[Illustration]
This is a climbing plant, cultivated in America and Europe. Leaves large,
entire, cordate, alternate, on long petioles, generally arising from the
axil of the flower-bearing branches. Calix with five unequal folioles,
the three outer ones sharp, the two inner ones oval and foliaceous. Corol
white, large expanding into a large circular limb. Stamens five, adhering
by their filaments to the tube of the corol which is shorter than the
stamens. Anthers linear acuminate. The base of the ovary is surrounded
by a glandular disk; style very long, filiform, terminated by a shaggy,
bilobate stygma; fruit with a coriaceous tegument. There are two or three
flowers on the flower-bearing pedicels; they resemble a trumpet in shape,
whence their Brazilian name “herva trombetta.” This plant blossoms in the
summer-months. We employ the flower.
