description

Vegetative characteristics

The species of the genus pepper are shrubs or trees , which are occasionally semi-herbaceous, rarely climbing; they are often thickened at the nodes . The alternate leaves are simple, with a few exceptions with entire margins, mostly stalked and in a few species they are shield-shaped. Often the adhesion of the leaf blade with the petiole starts a few millimeters deeper on one side than on the opposite side. The upper side of the leaf is smooth to wrinkled or blistered, the underside of the leaf is pitted. The leaves are hairless or barely to densely hairy, the hairs are often rough. There are often sparsely to dense, glandular points on the leaves. The nerve is either palm-like or more frequently pinnate-veined from the lower half to the lower two-thirds, sometimes also completely pinnate-veined. Often fine intersecting connections are formed between the nerves or nerve tracts that merge into one another. The leaf stalks can have different lengths, and they are rarely absent. Usually they are at least at the base, often more or less sheath-like notched up to the leaf blade. The edges of these notches are winged with a narrow or conspicuously wide wing, sometimes it seems to be missing entirely. The stipules are fused with the petioles.

Inflorescences, flowers and fruits

Black pepper fruits ( Piper nigrum )

The ear-like inflorescences are opposite the leaves and are cylindrical or, rarely, spherical or almost spherical. They have a diameter of 1 to 10 mm, can occasionally be thicker and have a length of up to 50 cm and more. The length of the inflorescence stalks can be between less than 5 mm and a few centimeters. The axis of the inflorescence between the flowers is usually somewhat grooved, the grooves are flat and smooth or warty to frayed. The flowers are often crowded in the armpits of variously shaped bracts , which are sometimes hairless, but usually tomentose or fringed. The sessile flowers are hermaphroditic in the American species, incomplete (unisexual) in the ancient world. Most of the species are dioecious ( dioecious ), more rarely monoecious ( monoecious ), separate sexes. There are two to five stamens in the male and hermaphrodite flowers . Two to five carpels have grown together to form an upper ovary with two to five stigmas . These are round to thread-shaped, perched or standing on a short and thick to elongated and slender stylus . The stone fruit-like , sessile fruits are shaped differently and single-seeded. They have a thin pericarp and a somewhat hardened endocarp .

The genus Piper was established in 1753 by Carl von Linné in Species Plantarum , 1, p. 28 and Genera Plantarum , 5th edition, 1754. Piper nigrum L. was specified as the lectotype species by Albert Spear Hitchcock in 1923 in the American Journal of Botany , Volume 10, p. 513.

There are 1000 to 2000 species in the genus Piper . There are about 60 species in China.

Here is a selection of the types:
