maining dry during great part of the year. At five o'clock 

 we encamped, having travelled twenty-six miles due east. 

 The hunters were immediately sent out, but returned with- 

 out g?me, having seen nothing. 



A beautiful white flowered Gaura,* had been for several 

 days observed along the bank of the river. It is undescribed, 

 and has, before flowering, a very distinct resemblance to 

 common flax. 



* G. linifolia, Nuttall's manuscript. 



Stem erect, sparingly branched, smooth. Leaves smooth sessile, alter- 

 nate linear lanceolate entire, with the midrib translucent. Flowers in a 

 terniual crowded spike; after flowering, the spike extends itself, and in 

 the ripened fruit is scattered. Nut triquetrous, much shorter than the linear 

 bractea. 



The flowers are white, having in the calyx a tinge of brownish purple. 

 They are about as large as those of G. coccinnea. The plant is three or four 

 feet high, the leaves small and short, and the stem slender. 



This is the fifth species of Gaura, we have met with west of the Mississip- 

 pi. The G. biennis of the Eastern States, has not hitherto been found here.
