of lanceolate obtuse scales, membranous on the margin. Florets nu- 
merous, those of the ray with a long ligulate lip, two or three toothed 
at the end, blue, spreading, those of the disk short, tubular, yellow, 
the limb five-cleft. Fruit oblong, compressed, downy. Pappus of 
rough spreading bristle hairs. 
Habitat.—Salt marshes; frequent. 
Perennial ; flowering in August and September. 
The species of this genus are very numerous (De Candolle enu- 
merates one hundred and fifty). They are commonly known by the 
names of Michaelmas Daisy, Christmas Daisy, China Aster, &c. 
Some of them are very ornamental, and flower at that season of the 
year, when there are but few others to rival them. As an autumnal 
border flower, few surpass in beauty or variety of colour the flowers 
of the China Aster, which are single, semi-double, and double. They 
are easy of cultivation: the best method is by first raising them in a 
hot-bed of moderate heat, and transplanting them into the open 
borders in the latter end of April or May: they require a good 
loose soil and an open sunny exposure,
