52427 to 52431— Continued. 



52431. Florida Green, from AV. B. Cross, Kreamer Island, Fla. In- 

 troduced for experimental purposes. 



" Presumably a medium-sized soft green cane identical with Otaheite 

 of Cuba and Bonrlion of the British West Indies. Variety low In 

 fiber and highly susceptible to most sugar-cane diseases. Liked for 

 a chewing cune but not well adapted for sirup or sugar because of 

 the lack of disease resistance and poor ratooning qualities." (P. A. 

 Toder.) 



52432 to 52435. Saccharum ornciNARUM L. Poacese. 



Sugar cane. 



From Rio Piedras, Porto Rico. Seeds presented by F. S. Earle, Insular Ex- 

 periment Station. Received January 15, 1921. 



52432. " ])-100. "A dark-red cane, originated in Demerara by Doctor 

 Harrison, fairly resistant to root disease and a fairly good ratooner. 

 Its dark color might make it undesirable for sirup-making. When 

 allowed sufficient time to mature, the cane tests well for sucrose and 

 purity." {H. B. Cowgill.) 



"A very good germinator." {R. A. Vive.) 



52433. " Eavangire (Uba). A slender fibrous variety of the northern 

 India (Japanese) type, very prolific and resistant to most diseases. 

 Imnmne to mosaic disease. Similar to or identical with Uba." {P. A. 

 Yoder.) 



52434. "P. R. 260. An erect-growing, green to yellowish green cane, 

 having long stalks of good girth, which gave excellent tonnage in 

 gran culUira (long period of growth — 18 months in Porto Rico) and 

 also made an exceptionally fine appearance at Central Guanica, where 

 it was sent for trial. The tonnage obtained from gran cultura was 

 excellent. It has ratooned only fairly well and will probably be 

 more suitable for the south coast, where ratooning is little practiced." 

 (H. B. Cowgill.) 



52435. " P. R. 292. A tall erect-growing cane, of reddish green color, 

 which gave an excellent yield as gran cultura, and a juice of good su- 

 crose and purity. The stalks were long and of good girth. It stooled 

 well and was vigorous and healthy. It also made a good growth as 

 ratoon cane." (Annual Report of the Porto Rico Insidar Experiment 

 Station, 1917-1918, p. 91.) 



62436 to 52448. 



From Bangkok, Siam. Seeds collected by J. F. Rock, Agricultural Explorer 

 of the United States Department of Agriculture. Received January 14, 

 1921. Quoted notes by Mr. Rock. 



52436. Castanea diveksifolia Kurz. Fagaceae. 

 "(No. 81. Chiengmai, Siam.)" 



A moderate-sized evergreen tree found in Nepal, eastern Bengal, 

 Assam, and Chittagoug up to an altitude of 5,000 feet. The fruit is 

 eaten and much resembles the filbert in shape and flavor but has a 

 thinner shell. The gray hardwood splits well and is largely used for 

 shingles in Darjiling. It coppices freely and is often pollarded and the 

 branches burned for fertilizer. (Adapted from 'Watt, Dictionary of the 

 Economic Products of India, vol. 2, p. 228.)
