9.— DIGITALIS CANARIENSIS, Lin. THE CANARY ISLAND FOXGLOVE. 
SvsoNYME.— Isoplexis canarienais, Lin. of the corolla bifid, acute ; lower lip lanceolate, nearly equal j leaTes 
Engravings. — Bot. Reg., t. 48 ; and oar fig. 1, in PI. 76. lanceolate, serrated. 
Specific Character. — Segments of the calyx lanceolate, upper lip 
Description, &c. — This species is properly a shrub, and will grow to the height of five or six feet ; but as 
it is generally raised from seed, and will flower the first, or at raost the second year, it may, for all practical 
purposes, be considered as a biennial, and treated accordingly : that is, the seeds may be raised on a hot-bed, 
kept in a pit during the first winter, and planted out in April in a warm, sheltered situation, where they will 
begin to flower in May, and continue the greater part of the summer. After the plant has ripened its seeds, it 
may be suffered to die, which it will do, as soon as the cold weather sets in, as it cannot sustain the severity of 
an English winter without protection. It is a native of the Canary Isles, whence it was introduced in 1698. 
10.— DIGITALIS OBSCURA, Lin. THE OBSCURE DIGITALIS. 
SvKONYMES D. hispanica, Tourn. ; the Willow-leaved Fox- | Specific Character. — Leaves linear.lanceolate, acuminate, entire, 
glove. I glabrous. Segments of the calyx oblong- lanceolate, acute; upper lip 
Engratino. — Bot. Mag., t. 2157. | of the corolla biftd ; central lobe of the lower limb ovate. 
Description, &c. — This is a very handsome species ; the flowers being red on the outside of the tube, and 
of a bright yellow veined with red within. The stem is woody at the base ; but the plant is generally 
considered a perennial ; as, though the stem is woody, it is not permanent, and is generally killed down to the 
ground every winter, though a fresh stem springs up from the root the following spring. It is a native of Spain, 
and was introduced in 1778. 
OTHER SPECIES OF DIGITALIS. 
There are several other species ; but those which have been enumerated are the principal of the perennial 
kinds. 
GENUS II. 
ANTIRRHINUM, Lin. THE SNAP-DRAGON. 
Lin. Syat. DIDYNAMIA ANGIOSPERMIA. 
compressed, rather hairy at the base, having the sterile or fifth one very 
short or wanting. Stigma two-lobcd. Capsule two-celled, woody, ovate, 
or pear-formed, incurved at top, opening by three holes, or an irregular 
foramen, under the top. Seeds oblong, truncate, minute; testa black, 
more or less engraven, or wrinkled. (G. Don.) 
Generic Character.— Calyx five-parted, oblique. Corolla personate; 
tube ample, a little compressed, saccate at the base, and furnished with 
two parallel and interrupted lines of hairs inside beneath the palate ; 
lobes of the upper lip erect, and often adpressed to the back by turns ; 
lower lip spreading, having the middle lobes smaller than the lateral 
ones, with an ample bearded palate, which closes the throat. Stamens 
Description, &c. — All the species belonging to this genus arc either perennial or annual plants ; generally 
with ornamental flowers, and natives of Europe. Many of the smaller species which were formerly considered to 
belong to this genus, have been removed by modern botanists to the genus Linaria. The name of Antirrhinum 
signifies like a snout, and hence also one of the vulgar English names is Calfs Snout. Both these names are 
evidently taken from the form of the flower ; as is the common English name of the plant, Snap-dragon.
