oil deposits a solid barosma camphor which, when 
purified, has the odor of peppermint. The leaves con- 
tain the most oil in January or February but it is 
better to clip the twigs in early March, after most of 
the seeds have fallen. In clipping, care is taken to 
leave a sufficient number of buds for the next year's 
growth. Leaves of one year's growth are far superior 
to those two years old. They are astringent and con- 
tain a bitter substance which acts beneficially on 
the stomach. The Hottentots and Bushmen used a solution 
of the leaves for bladder and kidney complaints, and 
the roots for snake bites. (Adapted from The Agri-

Eanisma crenulata (Rutaceae), 47954. From Burttholm, 
Vereeniging, Transvaal, South Africa. Seeds presented 
by Mr. J. Burtt-Davy. The large-leaved buchu, - the 
kind most esteemed in the colony, although not the 
highest priced in London, - is often distinguished as 
the "true buchu." It is a twiggy shrub, 3 to 4 feet 
high with smooth purplish branchlets, and leaves 1 to 
1| inches long. The pale purplish flowers, produced 
in October and November, are very plentiful and last 
for a long time. The uses are the same as those of 
B. betulina. (Adapted from The Agricultural Journal of 
the Union of South Africa, April, 1893.) 
Brassica besseriana (Brassicaceae ) , 47928. Mustard. From 
Aden, Arabia. Presented by Mr. Addison E. Southard, 
American consul. "Two kinds of mustard are grown in 
the Yaffai Dthala districts of the Aden hinterland; 
and in the Arabian Red Sea districts of Dubham, Shargah, 
Koraisha, Hojarla, and other places. These two kinds 
are known in Arabic as khardal (or ghardal) and tartar. 
The first-named variety yields but little oil while 
the latter yields proportionately a good deal of oil. 
The clerk in this consulate has been sent to canvass 
the Arab families in Aden and Sheikh Othman with whom 
he has acquaintance, and has succeeded in obtaining 
from the medicine chest of one old gentleman a few 
grams of the khardal (or ghardal) variety which are here- 
with enclosed." (Southard.) 
Baeklandia populnea (Hamamelidaceae ) , 47649. From
