xlvi. composite: CORTMBIFERJE. [ Achillea . 
46. Achillea Linn. Yarrow. Milfoil. 
Pappus 0. Receptacle flat, chaffy. Involucre ovate, imbri- 
cated. Florets of the ray 5 — 10, roundish or obcordate. — 
So named because its healing virtues were said to be first dis- 
covered by Achilles. 
1. A. Ptarmica L. ( Sneeze-wort ) ; leaves shining glabrous 
linear-lanceolate acuminate uniformly and sharply serrate, 
serratures adpressed scabrous at the margin, ray 8 — 12- 
flowered. E. B. t. 757. 
Moist meadows and pastures, especially in mountainous districts, 
If.. 7, 8. — Stem 1 — 3 feet high, erect, terminating in a rather large 
corymb, the disk as well as ray of whose flowers is white. Leaves 
sometimes slightly dotted. — When dried and pulverized the plant 
has been employed to excite sneezing. 
2. A. *(lecolurans Schrad. ( dotted-leaved Y.) ; leaves downy 
closely dotted linear-lanceolate coarsely and doubly serrate 
pectinate at the base, serratures spreading, segments at the 
base radiating, ray 5 — 6-fiowered. A. serrata Sm. (not Retz .): 
E. B. t. 2531. 
Near Matlock, Derbyshire. 1L. 9. — Commonly cultivated in 
gardens under the name of A. alpina, to which, as well as to A. ser- 
rata, it appears to approach very closely ; the native country of all the 
three would seem to be Siberia, if indeed some be not mere garden 
productions. Ligules buff-coloured. 
3. A *tnnacetif6lia All.? (Tansey -leaned Y.) ; leaves bipin- 
natifid with a broadly winged serrate midrib, segments broad 
and teeth of the midrib inciso-serrate. 
Ringing Low, near Sheffield; Cromford Moor, Derbyshire. 11. 
7. — We have seen no British specimens, and do not know what 
species is meant ; the above character is therefore abridged from Mr. 
Babington’s manual, who adds that the root-leaves have a lanceolate, 
the stem ones an oblong outline, usually bipinnatifid, but sometimes 
only once pinnatifid ; rachis with large inciso-serrate teeth especially 
just under the pinnae. It is probable that the above is A. dentifera 
DC., or A. tnagna All. ; the true A. tanacelifolia is said by De Candolle 
to have an entire rachis. The allied species are so much cultivated 
in gardens, that, we doubt of this and the last being truly indigenous. 
4. A. Millefolium L. ( common Y. or M.) ; leaves deeply bi- 
pinnatifid, lobes incise, segments linear acute, stems furrowed, 
scales of the involucre nearly glabrous. E. B. t. 758. 
Pastures and way-sides, frequent. If.. 6 — 9. — Heads of flowers 
small, white, or sometimes rose-coloured. Leaves woolly or nearly 
glabrous. The quality of this plant is highly astringent, and the 
Highlanders are said to make an ointment of it, which dries and heals 
wounds.
