Description

Vegetative characteristics

Anchusa species grow as single-, two-year to perennial herbaceous plants. The roots and underground shoot parts contain alkannin (also called Anchusin ), one also with other Raublattgewächsen ( Alkanna, Echium, Lithospermum, Onosma ) contained red to violet dye. The hair is usually rough or rare soft -fitting. The change-constant leaves are simple.

Generative features

The terminal, zymösen inflorescences contain bracts. The hermaphrodite, five petals are radial symmetry to slightly zygomorphic. The five sepals are fused in the lower third or on the ground; they are sometimes slightly enlarged in fruit ripening. The blue to purple or yellow petals are united at the base to a straight to curved tube; the throat appendages are scaly or papillose and short haired. The five wheel-shaped to bell-shaped corolla lobes protruding are equal or unequal. It's just a circle with five stamens present; they are adherent to the corolla tube in their half or less, and they do not extend beyond the crown. The stamens are short and the anthers are ovate - oblong. Two carpels are fused into a superior ovaries; it is divided by false septa in four Klausen. The stylus does not extend beyond the crown, ending in a capitate, two-piece scar.

Are formed Klaus fruits that seeded in four disintegrate nutty Klausen. The Klausen are straight, kidney-shaped or ovate wrong and have a netzrunzelige surface; approach the scar is located on the ground or in the vicinity and has an annular thickened and hardened edge.

The basic chromosome number of x = 8, in Anchusa Thessala but only x = 6

System

The genus Anchusa S. L. is monophyletic according to molecular genetic studies; in addition it was necessary some smaller genera ( Gastrocotyle, Phyllocara ) split off or spin off some species existing in other genera. The s.str in the genus Anchusa. remaining species are divided into five subgenera, their distribution is also advocated because they are paraphyletic. Based on this classification are primarily fruit characteristics. The subspecies listed in some species were often performed in older literature as a species. Overall, there are about 30 to 50 Anchusa species:
