soil, near San Antonio and New Braunfels. May. — “ 'T'rail- 
ing on the ground. Root from six inches to three feet thick, 
fusiform, yellow inside.” Fruit yellow, globose, two or three 
inches in diameter.’ — This plant has been in cultivation in 
the Cambridge Botanic Garden for the last two or three years, 
from Texan seeds. It flowers freely, and has produced full- 
grown fruit, which, however, has not ripened. Our plants 
are diccious, but it is moncecious, according to Dr. James. 
It may be the Cucurbita feetidissima, H. B. K.,as Dr. Torrey 
long since suggested, but that plant is said to be an annual, 
like the rest of the genus; besides, ours is not fetid. In its 
calyx, gamopetalous campanulate corolla, exappendiculate 
anthers, and even in the tumid margin of the seeds (although 
said by Dr. James to be acute) it accords with Cucurbita. 
Mr. Fendler met with the plant at Santa Fe; Dr. Gregg, 
between Saltillo and Parras, and, according to Dr. Engel- 
mann, “ Dr. Wislizenus found the same plant in the moun- 
tains of Chihuahua, with pyriform fruit.”
