67509. THYRSOSTACHYS SIAMEN3IS . Bamboo. From India. Obtained from Frederico 

 Varela. Calcutta. This is the so-called "regal" bamboo of Siam, and as far as known, 

 has not been previously introduced into this country. The culms grow to a height of 

 35 to 40 feet, are very straight and do not branch until high up. It is said to be 

 one of the most graceful bamboos known. Its chief value will doubtless be in its 

 ornamental nature. Suitable only for the warmer coast sections of Florida, Porto 

 Rico and the Canal Zone. (Chapman Field, Fla.)
