130 ENGLISH BOTANY. 
Wales at one time, and is now practised at Llanberis. The square stones of the 
floors are ornamented by being crossed at right angles with two broad black lines, 
which somewhat resemble mosaic-work. This effect is produced by strongly rubbing 
the stone with a handful of leaves of the Foxglove, when the juice dyes this black 
stain. 
Tribe IV.— ANTIREHINE^]. 
Corolla tubular, bilabiate, usually saccate or spurred at the 
base on the outer side ; upper lip covering the others in bud. 
Stamens 4, didynamous, rarely with a small scale, representing 
the fifth stamen. Leaves alternate, or the lower ones often verti- 
cillate or opposite. 
GENUS IV— A NTIRRHINUM. Toumef. 
Calyx 5-partite. Corolla tubular, bilabiate and personate ; 
tube saccate at the base on the outer side ; limb with the upper 
lip erect, 2-lobed, the lower spreading, 3-lobed, with the middle 
lobe the smallest, and with a large hairy palate pressed 
against the upper lip and closing the mouth of the flower. Sta- 
mens 4, didynamous, included ; anthers 2-celled. Capsule 2-celled, 
obliquely ovoid, with the upper cell opening by a single pore 
and the lower by 2, or globose and with each cell opening by 
a single pore. Seeds numerous, minute, not winged. 
Herbs or undershrubs, with most of the leaves alternate, but 
the lower ones generally opposite. Flowers generally handsome, 
solitary and axillary, or disposed in racemes. 
The name of this genus of plants is derived from two Greek words, avn (anti), 
instead of, and piv (ri)i), a snout ; so called because the flower in some ot the species 
is said to resemble the snout of a calf.

Stems erect, much branched, shrubby towards the base ; branches 
erect. Leaves mostly opposite, oblong-elliptical or oblong-strap- 
shaped, attenuated into short indistinct petioles ; the upper ones 
narrower and nearly sessile; all entire and glabrous. Mowers race- 
mose. Bracts ovate, acuminate, shorter than the pedicels. Pedicels 
erect, usually longer than the calyx, thickly clothed with gland- 
lipped hairs. Calyx-segments slightly unequal, oval or oval- 
orbicular, obtuse, thickly clothed with gland-tipped hairs. Corolla
