572 oN THE NATURALIZED WEEDS OF BRITISH KAFFRARIA. 
on the other, on long petioles, entire, ovate, subcordate at the 
base; base unequal. Flowers on short pedicels in the forks of 
the branches, erect, solitary ; calyx 4 inches long, inflated, bilobed; . 
corolla longer than the calyx, 5-plaited, -angled, and -pointed, 
pure white, sweet-scented. Stamens distinct; anthers. not co- 
herent round the style. Flowers from December to February, 
opening only in the evening or in cloudy weather, and is common 
in gardens. 
The Chenopodium which I have left unnamed grows in the 
greatest profusion in every waste place about King William’s 
Town. Its odour is exactly that of chloride of lime. It is a 
woody much-branched perennial with a leaf like that of C. Botrys, 
Linn. Iam quite unable to discover its name. The native C. 
Caroxylon, Thbg., comes up in immense quantities on the sites of 
old Kaffir kraals and gives forth a most offensive odour. "There 
are several weeds not mentioned in my list which are common in 
the western distriets of the Cape Colony and about Graham's 
Town, but which I did not observe in Kaffraria; and I do not 
think they have yet penetrated there. These are Capsella Bursa- 
pastoris, Erodiwm moschatum, and Oxalis corniculata. 
The Prickly Pear (Opuntia vulgaris, Mill.) was introduced 
during the Kaffir war of 1836 into Kaffraria as a means of defence 
against the natives ; and it grows very freely, having become almost 
naturalized about old military posts. It is not so abundant as 
supposed, however; for many persons confound it with the tall 
prickly Euphorbias so characteristic of the Kaffrarian flora. 
Amongst native plants which are met with about gardens as 
weeds I may mention Lepidium myriocarpon and a species of Aizoon. 
A Plantago is common by roadsides and in waste places, but I 
do not know to what species it should be assigned. 
Two species of Commelyna, the one with bright blue and the 
other with buff-coloured flowers, are complete weeds in damp 
places about houses and military posts. They are, I suppose, na- 
tive species. 
The Common Watercress has been introduced into the water- 
course which supplies the garrison with water at King William’s 
Town, and is fairly established there. 
. Should these imperfect notes prove of any service to you, I shall 
feel flattered by your making any use you please of them. 
Believe me, my dear Dr. Hooker, 
Very truly yours,
