Composite A rctotis. 263 



large, terminal, dfek brown, ray orange, closed in dull weather. 

 A. acaulis and undulata are referred hither as varieties, 

 differing only in the shades of yellow in the ray-florets. 



Venidium calendulaceum is an allied Cape annual, growing 

 in dense dwarf tufts. Leaves large, obovate, lyrate, pube- 

 scent. Flower-heads terminal, similar to those of the Mari- 

 gold. It differs from the last genus in the absence of, or, if 

 present, minute pappus. 



39. GAZANIA. 



Another South African genus of showy-flowered herbs, pos- 

 sessing the same peculiarity of opening in bright weather 

 only. Involucral bracts cohering to nearly the summit. Kay- 

 florets neuter, disk-florets perfect. Achenes hairy, with a 

 double pappus of finely-toothed scales. The name is an ampli- 

 fication of 7aa, richness. 



1. G. splendens. This 

 t railing perenni al p 1 a 11 t 

 is much, in vogue for 

 bedding, and produces 

 a very brilliant effect in 

 sunny weather. Leaves 

 linear, spathulate, silky, 

 white below. Flower-heads 

 large, ray bright orange 

 with a black and white spot 

 at the base of each floret, 

 disk of a paler yellow. It 

 is believed to be of hybrid 

 origin. 



G. Pavonia has pinna- 

 tifid hairy leaves and large 

 handsome flower-heads with 

 broad ray-florets in which 

 the spot at the base is 

 brown with a white central 

 dot and a tinge of green. 

 G. rigens and G. uniflora 

 are two of the original 

 species from which the 



garden varieties have been raised. The former is near splen- 

 dens, and the latter has smaller pale yellow flowers.
