APPENDIX G. — BOTANY. 273 



LOASACEjE. 



Mentzelia otjda, Torr. and Gr., Fl. 1, p. 535 ; Gray, PI. Fend]., p. 47, and 

 PI. Wright. 1, p. 73 ; Bartonia nuda, Nutt. Gen. 1, p. 297. Witchita Mount- 

 ains ; fl. June 22. 



CUCURBITACEiE. 



Cccurbita perennis, Gray, PI. Lindh. 2, p. 193 ; and Wright. PI. 2, p. 60. 

 Cfoetidissima, H. B. and Kunth? Cite umis perennis, James, in Long's Exped. 

 2, p. 20 ; Torr. and Gr. Fl. 1, p. 543. North Fork of the Platte ; fl. June 6. 

 Although the cultivated plant seems to be dioecious not unpleasant to the smell, 

 Mr. Wright says, (vide Gray, 1. c.) that in a wild state it is " certainly monoe- 

 cious, and exhales an unpleasant smell when bruised ;" so that it does not differ 

 from the description of C.fatidissima, except that the latter is said by Kunth to 

 be an annual, which may be a mistake. The flowers are as large as those of the 

 common pumpkin. 



Sicydium, sp. nov? Fruit 1| inch in diameter, globose, sessile. Seeds | 

 larger than in S. Lindheimeri, and more turgid. On the Main Fork of Red 

 River; fr. July 11. 



GROSSULACE^. 



Ribes aureum, Pursh, Fl. 1, p. 164 ; Torr. and Gr., Fl. 1, p. 552. North 

 Fork of Red River •, fr. June 4. 



UMBELLIFERJE. 



Eryngium diffusum, Torr. in Ann. Lye. N. York, 2, p. 207 ; Torr. and Gr., 

 Fl. 1, p. 603. Witchita Mountains ; fl. June 14. This rare species has not 

 been found before, since it was first discovered by Dr. James, more than thirty 

 years ago. It is rather doubtful whether it is diffuse, except, perhaps, when it 

 is old. The specimens of Captain Marcy are less branched than the original one 

 from which the description in the Flora of North America was drawn. 



Leptocaulis echinatus, Nutt., in DC. Prodr. 4, p. 107 ; Torr. and Gr., Fl. 

 1, p. 609. Headwaters of the Trinity ; April 2. 



Polyt^enia Nuttatlii, DC. Umb , p. 53, t. 13, and Prodr. 4, p. 196 ; Torr. 

 and Gr., Fl. 1, p. 533. Middle Fork of Red River; fl. June 1. Witchita
