Plania Lindheimeriana. 1S1 



ground. Leaves crowded. Leaflets an inch or less in 

 length, one to two lines wide, rather rigid, as long as the 

 petiole. Peduncle one or two inches long, slender. Corolla 

 two thirds of an inch in diameter, pale yellow in the speci- 

 mens. The seven perfect anthers open by a terminal pore ; 

 the three upper stamens are abortive, as in the section Cha- 

 maesenna, to which, so far as can be told in the absence of 

 the fruit, this species would seem to belong.

 — Rocky plateaus near New Braunfels, and on the Upper 

 Guadaloupe, not seen on the Pierdenales. July, in flower, 

 and with young fruit : August, with ripe fruit. — Shrub two or
