GENUS II. 
DIPLOPAPPUS, Cass. THE DIPLOPAPPUS. 
Lin. Si/st. SYNGENESIA POLYGAMIA SUPERFLUA. 
Generic Chiracter. — The ray flowers in one series, feminine. Disk hermaphrodite. Pappus in two series. Corollas of the disk flowers 
regular. Acfaeninm rough. 
Description, &c. — This genus has been separated from the genus Aster, on account of the pappus being in 
two rows ; and hence the name, which signifies Double-pappus. Most of the species are greenhouse shrubs.

Engrayings. — Bot. Reg. t. 1693 ; and oar ^^. 6, in Plate 4.3. I cously hairy, somewhat stem-clasping. Stem cofymbose; bravebes 
SpKcinc Character. — Suffruticose. Leaves linear, obtuse, glau- | one-flowered. Involucre squarrose.

Californians, it requires a dry, open situation, and is killed by much wet. It was at first supposed tender, but it 
is now found to be more injured by wet than frost. 
GENUS in. 
ERIGERON, Willd. THE FLEABANE. 
Lin. Syst. SYNGENESIA SUPERFLUA. 
Generic Character. — Involucre imbricated. Receptacle naked. Florets of the ray very narrow. Pappus hairy ; hairs rough. 
Description, &c. — This genus contains several British plants which, under the name of Fleabane, are well 
known to persons residing in the country ; and which were formerly in much repute, as their smell, when dried, 
was supposed to drive away fleas, and other noxious insects. The British species have no beauty to recommend 
them ; but some of the American species are well deserving of cultivation. The generic name of Erigeron is said 
to be derived from the Greek, and to signify To-grow-old-soon ; but this name does not appear very applicable, 
as some of the flowers are remarkable for the long time they continue in perfection.
