growth resembles that of Acanthus mollis, but the flowers somewhat resemble those of Verbena TiceedieanaiOriiy 
they are larger and produced- in whorls round the stem. The large size of the calyx and involucres, when 
combined with the comparatively small size of the flowers, gives this plant a coarse and weedy appearance. .

jiggregate, upon a receptacle. Corolla four or five cleft. Stamens four.

chaffy. Involucels usually subcylindrical. Limb of calyx attenuated 
into a neck at the ba.se, and ending in five-awned bristles. Flowers I 
Description, &c. — The plants belonging to this genus have all showy flowers, which differ from those of 
Morina, in being produced in heads or masses on a flat receptacle like the daisy, instead of being in whorls round 
the stem. They also show very little of the calyx and involucels. The genus was formerly very extensive ; 
but modern botanists have separated from it two genera, wliich they call Pterocephalus and Cephalaria, the 
Feathered Scabious being the type of the one, and the Siberian Scabious of the other. There are above fifty 
species of Scabious, but only two or three are common in gardens. 
1.— SCABIOSA CAUCASICA, Bieb. THE CAUCASICAN SCABIOUS 
Synonvmes. — S. elegans, Rcem. et Schul.; S. connata, Home ; 
S. caucasica, var. elegans, Dec. 
P2NGRAVINGS. — Bot. Mag. t. 886 ;and our Jig. 1, in Plate 42. 
Specific Character. — Radical leaves lanceolate, acuminated, quite 
entire, glaucous; involucrum very villous; coroHu 5-cleft, radiant ; 
base of involucels elongated, longer than tiie ovate foveolas ; crown of 
seeds short, 25-nerved ; liiub of calyx sessile, with exserted bristles. 
(G. Don.) 
Description, &c. — This very handsome species has a tall, erect stem, with a large head of beautiful blue 
florets in the ray, and whitish florets in the disk, the styles and stamens of which are of a briglit pink. The 
leaves are broad and somewhat silvery. The species is a hardy perennial, flowering in July and August. It is 
a native of Mount Caucasus, whence it was introduced in 1803. 
involucels elongated, equal in length to the linear foveolce ; crown 
of seed spreading, 24-nerved; limb of calyx pedunculated; bristles 
of calyx 5, equal in length to the crown. (G. Don.)

Synonyms. — S. argentea angustifolia, Bauh.

Specific Character. — Suffruticose at tlie base ; leaves linear, lan- 
ceolate, quite entire, of a silvery white; corollas 5-cleft, radiant, base of 
Description, &c. — The flowers are of a light purple ; those of the ray are not so numerous as in S. caucasica, 
and they are the same colour as those of the disk. The stamens and pistils are also of the same colour. The 
leaves are narrow, of a sea-green, and covered with a white silky down. The species is a native of the mountains 
of Europe, whence it was introduced in 1683. It is quite hardy. 
S.— SCABIOSA ATROPURPUREA, Lin. THE DARK PURPLE, OR COMMON SWEET SCABIOUS. 
ovate, lyrate, coarsely-toothed ; cauline leaves pinnate-parted, with 
oblong, toothed, or cut lobes ; heads ovate while bearing tlie fruit ; 
corollas radiant, a little longer than the involucre. (G. Don.)

Description, &c. — This plant is well known in British gardens, under the denomination of the Sweet 
Scabious, from its honey-like smell. Its flowers are produced from June to October. It varies considerably in
