66 POPULAR FIELD BOTANY. 
SYNGENESIA. SUPERFLUA. 
CoROLLIFLORA, ASTERACES. 
SENECIO. (GrovunpsE£t.) 
Generic Character. Jnvolucre cylindrical; the scales of which 
it is formed, narrow, equal, with several smaller ones at the base, 
their tips often brown. JVowers either flat or with rays. Recep- 
tacle naked. 
SENECIO vULGARIS. Common Grounsel. This well- 
known plant need not be described very fully, as this work 
is not intended to supersede more learned botanical works, 
but merely to point out those species easily met with by the 
young student. As every one knows this plant, I shall only 
mention that it is im flower from February to November, 
but is occasionally found through the winter, when a 
favourite bird may have its cage made gay by its green 
leaves. The specific distinctions are, leaves clasping the 
stem, divided and toothed, flowers in clustered heads, desti- 
tute of a ray. There are eight species, but the Senecio 
vulgaris is alone found early.
