta : the radical leaves, including the attenuated pe- 

 tiole, are 3^ inches in length, the limb being 2i- inches long and 

 11 hues broads 



Pteroglossis. 



Among the very curious and interesting plants collected by 

 Bridges in the vicinity of Coquimbo, is one that will constitute a 

 new genus, near Salpiglossis. It is a plant with pinnatifid leaves, 

 only in a few of the lower axils, those above being reduced to a 

 linear form; its ascending stems are widely diffuse in many 

 spreading dichotomous branchlets, which are very slender and 

 terete ; the leaves at each axil are gradually diminished to the 

 size of very short linear bracts, which support a few solitary one- 

 flowered peduncles. The corolla, though smaller, has much the 

 shape of that of Salpiylossis^ with didynamous included stamens^ 

 and it possesses the peculiar sestivation of the Salpiglossidea. 

 The most remarkable feature consists in the unusually broad ex- 

 pansion of its stigma, which hoods the lower pair of stamens, 

 somewhat after the manner of Nierembergiaj its winged appen- 

 dages being quite membranaceous, decurrent for some length 

 upon the style, and marked w4th numerous parallel radiating 

 nervures, which terminate in its lacerated or crenulate margins. 

 The name above proposed is derived from irrepovj ala, and 

 yXcoacra, lingua^ because of its broadly winged stigma.
