 YUCCA MOJAVENSIS Sargent. 



The datile, or wild date, of the Mexi- 

 cans, better known to Americans as the 

 Spanish bayonet, Mexican dagger 

 plant, wild banana, etc., occurs from 

 the Mohave desert to the vicinity of 

 San Quintin, Lower California, extend- 

 ing eastward through the arid regions 

 of Arizona and Sonora, and perhaps to 

 Texas. It attains almost tree-like pro- 

 portions, and forms extensive forest- 

 like plantations. Such a forest, when 

 in full bloom, is a sight to be remem- 

 bered. The large, waxy, bell-shaped 

 flowers, of a creamy, sometimes mark- 

 ed with prune purple, are of surpass- 

 ing beauty. The fruit does not seem 

 to mature well near the coast. It is 

 somewhat of the size and shape of a 

 banana, of a sweetish taste, slightly 

 reminding one of a fig. Near San 

 Diego the plant is commonly under 8 

 feet in height; in the interior attains 

 to 15 or 18 feet.
