77013. BAMBUSA sp. Bamboo. From Canton, China. Collected by F. A. McClure. A 

 dwarf, ornamental bamboo of the clump type. It was grown only in pots at Canton and 

 usually did not exceed 3 feet in height. Grown in the open at Savannah, Georgia, it 

 has reached a height of 12 feet. The ornamental value consists partly in the short- 

 ness and peculiar swollen character of the internodes of some of the culms. To the 

 latter is due the Chinese name "Fat t'o chuk," meaning "Budda's belly bamboo." One 

 large branch between 2 smaller ones arise from each node of the culms, with additional 

 still smaller ones later. The leaves are 1 to 3 inches long by 3/16 to 5/8 of an 

 inch wide. The foliage is little injured by temperatures down to about 26° F. and, 

 with heavy mulching, plants outside at Savannah have withstood 21° without serious 

 injury to the roots. For trial in the South Atlantic and Gulf coast regions. (Savan- 

 nah, Ga.) 



32474. BETULA DAVURICA. Birch. From Chosen (Korea). Presented by T. Watanabe, 

 Forest Experiment Station, Keijo. A tree up to 60 feet high, with wide-spreading 

 branches and purplish-brown flaky bark. The broadly wedge-shaped leaves, 2 to 4 

 inches long, are dark green above and have serrate margins. For trial in the northern 

 states. (Bell, Md.) 



82065. BETULA JAPONICA. Birch. From Chosen (Korea). Collected by P. H. Dorsett 

 and W. J. Morse, agricultural explorers. Bureau of Plant Industry. A hardy ornamental 

 tree, native to Japan, up to 75 feet high, with broadly oval leaves. It is related 

 to Be tula Eindula. For trial in all except the warmest and coldest parts of the 

 United States. (Bell, Md.) 



82066. BETULA JAPONICA. Same as preceding (No. 82065). (Bell, Md.) 



•76850. B0LUSANTHUS SPECIOSUS. Fabaceae. From Melbourne, Victoria, Australia. Pre- 

 sented by the Melbourne Botanic Gardens. A small, ornamental South African tree with 

 compound leaves and long racemes of violet flowers. It is very tender. The hard, 

 white, durable timber is used for wheel spokes. For trial only in regions practically 

 free from frost. (Chico, Calif.) 



63554. BOUGAINVILLEA WARSZEWICZII . Nyctaginaceae. From Algeria. Collected by 

 David Fairchild, agricultural explorer, Bureau of Plant Industry. A horticultural 

 variety of this gorgeous-flowering climber. Instead of flowering feebly all through 

 the season, this form bursts into bloom in the spring with a perfect mass of magenta 

 flowers which completely hide the plant, and then it does not flower again until the 

 following spring. For trial in southern Florida and southern California. (Bell, 

 Md.) 



32408. BR0MELIA PINGUIN. Bromeliaceae . Pinguin. From Rio Piedras, Porto Rico. 

 Presented by the Insular Experiment Station, Department of Agriculture and Labor. 

 A tropical succulent plant, 4 to 6 feet high, with spiny-margined leaves that turn 

 red with age. The reddish flowers are in dense panicles and the acid fruits, the 

 size of plums, yield a cooling juice. Native to the West Indies. For trial in south- 

 ern California and southern Florida. (Chico, Calif.)
