which it retains and falls off with; circiimstances that do 
not belong to Gazania. 
The subject of the present article is from the Cape of 
Good Hope, where it was collected by Mr. Niven, for 
Mr. Hibbert’s late botanic establishment at Clapham, 
about the year 1804. ‘The specific name seems to have 
been suggested by some resemblance in the colour of the 
ray to that of the corolla of the Ticrrpra pavonia: The. 
coriaceously thickened calyx is formed of a concretion of 
numerous unequal leaflets, the inner ones of which remain 
separated near the top, into about 4 imbricate series. The 
dark irregular marks and small one-bristled knobs or tu- 
bercles, that are seen on its outside, denote the termina- 
tions of the several leaflets that are merged in its substance. 
When the flower closes in the evening, or from the absence 
of sunshine, besides the general movement by which the 
ray converges, each of its broad semiflorets rolls itself up 
very compactly from each side, inwards, to the middle; to 
expand again in the morning, or when the sun appears. In. 
Gazania rigens the circle that encompasses the foot of the 
ray is black, here of an hazel-brown on the inside, and blue 
on the opposite surface. At Messrs. Colville’s and Mr. 
Knight's nurseries, we have seen a plant which we take to 
be an hybrid, or cross production of the two, partaking in 
almost equal proportions of those parts in which the pa- 
rents differ, but altogether smoother and more robust than 
either; the very circle of the ray is partly black, as in 
rigens ; pattly brown, as in pavonia. 
The present drawing was made in part at the Comtesse 
de Vandes’ botanic-garden, and in part at Messrs. Fraser’s,. 
in Sloane Square. 
The species is certainly perennial, although marked in 
the Hortus Kewensis as biennial. Should be kept in the 
greenhouse, where it requires no care beyond an occasional 
SupDly of water. Easily multiplied by dividing the root- 
stock.
