as the types of those species, for it at once becomes perfectly 
obvious from the characteristics of habit and branching that his 
description of U. capensis so perfectly coincides with the specimen 
marked “ Urtica capensis [3,” and with no other, that it was certainly 
made from that specimen, and that neither of the sheets marked 
“a” were taken into account at all, erefore the specimen 
marked “ Urtica capensis 3” must be taken as the type of that 
species. 
Likewise with Urtica caffra, only the specimen marked “ Urtica 
caffra 3” agrees with his description of that species, and it does so 
most accurately, especially as to the particulars he gives relating to 
the stem and branches, and must therefore be accepted as tt e type 
of Urtiea caffra, Thunb., whilst the specimen on sheet “a,” b 
its prostrate rooting stems and opposite leaves, is so distinctly 
opposed to Thunberg" s enema of U. caffra, that he cannot have 
used it for that descriptio 
The bisexual sia Soa of Droguetia Thunbergii on dissection 
are puzzling, owing to the manner in which the perianths of the 
ale flowers seem to cling to the inner side of the involucre ; they 
ao not seem to be adnate to it, but appear to be held there by 
the wool, and it is difficult to separate them. When one had been 
- freed, the mystery was explained by finding that the outside of the 
perianth of the male flowers was beset with minute hooked hairs, 
which are entangled in the wool on the inside of the perianth and 
so prevent separation.

J. M. HILuier, 
The following notes on Vegetable Economic Products were com- 
piled during a recent visit made for the purpose of mgrvechisen 
certain oie of irregular import into this country. 
records on the same subject have appeared in Kew Bulletin, 1907, 
p. 61, eg 1908, p. 183. 
TIMBERS. seckn the docks large quantities of timber were to be 
seen, including the following :— 
From West African ports mahogany of various dimensions, both 
in the round with or without the bark on, and in 
Much of this timber is transhipped ns the United States of America. 
Of particular interest was a parcel of African oak Bk ao alata) 
from the Cameroons. Mr. s A. Weale, a 
timber merchant, kindly tarnished me with the following particulars 
of this timber. “ Owing to its great weight and the difficulties of 
shipment obtaining on the African Coast, this timber although well 
own in certain circles has not up to the present found the demand 
which its virtues deserve. Only isolated logs have come to this 
market and these from the Gol oast where it is known as 
‘Karkoo.’ It is there the favourite wood ae railway sleepers and 
heavy constructional work generally. It is now being imported from 
Duala in the Cameroons, and the first shipenénts just to hand mark 
an epoch in the West African trade. This is the first import that
