undivided. Heads rather large. Florets dingy yellow, the marginal 
pistillate ones very short. — Aromatic and bitter, much used in 
medicine. 
**** Heads homogamous ( all the florets perfect and fertile'). Receptacle 
glabrous. Seriphida. 
4. A. mcirUima L. (Sea IF.) ; leaves downy, radical and 
lower cauline ones bipinnate, upper often pinnate or pinnatifid, 
segments linear, heads racemed oblong 3 — 5-fiowered. — a. ra- 
cemes drooping. E. B. t. 1706. — 13. racemes erect. E. B. 
t. 1001. A. Gallica Willd. 
Sea-shores and in salt marshes. Rare in Scotland. If.. 8, 9 
What we consider the two varieties may he seen growing together, 
and sometimes from the same root ; but De Candolle attributes to a. 
an involucre with constantly 5 florets, the inner scales obtuse ; and to 
j8. always 3 florets, with the inner involucral scales acute. A. salina. 
Willd. appears to be intermediate. 
5. A. * ccerulescens L. ( bluish M.) ; leaves hoary most of them 
lanceolate undivided tapering at the base, lower ones variously 
lobed, heads 3-flowered oblong cylindrical spicate, scales of 
the involucre hoary subcarinate. E. B. t. 2426. 
Sea-coast near Boston, Lincolnshire, and at Portsmouth. 7f . 8, 9. 
— No such plant has been found in these localities for many years, 
and there seems to be no doubt of the allied A. maritima having been 
mistaken for it. (See Dr. Bromfield in the Phytol. iii. p. 491.) 
It is peculiarly a Mediterranean species. 
** Pappus pilose. (Gen. 28 — 33.) 
28. Eupatorium Linn. Hemp-agrimony. 
Aclienes angled or striate. Pappus pilose and rough. Re- 
ceptacle naked. Involucre imbricated. Styles much exserted, 
with long blunt papillose branches. Florets all perfect (never 
yellow). — Named from Eupator, the surname of Mithridates, 
king of Pontus, who is said to have brought this plant into use. 
1. E. cannubinum L. ( common II.); leaves downy opposite 
subpetiolate 3 — 5-partite, their segments lanceolate deeply ser- 
rate, the middle one the longest, heads 5 — 6-flowered, scales 
of the involucre about 10, 5 outer ones short obtuse. E. B. 
U 428. 
Banks of rivers and watery places. 7f. 7 — 9. — Stems 3 — 4 ft. 
high branched. Heads of flowers very numerous, pale, reddish-purple, 
thickly crowded in terminal corymbs. — Plant slightly aromatic. 
29. Linosyris Cass. Goldylocks.
