Cedar woods, in sandy and rocky soil, New Braunfels. May, 
June, in flower and fruit. — Plant, with much the aspect of 
G. Drummondii; but the leaves smoother, less toothed, and 
“longer petioled than any other ;” the stem villous or hirsute 
below with long spreading hairs, while the rachis, calyx, 
bracts, &c. are perfectly glabrous. ‘The petals appear to be 
paler than those of G. Drummondii, and the fruits are closely 
sessile, without any narrowed base or stipe. It is much 
more closely related to the Gaura tripetala, Cav. ; judging 
from Spach’s description, and from Texan specimens with 
triquetrous fruit and trimerous flowers, gathered by Mr. 
Wright, which agree well with the character.!

1 Gaura hirsuta, Scheele, in Linnea, 21. p. 580, described from specimens gathered 
by Romer between Bastrop and Austin, does not accord with the present species, 
but is likely to be either G. Lindheimeri or G. biennis. ‘G. Roemeriana of the same 
author, from New Braunfels, described without the fruit, may be safely referred to 
G. Drummondii.
