Plante Lindheimeriane. 5 
capsula ovato-conica calycem vix superante uniloculari; se- 
minibus flavis longitudinaliter costatis. —Clayey ‘soil in pine 
woods near Houston. June. Also in Louisiana, Arkansas, 
&c. not uncommon. This is the plant mentioned in Torr. 
& Gr. Fl. N. Amer. under H. mutilum. It appears so 
different from the ordinary form of that species, that we are 
obliged to separate it. It varies from 6 to 20 inches in 
height.

which the carpels of the present species differ by their shorter 
and blunter horns, reticulated sides, and by the tooth project-
