258 XL vi. composite: corymbifervE. \_ Anihemis . 
Flowers large, upon long naked peduncles. Dish very convex : ray 
large. Plant slightly aromatic. Achenes with 3 prominent thick smooth 
ribs and more or less rugose intermediate spaces ; of these last the 
two internal ones are narrow, the external one broad and marked at 
the apex with an imperfect smooth rib, on each side of which there 
is a roundish smooth glandular depression. In the ear. /3. the ribs 
are broader than in var a., and consequently all the intervening 
spaces and the glandular depressions are narrower ; but they seem to 
vary in this respect in the same head. 
3. M. Chamomilla L. ( common IF.); leaves glabrous bipinnatifid 
the segments capillary, involucre nearly plane its scales linear 
obtuse, receptacle cylindrical-oblong hollow. E. B. t. 1232. 
Corn-fields and waste ground, in various places. 0. 6 — 8. — 
Stem about 1 foot high, erect and branched. Heads of flowers with a 
conical dish ; the ray very obtuse, truncate and toothed. Receptacle 
narrow, much elevated, twice as long as broad, and often acute. 
Scales of the involucre scarcely so membranaceous at the margin as 
in the preceding species. This has a bitter taste, and a faint but 
aromatic smell, not unlike that of the common or true Chamomile 
( Anthernis nobilis). 
45. A'nthemis Linn. Chamomile. 
Achenes terete or obscurely 4-angled. Pappus a membra- 
naceous border or 0. Receptacle convex, chaffy. Involucre 
hemispherical or nearly plane, the scales imbricated, mem- 
branaceous at their margins. Florets of the disk terete, of 
the ray oblong-linear. — Name: avOtyir, a Jlower ; from the 
profusion of its blossoms. 
* Florets of the ray with a style. 
f Scales of the receptacle thin, membranous, obtuse. 
1. A. nobilis L. ( common C.) ; leaves bipinnate segments 
linear-subulate a little downy, receptacle conical its scales 
scarcely longer than the disk. E. B. t. 980. 
Dry gravelly pastures and waste places, in several parts of England. 
Isles of Islay, Cumbrae, and Bute, Scotland. Kerry, Ireland. 21.7 — 9. 
— Stem about a foot long, procumbent and much branched; each 
branch terminated by a single flower, whose disk is yellow, at length 
conical, and ray white. The whole plant is intensely bitter, highly 
aromaiic and much used medicinally. Its principal virtues are sup- 
posed to reside in the involucre, which contains an essential oil. 
j j Scales of the receptacle with an acute rigid point. 
2. A. *A'nglica Spr. (Sea C.) ; leaves pinnatifid somewhat 
hairy, lobes inciso-serrate acute bristle-pointed rather fleshy, 
“ receptacle flat, its scales subulate shorter than the opened 
florets, achenes crowned with a very narrow entire border.”
