Composite—Liatris. ‘231 
flowers. Itis a member of a large genus, remarkable in having 
almost constantly four florets in each head. Nardésmia fra- 
grans, Winter Heliotrope, is very near our native Butterbur, 
Petasites vulgaris, but it has fragrant flowers. 
Eupatérium cannabinum, Hemp Agrimony, is one of the 
tallest and handsomest native plants belonging to this order. 
It has hairy pinnate or 3-foliolate leaves and pale purple flowers 
in terminal corymbs, from July to September. Two or three 
Mexican species of this genus have been recently introduced, 
and may prove valuable for bedding purposes, 
4, LIATRIS. 
A North American genus of handsome perennials resembling 
the Cynaree in habit. Involucral bracts small, numerous, im- 
bricated, in many series. Receptacle naked. Pappus feathery. 
The name is unexplained. 
1. L. scariésa.—About 2 feet high. Leaves very long and 
narrow. Involucral bracts purple-margined ; flower-heads 2 
inches in diameter, purple, in an elongated corymb.  Sep- 
tember. 
2. L. spicata.—This grows from 1 to 2 feet high. Stems 
leafy. Leaves lanceolate, ciliate. Flower-heads sessile, in a 
long spike, purple. One of the most desirable species, flowering 
in July, and onwards for a considerable period. 
L. odoratissima and élegans are both purple-flowered, the 
former sweet-scented, 
Trig III.—ASTEROIDE, 
Leaves usually alternate. Outer or ray-florets often ligulate, 
female ; disk-florets bisexual. Branches of the style linear, flat, 
often downy. : 
5, ASTER. 
A genus of about 200 species, chiefly from North America. 
The majority are perennials, often tall and leafy, having the 
flower-heads arranged in racemes or panicles. Involucral 
bracts multiseriate. Ray-florets uniseriate, female. Pappus 
of numerous unequal hispid bristles. Our native Michaelmas 
Daisy, A. Tripdliwm, is agood example. ’Actip is the Greek 
for star, hence the English name Star-flower. The following is 
a selection of some of the most desirable species.
