all woods, lighter even than cork. In Trinidad 

 and other places it forms an article of commerce with 

 fishermen, who use it in place of cork on their nets.

PhyllGdadiis triehomanoides (Taxaceae), 47573. From 

 Auckland, New Zealand. Seeds presented by Mr. James 

 W. Poynton. "Cones of the remarkable ' celery- topped 

 pine'; native name 'tanekaha.' The bark contains two 

 valuable red dyes and about 22 per cent of tannin. 

 When about 18 months old the leaves become aborted and 

 the leafstalks expand, become leaflike, and take on 

 all the functions of leaves, as do some of the acacias, 

 but I believe the 'tanekaha' is the only pine with 

 this habit." (Poynton.) 



Pruniis serrulata (Amygdalaceae) , 47567. Flowering cherry. 



From Chevy Chase, Md . Seeds collected by Dr. David 

 Fair-child at his home, "In The Woods." "'Daizen.' 

 Seeds from a tree at the southeast corner of my study. 

 This tree and, in fact, all the other 'Daizen' trees on 

 my place, have characterized themselves by their regular 

 fr iting habit, the cherry fragrance of their single 

 white flowers, and the vigor of their trunks and freedom 

 from suckers. They have been particularly free from 

 disease and have struck me as promising for stock 

 purposes. These trees were bought originally from the 

 Yokohama Nursery Co., Yokohama, Japan, in the spring 

 of 1906, and are now 13 years old and 20 feet or so 

 high with trunks about 6 inches in diameter. It is 

 possible of course that the plants from these seeds 

 will show the result of crossing with other of the 

 varieties such as 'Murasaki,' 'Jobeni,' and 'Naden,' 

 with which they are closely planted." (Fairchild.) 



The tree has made thrifty growth at Boise, Idaho, 

 and at San Jose and Herman, Calif. 



Primus subhirtella autumnalis (Amygdalaceae), 47534. 

 From Chevy Chase, Md. Seeds collected by Dr. David 

 Fairchild, at his home, "In The Woods." "Seeds from 

 a tree of the 'October-blooming' Japanese flowering 

 cherry imported from the Yokohama Nursery Co., Yoko- 

 hama, Japan, in 1906. I suggest it as a stock for 

 commercial cherries because of its unusual vigor, the 

 fact that its trunk has been very free from disease, 

 that it does not sucker, that its seedlings are not 

 subject to the usual leaf blight ( Cylindrosporium padi ) ,
