80532. Pessea Americana Mill. (P. 

 ffratissima Gaertn. f.). Lauraceae. 



Avocado. 



From Waldo. Fla. Bud sticks presented by 

 C. C. Shooter. Received May 31, 1929. 



A tree about 50 feet high with an im- 

 mense trunk. It survived the freeze in 

 January. 1928, at which time the ther- 

 mometer went to 15° F. at Gainesville, and 

 the cold lasted several days. The tree, then 

 in full bloom, lost its leaves for the first 

 time, and the branches were cut back about 

 one-third. The smaller seedling trees did 

 not even lose their leaves when orange and 

 grapefruit trees were frozen to the ground. 

 It starts blooming in January and contin- 

 ues through until March, even if frost 

 catches it, and has had as manv as 1,000 

 fruits. 



80533 to 80539.

 tural Explorers. Bureau of Plant Indus- 

 try. Received May 31, 1929.

80535. Pisum sativum L. Fabaceae. Pea. 



No. 228. Endo. From the Tokyo 

 Seed, Plant & Implement Co., Konon, 

 May 6, 1929. A winter variety sown 

 during the early fall in the Tokyo dis- 

 trict. The pod's are used as a green 

 vegetable when the peas are just com- 

 mencing to form, and later the peas are 

 used. 



80536 and 80537. Soja max (L.) Piper 



(Glycine hispida Maxim.). Fabaceae. 



Soybean. 



80536. No. 134. From the Soy Sauce 

 Laboratory, Imperial Experiment 

 Station, Nishigahara, May 3, 1929. 

 The seeds were originally grown in 

 Manchuria. This sample is appar- 

 ently mixed and may consist of sev- 

 eral strains. It came from a lot 

 used in the manufacture of soy 

 sauce. 



80537. No. 212. Ryokuhi Da-izu. From 

 the Yamato Seed Co., Takadocho. 

 May 6, 1929. A small black-seeded 

 variety said to be used especially 

 as a green-manure crop. 



80538 and 80539. Yicia faba L. Faba- 

 ceae. Broadbean. 



80538. No. 211. Sora Mame. From 

 the Yamato Seed Co., Takadocho, 

 May 6. 1929. A variety grown in 

 the Tokyo district and southward. 

 When full grown the beans are 

 used after the manner of the green 

 Lima bean. The dried beans are 

 used in making candied beans by 

 boiling in sirup and they are also 

 roasted. 



80539. No. 216. Issum Sora Mame 

 (1-inch broad bean). From the 

 Yamato Seed Co., Takadocho, May 

 6, 1929. A variety grown exten- 

 sively for food in the Tokyo dis-

 during the fall. The beans are 

 used especially in making candied

80540. Peesea schiedeana Nees. Lau- 

 raceae. Coyo. 



From Tela. Honduras. Plants presented 

 by Alfred F. Butler. Horticulturist. Re- 

 search Department of the United Fruit 

 Co. Received June 3, 1929. 

 This plant, known as Yas in Costa Rica 

 and Coyo in Guatemala, occurs from 

 southern Mexico to Panama. In Costa 

 Rica it is found abundantly on the slopes 

 of Irazu at altitudes between 4,000 and 

 6,000 feet. The fruits greatly resemble 

 avocados. Up to the present the coyo has 

 not shown much promise in Florida or 

 California. It is somewhat slow of 

 growth and probably will not bear until 

 the trees are at least 8 or 10 years old. 

 Efforts are being made to introduce the 

 best seedling varieties from Guatemala and 

 to propagate them by grafting. In this 

 way it may be possible to encourage early 

 fruiting arid to have fruit of better qual- 

 ity than would be obtained from most seed- 

 lings.
