Composite— A retotis. 263 
large, terminal, disk brown, ray orange, closed in dull weather. 
A. acatlis and widuldta are referred hither as varieties, 
differing only in the shades of yellow in the ray-florets. 
Venidium calendulacewm 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. Ray- 
florets neuter, disk-florets perfect. Achenes hairy, with a 
double pappus of finely-toothed scales. The name is an ampli- 
fication of yafa, richness. 
1. G. spléndens.—-This 
trailing perennial plant 
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 
bandsome 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 splén- 
dens, and the latter has smaller pale yellow flowers.
