GENUS XXXVII. 
SERRATULA, Dec. THE SAW-WORT. 
Lin. Syst. SYNGENESIA POLYGAMIA ^QUALIS. 
Generic Character. — Involucre imbricate, scales unarmed. Receptacles bristly or chaffy. Pappus hairy, persistent. Hairs rigid, unequal. 
Description, &c. — The plants belonging to this genus all bear considerable resemblance to the thistle, but 
they are easily distinguished by the scales of the involucre not being spiny. The genus takes its name from the 
leaves being supposed to bear some resemblance to a saw, but the resemblance is not very striking. Only a few 
of the species are ornamental. 
1.— SERRATULA QUINQUEFOLIA, Dec. THE FIVE-LEAVED SERRATULA. 
Engraving. — Bot. Mag. 1871. 
Specific Character. — Leaves serrated, impari-pinnate ; peduncles one-flowered. Scales of the involucre elongated, and coloured. 
Description, &c. — A pretty little plant, resembling in habit and appearance the common saw-wort of the 
English woods. The flowers are pink, with bright-blue anthers and pink stigmas. The plant is quite hardy, and 
flowers in August. It is propagated by seeds or dividing the roots ; and it will grow well under the shade of other 
trees. It is a native of the North of Persia, whence it was introduced in 1824. It takes its name of Quinquefolia, 
from its leaves consisting of two pair of leaves and one odd one, which last is generally much larger than the others-

tate, radical leaves cordate, petiolate ; stem-leaves lanceolate, decurrent. 
Head of flowers corymbose, paniculate. Involucre globose. Scales 
lanceolate, rough. 
Description, &c. — This species is a biennial : the stem grows about two feet high, and is much branched ; 
the branches are furrowed, and more or less tomentose. The leaves are also densely clothed with a close white 
tormensum ; the whole plant smells like musk. The flowers are numerous, and of a light reddish-purple. The 
plant is a native of Nepaul, whence it was introduced in 1812. It requires the usual treatment of biennials, 
and will succeed well in the common garden soil, in any clear open situation.

Engraving. — Bot. Mag. t. 2482. | flowered. Involucre globose, rough. Seeds four-sided, warty. 
Description, &c. — This plant, like the last, has a strong smell of musk. It is a hardy perennial, of no great 
beauty, from its single-flowered stem, which gives it a naked appearance. A native of Austria and Carniola, 
but also found near Mount Caucasus, whence it was sent to England in 1817- It will gTow in any common 
garden soil, and in almost any situation.
