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." (Prank 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 Tcaki, Ficus 
carica, Punica granatum, Juglans regia, Pyrus sinensis, Moms 
alba, Movenia dulcis , Ligustrum lucidum, 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.)
