. Queensland. Gilbert river, F. Mueller. 
or almost hair-like teeth, from under 4 in. to about 3 in. long. ower- 
heads solitary, terminating the rather numerous leafy branches. Involucre 
broadly hemispherical, about 3 lines diameter, the bracts narrow, acumi- 
nate, nearly equal, in 2 or 3 rows. Ray-florets numerous and narrow, bu 
the ligule at least 2 lines long, the disk-florets very numerous. Achenes flat 
and obovate, as in the rest of the genus, but the pappus-bristles not nume- 
tous, exceedingly fragile and deciduous and strongly barbellate. 
Victoria. Port Phillip, F. Mueller—A very distinct plant, of doubtful affinity, with 
something of the habit of a Mizwria, but more branched, and, notwithstanding the diffe- 
tence of the pappus, which is nearly that of Gymnostephium, appears to be best placed in 
; ` ave thought, indeed, that it might have been some Cape ymnostephium, 
ied to G. gracile, and accidentally introduced, but the disk-florets are certainly fertile, 
and the involucre and rays are those of Erigeron, and not of Gymnostephium 
4. E. canadensis, Linn.; DC. Prod. v. 289. An erect not much 
branehed annual, of 1 to 3 ft., glabrous or hispid with short spreading hairs. 
Leaves linear, 1 to 3 in. long, entire or rarel with a few distant teeth. 
Flower-heads small and very numerous in a large oblong or rarely corymbose 
lerminal panicle, the peduncles very slender. Involucre ovoid, nearly gla- 
brous, the bracts narrow, acute, about 2 lines long. Ray-florets very nume- 
tous, slender, but ligulate, scarcely exceeding the involucre, white; disk- 
rets not so many. ; 
Port Jackson, JFoolls, probably introduced. The species, of American 
N.S. Wales. 
origin, is now common as a roadside weed in most tropical countries, as well as in a great 
part of Europe. 
- Sgotion II. Canorus.—Inner rows of the female florets or nearly all fili- 
form, shorter than the style and not expanded into a ligula. 
5. E. conyzoides, F. Muell. in Trans. Phil. Soc. Vict.i. 105; in Hook. 
Kew Journ, vi 146; aud Fragm. v. 81. An erect annual, of 14 to CES 
more corymbosely branched than Æ. linifolius, and quite glabrous. Stem 
leaves linear or lanceolate, often 2 to 3 in. long, quite entire, the radical and 
lower leaves longer and broader, entire or remotely toothed, narrowed into a 
long petiole. Flower-heads larger than in E. linifolius, forming a terminal 
t 
ceedingly numerous, the outer 1 or 2 rows ligulate, but so na as to - 
CORR filiform, exceeding the pappus, the 1 tubular, anc 
Ee disk-florets very few. Style-appendages short.
