 College of Agriculture, University of Nanking. Received April 15, 1922. 



A wild pear from the mountains of western China, where it grows at alti- 

 tudes of 1.000 to 1..500 meters (3.300 to 5.000 feet). This i^ear maintains a 

 vigorous and healthy condition under the most trying situations and may 

 prove to be a very valuable blight-resistant stock.

"Found at very salty places in the Sahara." (Trabut.) 



A low, much-branched, rigid, perennial grass from the Mediterranean coun-

 close to salt water. (Adapted from Muschler, Manual Flora of Egypt, vol. 1, 

 p. 129.) 



55030. Citrus sp. Eutacete. 



From Holguin. Cuba. Seeds presented by Thomas R. Towns. Received 

 Anril 11, 1922. 



•* I have used this shaddock, which is the nonedible white variety, as a stock 

 for 20 years and would be lost without it. For grapefruit it is inclined to gum 

 rather more than the sour orange or rough lemon, but my 10-year-old tan- 

 gerines, worked on this stock, have 2,500 fruits on some of the trees, and the 

 fruits are fine grained and of good commercial size. The Washington Navel 

 on this stock is also very prolific and bears a full crop every year, and I have 

 had equal success with other round oranges like the King, Valencia, Pine- 

 apple, and Lue Gim Gong." (To^cns.) 



55031 to 55039. Avena sativa L. Poaceae. Oats. 



From Helsingfors, Finland. Seeds presented by Leslie A. Davis, American 

 consul, through E. G. Montgomery, United States Department of Com- 

 merce. Received April 15, 1922. Quoted notes by Mr. Davis. 



55031. "L'sfl (0644). A white oat." 



55032. " Jalostettu maatiais (0144). This variety was obtained by cross- 

 ing the Kuopio 091 variety with the Guldregn variety. Its kernel 

 is very dark brown, resembling that of the native stock. It has simple 

 requirements and grows here just as well as native stock. The panicle 

 is large and beautiful. The straw is of average length, somewhat 

 better than that of native stock, but not so strong as that of the 

 Guldregn variety. It ripens at the same time as central Finnish native 

 stock, but five days earlier than the Guldregn variety. During experi- 

 ments of many years it has often given a better crop than the Guld- 

 regn variety and a considerably better one than native stocks, with 

 which it has been compared." 



55033. '' Kultasade (Guldregn). This variety from southern Finland 

 thrives in northern Finland only in high warm places." 



55034. " Nopsa (0206). This is a cross between the Norbotten and 

 Ligovo oat varieties. It has a large black chaffy kernel of which the 

 hull forms a considerable percentage. The panicle is not thick and 

 the stalk is strong. It is very early, ripening two weeks before the 

 Guldregn oat. The crop is good, considering its early ripening, but
