Aphanes ( Aphanes called), also called "Ohmkraut" or "Sinau", is a genus of plants from the family of the rose family (Rosaceae).

features

The representatives of the genus Ackerfrauenmantel are annual , herbaceous plants . They do not form a base sheet rosette. The leaves are palmate with three columns, at least the lower ones being stalked. The stipules are fused with the petiole and on the other side with each other and thus form a funnel-shaped tute .

The flowers are small and green. In the European species they are in four to ten (rarely up to 20) flowered axillary clusters. There are four sepals. The outer cup is depending on the section small, missing, or almost the same as the sepals . Petals are missing. The single stamen attaches to the inner edge of the flat disc . The only carpel is also stalked.

The fruits are solitary nuts , the tips of which protrude from the fruit cup.

distribution

The genus is distributed in America and Australia, from Western Europe to Central Asia and in the highlands of East Africa.

Systematics

The genus Aphanes is placed within the rose family (Rosaceae) in the subfamily Rosoideae and in the tribe Potentilleae. Within this, it is sometimes placed together with the species Lachemilla and Alchemilla in a separate subtribe Alchemillinae.

The genus includes 20 species. According to Rothmaler, the genre is divided into three sections :

  • Quadridentatae section : they have no outer chalice. The monopodial shoot is compressed in the vegetative state and then forms a longer section with an inflorescence . It is restricted to East Africa.
  • Section Inaequidentatae : They have a small outer cup . They form a compressed axis, but not a basal leaf rosette from whose leaf axils the flowering shoots arise. It occurs in the entire distribution area of ​​the genus. All European species also belong to this section. The two species native to Central Europe are:
  • Section Aequidentatae : Your outer cup is approximately the same size as the cup. They form a long monopodial axis with a terminal inflorescence. You are limited to the Andes south of the tropic.

Molecular biological studies have shown that Aphanes is a monophyletic group. It is the sister group of the Eurasian lady 's mantle ( Alchemilla ) species.

etymology

The name Aphanes means inconspicuous in Greek and refers to the inconspicuous flowers.
