The tallest of the bamboos, a native of the Malay Peninsula but much cul- 

 tivated in Burma, where it is known as wabo and in Assam as worra. It is 

 used in Burma for posts and rafters in house building, for carts, and for 

 joints for pails, boxes, flowerpots, etc. The large culms are often 120 feet 

 long and 25 to 30 inches in circumference. Extra fine culms are cut into short 

 lengtlis and prepared as umbrella stands. 



The rapid growth of this strikingly handsome bamboo was tested in the 

 botanig garden at Buitenzorg, Java, where the plant grew, on the average, 

 7.7 millimeters per hour by day and 13 millimeters per hour by night. One 

 culm grew 57 centimeters in 24 hours. (Adapted from Watt, Comtnercial 

 Products of India, p. 101, and Schimper, Plant Geography, p. 216.)

 "(No. o97a. June 18, 1920.) Seeds of a slender climber from the 

 mountains near San Pablo Tarrazu, elevation about 5,500 feet. Its 

 trifoliolate leaves, vhich are borne upon slender wiry stems, suggest 

 those of the common bean {Phaseolus vulgaris), and its seeds are strik- 

 ingly similar to those of A'tr^s precatorius, the crab's-eye of the West 

 Indies ; they are small, and bright red with a black eye. Of interest 

 chiefly for its seeds."
