The gentian plants (Gentianaceae) are a family of plants in the order of the gentian-like (Gentianales). The approximately 80 to 87 genera with 900 to 1655 species are represented worldwide.
description
Appearance and leaves
They are usually annual , biennial or perennial herbaceous plants , more rarely woody plants: shrubs , trees or lianas . All parts of the plant are hairless.
The mostly opposite, sessile leaves are simple and smooth-edged. In some taxa , the opposite leaves are partially connected by a thickened bar. In some herbaceous species, the leaves are basal concentrated. Stipules are missing.
Inflorescences and flowers
The flowers stand individually, in terminal or axillary inflorescences , mostly it is a simple or compound dichasium , with or without bracts . The hermaphrodite flowers are almost always radially symmetrical and usually four or five-fold. The four or five (rarely up to twelve) sepals are fused at least at the base. The four or five (rarely up to twelve) mostly large and strikingly colored petals are fused at least at the base ( sympetalie ). There is only a circle with four or five (rarely up to twelve) stamens ; they are fused with the corolla tube. Sepals, petals and stamens are always present in the same number per flower. Two carpels have become a top permanent ovary grown. Some species are heterostyle . The pollination is usually by insects ( Entomophilie ).
Fruits and seeds
Usually bilobed capsule fruits are formed with mostly many seeds; Berries with few seeds are very rare . The small seeds contain oil and can be winged or wingless.
ingredients
Bitter substances are often present in the herbaceous taxa in particular ; they are seco- iridoids .
Systematics
This family was established in 1789 under the name "Gentianae" by Antoine Laurent de Jussieu in Genera Plantarum , 141. The type genus is Gentiana L.
