Calyx campanulate, 5-angular, 5-cleft; segments acute,
keeled, at first lanceolate, but continuing to grow till
they become oblong or ovate, pubescent, spreading.
Corolla ringent: upper lip small, ovate, 2-lobed, of a
bluish purple ; lower lip trifid, spreading, with 2 deep
channels underneath, and 2 gibbous ridges above,
white slightly tinged with blue, and on the ridges and
between them are numerous brownish yellow spots,
and clubbed hairs, or pedicled glands. Stamens 4,
2 longer than the others; filaments smooth, attached
to the tu b e ; anthers twin, at first distinct, but when
burst, each pair are attached by the pollen. Germen
smooth, dotted. Style smooth, terminated by a bila-
mellated stigma.
The present little plant is a native of China; the one
from which our drawing was taken, was raised this
Spring at the Nursery of Mr. Colvill, from seeds
received from the Botanic Garden at Berlin, under
the name of Hornemannia bicolor. I t is a hardy
annual; and the plants begin to flower when they are
scarcely 2 inches high, and continue to bloom all the
Summer, and ripen plenty of seeds, growing in pretty
round tufts, the branches spreading prostrate on the
ground in different directions. Being of small growth,
and spreading flat on the ground, it should be sown at
the front of the flower-borders; the proper time for
sowing them, is about the middle of A p ril; if sown
earlier, they will be liable to be injured by the Spring
frost. Though not so showy as some other annuals,
it is still very pretty and curious, and causes a variety,
which is always interesting.
