"bristles between the florets. Kay-florets neuter. Achenes 

 hairy ; pappus of few membranous pointed scales. There are 

 about six species. Named in honour of a French botanist. 



1. G. aristata. A perennial about 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. pi eta. 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. 

 tricolor is a semi-double 



variety, having the rays purple at the base, white in the middle, 

 and yellow at the tips. The familiar bwolor 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 ; coronata, brown and orange-red. 



Hymenoxis Ccdifornica is a slender branching annual with 

 glabrous pinnatifid leaves and yellow flower-heads on long 

 slender peduncles. Eeceptacle paleaceous, glandular. Pappus 

 chaffy. 



The genus Helenium is composed of a few tall perennial 

 species, natives of North America. Receptacle chaffy, between
