PYRETHRUMS 
Natural Order Composirm. Genus Pyrethrwm 
PYRETHRUM (from the classical Greek name for the plants, Pyrethron). 
A genus united with Chrysanthemum by most authors, and under which 
genus we have already described several species formerly considered as 
Pyrethrums. We have retained the distinction here because there is 
now a considerable number of florists’ varieties known as “Double 
Pyrethrums,” and to group them under Chrysanthemums is calculated to 
cause much confusion. The chief characters by which Pyrethrum is 
distinguished from Chrysanthemum consist in the fruits being without 
wings, and the possession of a pappus, which, however, takes the form 
of a mere membranous border, raised above the fruit and sometimes 
indented all round (see Plate 151, Fig. 1). 
The popular bedding plant known as Golden Pyrethrum, Fever- 
few, or Golden Feather is described under Chrysanthemum prealtum. 
The only species we propose to treat separately is— 
eesti PYRETHRUM ROSEUM (rosy). A perennial with stems 
: 2 feet high, well clothed with pinnately-lobed leaves, 
Which are again deeply cut, much resembling those of Milfoil, and of a 
bright green. The flower-heads are a couple of inches across, with yellow 
disk ; the ray-florets rose-coloured ; May and June. Introduced from 
the Caucasus (1804). The flower-heads are said to form a principal
