it is apparently made up of a large number of densely 
crowded sections, quite distinct from each other, but 
radiating from a small central stone or hard seed. On 
this specimen the fruit was red , but there are varieties 
with fruit of different colors. A white-fruited kind, 
havire comparatively large fruit , is said to be of very 
excellent quality. The tree Is commonly propagated 
by seed, but the Japanese assert that It can also be 
grafted on the mulberry. It is planted by them partly 
for fruit and partly for ornament. The bark is an 
important dye-stuff." (C. C. Georgeson. )

Parimri mobola (Rosaceae), * 48469-71. From Johan- 
nesburg, Transvaal. Seeds collected by Mr. J. Burtt- 
Davy. "Mobola plum, from Choma, North Rhodesia."

Nocha or Noxa. One of the most handsome and use- 
ful trees of all the Hullla district; forming exten- 
sive forests in the mountainous parts of Morro de Lo- 
pollo. It rises to a height of from 15 to 40 feet 
with a maximum diameter of 4 feet; the trunk branches 
dichotomously and tortuously. The crown is dilated 
and the dense, leathery evergreen foliage, deep green 
above and snowy white beneath, is of extraordinary 
effect. The wood is generally employed in Huilla for 
the manufacture of furniture and other domestic arti- 
cles and, when properly seasoned, makes good lumber. 
But wbat is most advantageous in this tree is its fruit, 
since at the time of its ripening a large proportion 
of the native population is sustained almost exclu- 
sively on Noxas. So great is the abundance of these 
fruits in the neighborhood ofLopollo and Humpata that 
the natives offer large baskets of them to the Euro- 
pean colonists at the price of about 'ten cents' for 
a hundred fruits. The fruits are the size of a small 
peach, containing the bulky stone enveloped in a fari- 
naceous-pulpy mass, sweet, and of a very agreeable 
aroma. (Adapted from Hiern, A Catalogue of Welwitsch's
