Bamboo Possibilities in America: Mr. S. C. 



■SrtrNTZ. 



After a brief introductory statement outlining 

 the past history of bamboo introduction into the 

 United States, and sketching the present condi- 

 tion of bamboo planting in this country, atten- 

 tion was directed to the possible future uses for 

 bamboo. Furniture, basketry, especially for par- 

 cel post shipments, Venetian blinds and barrel 

 hoops were suggested as probable industries in 

 which bamboo would find use, while the develop- 

 ment for ornamental planting and as a possible 

 stock for paper was especially emphasized. Lan- 

 tern slides of bamboo plantations and uses abroad 

 and in the United States were shown, together 

 with a considerable exhibit of manufactured 

 bamboo articles. 

 Botany of Cacao and Patashte: Mk. O. F. Cook. 



The patashte tree is a relative of the cacao, 

 known to botanists under the name Theoiroma 

 iicolor Humboldt and Bonpland. It has di- 

 morphic branches like cacao, the lateral branches 

 being formed in whorls at the ends of the up- 

 right shoots, but only 3 laterals in a whorl, in- 

 stead of 5 or 6, as in cacao. Many other dif- 

 ferences in leaves, inflorescences and flowers were 

 shown. The inflorescences of patashte are con- 

 fined to new growth at the ends of the lateral 

 branches, while cacao is eaulocarpous, with all 

 of the flowers produced from the old wood on the 

 trunk and larger limbs of the tree. The vari- 

 ous features were explained with lantern-slide il- 

 lustrations, and the paper was followed by a brief 

 discussion of the question whether trees with 

 such numerous and definite differences should be 

 classified in the same genus.
