recommends young shoots of Bamboos as paper-material. The seeds 

 of Bambusa Tulda have been found by me to retain their vitality for 

 some time and to germinate readily. Opportunities should never be 

 missed of sending abroad fresh seeds of any Bamboos, whenever and 

 wherever such may ripen. 



Bambusa Blumeana, Schultes. 



Insular India. This Bamboo, with its spiny buds and pendant 

 branchlets, is according to Kurz one of the best for cattle-proof 

 live-hedges among the Asiatic species. In continental India B. nana 

 and B. arundinacea are much used for the same purpose. Periodic 

 trimming is required. 



Bambusa flexuosa, Munro. 



China. Only 12 feet high, but very hardy, having resisted in 

 Southern France a temperature of 8 F. [Geoffroy St. Hilaire]. 



Bambusa heterocycla, Carriere. 



China. One of the hardiest of all true Bambusas, with B. Cas- 

 tilionis. 



Bambusa nana, Roxburgh. 



China. This dwarf Bamboo is extensively utilized for hedges in 

 Southern Asia. 



Bambusa Oliveriana, Gamble. 



Upper India. A rather tall species which seeds freely. Likes a 

 moderately dry climate and a fairly open moist soil [Gamble]. 



Bambusa Senamensis, Franchet and Savatier. 



Japan. A tall and hardy species, distinguished from all other 

 Japanese Bambusaceae by its large leaves. Young Bamboo-shoots 

 (probably of several species) constitute part of the nourishment of all 

 classes in Japan [Dupont]. 



Bambusa spinosa, Roxburgh.* 



Bengal. A Bamboo attaining 100 feet in height. The central 

 cavity of the canes is of less diameter than in most other species ; 

 thus the strength for many technic purposes is increased. 



Bambusa vulgaris, Schrader.* 



The large unarmed Bamboo of Insular India. Height to 70 feet; 

 the stems may attain a length even of 40 feet in one season, though; 

 the growth is slower in cooler climes. It has proved to be capable of 

 resisting occasional night-frosts. It is the best for building bamboo- 

 houses. Immersion in water for some time renders the cane still
