Betula spp. (Betulaceae . ) 39989-991. Seeds of Japanese 

 birches received from the Arnold Arboretum, from the col- 

 lections of Mr. E. H. Wilson. Betula schmidtii Regel, a 

 stately tree from southeastern Manchuria, B. pendula ja- 

 ponica Miq. , and B. ulmifolia Sieb. & Zucc., a native of

Castanopsis sp. (Fagaceae.) 39909. Cuttings from near 

 Pao dji, Kansu, China. "A small tree found in between tall 

 scrub on protected mountain sides at 8000 feet elevation. 

 Bears burrs like those of a chestnut, which contain chin- 

 quapin-like nuts; it bears, however, also catkins like a 

 hazel or an alder when It is leafless. Leaves somewhat 

 like those of a chestnut but of a thinner and less per- 

 sistent structure. Of value possibly as a new nut-bearing 

 tree, fit for regions where the winters are not too se- 

 vere." (Frank N. Meyer's Introduction and description.) 



Citrus sp. (Rutaceae.) 39897. Cuttings from near Lian 

 dja pa, Kansu, China. "A peculiar species of citrus grow- 

 ing into a large tree, bearing loose-skinned, round, flat- 

 tened fruits the size of mandarin oranges. Color of rind 

 light-yellow; rind full of oil-glands, smelling like a fine 

 lemon; segments separating easily; fairly juicy and of an 

 agreeable sharp sour taste; contains plenty of large seeds. 

 These sour mandarin fruits make a very pleasing lemonade 

 cut up with rind and all in a tumbler of water and some 

 sugar added. They also taste well when cut up in slices 

 in hot tea, while a few pieces of rind added to a soup or 

 stew gives a novel and agreeable flavor. The trees are of 

 thrifty growth, making large heads of dark-green foliage, 

 they are prolific bearers, apparently; young shoots armed 

 with large spines. They are not grafted or budded but 

 propagated from seeds only. This citrus is found at ele- 

 vations from 2000 to 4500 feet, and where they grow one 

 finds the following trees cultivated: Diospyros kaki, Ficus 

 carica, Punica granatum, Juglans regia-, Pyrus sinensis, Morus 

 alba, Hovenia dulcis, Ligustrum lucidinn, Chamaerops excelsa and 

 Phyllostachys sp. Of value possibly as a tree for the home 

 garden in sections north of the citrus belt proper." (Frank 

 N. Meyer's introduction and description.) 



Corylus ferox tibetica (Bat . )Franch. (Fagaceae . )39907. Cut- 

 tings of a hazel from near Pao dji, Kansu, China. "A ha- 

 zelnut growing into a tree from 80 to 100 feet tall, having 

 a trunk often a few feet in diameter. Bark reddish brown 

 and peeling off in loose layers, like that of a birch.
