CUCURBIT A PALMATA S. Watson. 



Cucurbita Palmata Watson. — The 

 mock orange and wild pomegranate are 

 names frequently applied to this and 

 other species of the genus cucurbita. 

 The root is very bitter, and a strong 

 and quick emetic, acting "without any 

 disagreeable effect on the nerves." In 

 common with the following species this 

 is known to the Mexicans as "Chili 

 Coyote," or "Calabazilla." 



Cucurbita Foetidissima, H. B. K. — 

 I do not know that the natives dis- 

 criminate between these species in fa- 

 vor of either one or the other. "The 

 macerated root is also used as a rem- 

 edy for piles" (Watson, Bot, Cal., 

 i:239). 



C perennis G. daft, cv4 109 



Micrampelis Macrocarpa Greene. — 

 The chilocothe vine, also belonging to 

 the Cucurbitaceae, possesses similar 

 properties to Cucurbita palmata. The 

 fool "tn'n- immense size, and is cred- 

 ited with having formed the basis of 

 the once famous "Dr. Walker's Cele- 

 brated California Vim -.gar Bitters."

CACTACEAE. 

 Many people who have been acquaint- 

 ed only with the prickly pear and the 

 cholla cactus of the plains — perhaps 

 to the detriment of their epidermis, will 

 be surprised to learn that over one 

 thousand valid species exist, to which 

 more than three thousand names have 

 been applied by botanists and horti- 

 culturists.
