Aphanes

Usually arable lady's mantle ( Aphanes arvensis)

Acker lady's mantle ( Aphanes ) is a genus of flowering plants of the rose family ( Rosaceae ). The genus is also called Ohmkraut or Sinau.

Features

The representatives of the genus arable lady's mantle are annuals, herbaceous plants. They do not form basic leaf rosette. The leaves are palmate columns, at least the lower ones stalked. The stipules are fused together with the petiole and on the other side and so form a funnel-shaped Tute.

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

The fruits are single-seeded nutlets that stick out with their head out of the fruit cups.

Dissemination

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

System

The genus Aphanes is placed within the rose family ( Rosaceae ) in the subfamily Rosoideae and in the tribe Potentilleae. Within this it is still sometimes placed in its own subtribe Alchemillinae together with the species pool Milla and Alchemilla.

The genus includes 20 species. After Rothmaler the genus is divided into three sections:

  • Section Quad Ride Bidentatae: they have no outer calyx. The monopodial shoot is compressed in the vegetative state and then forms a longer section with inflorescence. It is limited to East Africa.
  • Section Inaequidentatae: They have a small outdoor chalice. They form a compressed axis, but no reason rosette of leaves from whose axils spring the flowering instincts. It occurs throughout the distribution area of the species. In this section are all European species. The two native species in Central Europe are: Usually arable lady's mantle ( Aphanes arvensis) and
  • Kleinfrüchtiger arable lady's mantle ( Aphanes inexspectata )
  • Aphanes minutiflora occurs in the Mediterranean.
  • Section Aequidentatae: Your outer cup is approximately the same size as the calyx. They form a long monopodial axis with terminal inflorescence. You are limited to the Andes south of the Tropic.

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

Etymology

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