SYNGENESIA. SUPERFLUA. 
CoROLLIFLOR2. ASTERACEE. 
PULICARIA. (FLEA-BANE.) 
Generic Character. Jnvolucre hemispherical, closely covered 
with narrow scales. Pappus double. lowers yellow. 
PULICARIA DYSENTERICA. (Plate XIX. Fig. 74.) Com- 
mon Elea-bane. his genus is distinguished from Erigeron, 
by both rays and centre being yellow; but whether this 
derives its English name from the property of driving away 
fleas also, I do not know. ‘This species is common in 
watery places, and its soft, downy leaves and flowers make 
it very pretty. It grows about a foot high, with many 
long, narrow leaves clasping the stem, and heart or arrow- 
shaped at that part, both stem and leaves very woolly. 
Flowers in small bunches, yellow, and with the ray longer 
than the centre part. This distinguishes it from 
Puricarta vuLearts, Small Mlea-bane, which has the ray 
scarcely longer than the centre. The leaves are long, half 
clasping the stem, and narrow at the base. The stem 
branched and hairy. It is found in moist sandy places 
where water has stood.
