The anterior part of the penis is formed by the glans, a bell-shaped structure, apparently continuous with the corpus spongiosum, and having the conical ends of the corpora cavernosa fitted into depressions on its posterior surface.
The corolla is generally funnelshaped, more rarely bell-shaped or tubular; the outer face is often marked out in longitudinal areas, five well-defined areas tapering from base to apex, and marked with longitudinal striae corresponding to the middle of the petals, and alternating with five non-striated weaker triangular areas; in the bud the latter are folded inwards, the stronger areas being exposed and showing a twist to the right.
The plants are mainly shrubs and trees; British representatives are Sambucus (elder), Viburnum (guelder-rose and wayfaring tree), Lonicera (honeysuckle) (see fig.); Adoxa (moschatel), a small herb with a creeping stem and small yellowish-green flowers, is occasionally found on damp hedge-banks; Linnaea, a slender creeping evergreen with a thread-like stem and pink bell-shaped flower, a northern plant, occurs in fir-forests and plantations in the north of England and Scotland.
The plants are bulbous herbs, with flat or rounded radical leaves, and a central naked or leafy stem, bearing a head or umbel of small flowers, with a spreading or bell-shaped white, pink, red, yellow or blue perianth.
The flowers are large, yellow, scented and a little drooping, with a corolla deeply cleft into six lobes, and a central bell-shaped nectary, which is crisped at the margin.
Lapageria, a native of Chile, is a favourite greenhouse climber with fine bell-shaped flowers.
The flowers are large, yellow, scented and a little drooping, with a corolla deeply cleft into six lobes and a bell-shaped corona which is crisped at the margin; they appear in March or April.
On the dorsum of the penis the rim of the bell-shaped glans projects beyond the level of the corpora cavernosa, and is From C. S.

They are freegrowing shrubs with showy bell-shaped flowers, and are favourite greenhouse plants.
