52568. Pyrus ussuriensis Maxim. Malacese. Pear. 



From Yokohama, Japan. Seeds purchased from the I'okohama Nursery 

 Co. Received February 28, 1921. 



A Chinese pear stock recently discovered by Prof. F. C. Reimer, of the South- 

 ern Oregon Experiment Station, to be the most resistant to the blight which 

 attacks and destroys the trees. (Adapted from Yokohama Nursery Co., 

 Descriptive Catalogue for 1920, p. 55.)

52569. Eugenia uniflora L. Myrtacese. Pitanga. 



From Porto Alegre, Rio Grande do Sul, Brazil. Seeds presented by G. S. 

 Froes. Received January 12, 1921. 



The pitanga is the best of the Eugenias. It is grown to some extent in 

 Florida and California, but it has not been given the attention it deserves. 

 No horticultural varieties have been established, since the tree is rarely propa- 

 gated vegetatively, although there is considerable variation among seedlings.

52570. Taiwania cryptomerioides Hayata. Pinacese. 



From Jamaica Plain, Mass. Plants presented by Prof. C. S. Sargent, 

 director, Arnold Arboretum. Received March 1, 1921. Collected origi- 

 nally by E. H. Wilson. 



The loftiest tree in the forests of Taiwan is the Taiwania, which rears its 

 small moplike crown well above all its neighbors. The average height of this 

 tree is from 150 to 180 feet, but specimens exceeding 200 feet are known. The 

 trunk is sometimes as much as 30 feet in girth, quite straight, and bare of 

 branches for 100 to 150 feet. It is a strikingly distinct tree, singularly like 

 an old Cryptomeria ; both trees suggest gigantic lycopods. In the dense forests 

 the crown is small, dome shaped or flattened, the branches few and short, and 

 one wonders how so little leafage can support so large a tree. When the top 

 is broken by storms, the lateral branches assume an erect position. In the 

 more open forest the branches are massive and wide spreading, the crown is 

 oval or flattened, and on small trees the branchlets are often pendent. The 

 Taiwania sheds its small branchlets as do Cryptomeria, Cunninghamia, and 

 Sequoia. (Adapted from Jotimal of the Arnold Arboretum, vol. 2, p. 35.)

62571 to 52573. 



From Kulara, via Cairns, Queensland. Seeds presented by J. A. Hamilton. 

 Received February 24, 1921. Quoted notes by Mr. Hamilton. 



52571. MusA sp. Musaceffi. Banana. 

 "Wild banana." 



52572. PiPEB sp. Piperacese. Pepper. 

 " Wild pepper seeds. A very ornamental vine with very good fruits ; 



it likes rich alluvial soil and plenty of moisture in the growing season. 

 Of course it will not stand much frost, but as it is uninjured by the 

 few frosty nights here the plant should thrive in southern California." 

 Received as P. hanaroftii, for which a place of publication has not 

 yet been found. 



52573. (Undetermined.) 



"A pretty tree which grows in alluvial soil near creeks; it bears 

 prolifically very acid fruits which make a good preserve."
