 Good Hope, where it was collected 



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 Tigridia 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 

 Gazaxta rtgens 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. 

 Knights 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 ; partly brown, as \\\ paronia.

. 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 

 supply of water. Easily multiplied by dividing the root- 

 stock.
