HALORAGE^. 



Hippuris vulgaris, L. Sp. PI. 4 (1753). 



Not at all common ; in a muddy bog in Lander, August 3, 1894 

 (No. 694). 

 Callitriche palustris, L. Sp. PI. 969 (1753). 



In shallow ponds and pools ; rather frequent.

 ley, August 25, 1895 (No. 1860).

ONAGRACE^. 



Epilobium adenocaulon, Hausskn. Oest. Bot. Zeitschr. xxix (1879), 

 Common about springs and wet places. 



Laramie, August, 1891, B. C. ButTum ; Whalen Canon, July 19, 

 1894 (No. 545); Lander Creek, August 31, 1894 (No. 1107). 

 Epilobium brevistylum, Barbey, Brewer & Wats. Bot. Cal. i, 220 

 (1876). 



This specimen I had called E. affine, but a closer study of text 

 and plate in Rev. Epilobium by Trelease leads me to believe that 

 these specimens belong to the above. 



Wind River Mountains, August 11, 1894 (No. 852). 

 Epilobium delicatum, Trelease, Mo. Bot. Garden Rep. ii, (1891). 



Of the two specimens before me, the one seems nearly typical, 

 the other is rather large flowered but too immature for close com- 

 parison.
