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- 

 cultural Journal of the Union of South Africa, April,

Barosma 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 

 If 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. betuli'ia. (Adapted from The Agricultural Journal of 

 the Union of South Africa, April, 1893.) 



Brassica besseri'.in:'. (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, Hojaria, 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.)
