 altitude of 11,000 feet, by Walter Koelz, Bureau of Plant Industry. An attractive 

 perennial for the border, with its few, bright glossy green, basal leaves that turn

 Bureau of Plant Industry. A tender herbaceous perennial of twining habit. The el- 

 liptical leaves are alternate, light green, and twisted on the petiole so that the 

 morphologically lower surface becomes the upper surface. The bonareas are closely 

 related to the genus Alstroemeria, from which they differ chiefly in their climbing 

 habit. The large showy flowers are variously colored and spotted, and a,re produced 

 in early spring or summer in pendulous umbels. For trial as conservatory plants 

 and in shady positions in the warmest parts of Florida and California. (Glenn 

 Dale, Md.)

 Presented by the Botanic Garden, Nanking. An herbaceous perennial related to Digi-
