Citrus sp. (Rutaceae), 50967. From Swatow, Kwang- 
tung, China. Seeds presented by Mr. A. H. Page . "A fruit 
we call the Chinese lime. The nearly ripe one weighs 
now about 4| ounces, the green one 2 ounces. Either 
would make a fairly good 'lemon' pie, the riper one 
having the better flavor. The tree is very hardy and 
bears immense crops. I picked nearly 600 last fall 
from a tree about 9 feet high and of moderate spread. 
I certainly believe it Is worth a trial for lime juice 
and citric acid." (Page.) 
Coffea encelsa (Rublaceae), 50632. Coffee. From Cape 
Town, Cape Colony. Seeds presented by Mr. J. Burtt- 
Davy, through Mr. George H. Murphy, American consul 
genera]. A large-leaved tree of vigorous growth, closely 
allied to Coffea liberiea, but a stronger grower, and ap- 
parently a better producer; the seeds are, however, 
smaller than those of the true Liberlan coffee. It is 
apparently a plant which has considerable powers of 
thriving under very adverse condl tlons . Nearly 9 pounds 
of berries to a tree have been gathered from this va- 
riety. It prefers low situations but may be planted 
up to 2,000 feet above sea level. 
Below is a table showing, the weight of berries 
of various coffees required to give one kilogram of 
marketable coffee: . > ? 
Coffea eanephora var; ianuimengU 4.7 kg. 
eanephora 3.8 kg. 
robmta (Java) 3.8 kg. 
exeelsa 5.5 kg. 
liberiea 12.0 kg. 
dewevrei 8.3 kg. 
aruwimiensis 6.7 kg. 
C. exeelsa Is found in the wild state In central 
Africa at altitudes of 2,200 feet in a climate which 
Is dry for six months of the year and has a rainfall 
of at least 40 Inches during the remaining six months. 
The temperature In summer is tropical ..while in De- 
cember and January It falls below 10° C. (50° F. ) at 
night. This type does well in equatorial regions, has 
a satisfactory strength in caffein, and, though somewhat 
bitter, it has an excellent flavor. In Tonking its 
growth has been remarkable and entirely free from in- 
sect and fungous pests. The bean is small and uniform 
in size and it is hoped that it may sell in competition 
with Arabian coffee blended with Mocha. In appearance
