bristles between the florets. Ray-florets neuter. Achenes 
hairy; pappus of few membranous pointed scales. There are 
about six species. Named in honour of a French botanist. 
1. G. aristatu.—A perennial ubout 18 inches high. Leaves 
lanceolate, entire, or remotely toothed. Flower-heads about 2 
inches across, normally yellow, with prominent exserted reddish 
styles in the rather large disk. But it has given birth to 
several varieties far sur- 
passing the original in 
brilliancy of colouring, 
as, for example, grandi- 
flora (fig. 137), with a 
dark brown disk and the 
lower part of the ray 
crimson shading off into 
orange and_ bordered 
with yellow. Some of 
these varieties have pro- 
bably arisen from crosses 
between this and the fol- 
lowing species. 
2. G. Drummondii, 
syn. pictu.— Also per- 
ennial, with rather larger 
leaves coarsely and 
sparsely toothed or lobed. 
Flower-heads crimson 
and yellow, larger than 
in the preceding. G. D. Fig. 187. Gaillardia aristata, var. grandiflora, 
tricolor is a semi-double ene BES) 
variety, having the rays purple at the base, white in the middle, 
and yellow at the tips. The familiar bicolor is referred to this 
species. Perhaps these and the preceding should be included 
under one species. 
There are some other species: as, Richardsoni, brown disk 
and yellow ray ; corondta, brown and orange-red. 
Hymenéais Califérnica is a slender branching annual with 
glabrous pinnatifid leaves and yellow flower-heads on long 
slender peduncles. Receptacle paleaceous, glandular. Pappus 
chaffy. 
The genus Heléniwm is composed of a few tall perennial 
species, natives of North America. Receptacle chaffy, between
