Diplotaxis (plant)

Narrow- double Same ( Diplotaxis tenuifolia )

The plant genus of the double seeds ( Diplotaxis ) belongs to the family of the cruciferous plants (Brassicaceae ).

Description

Diplotaxis species grow as an annual or biennial or perennial herbaceous plants. They are glabrous or with simple hairs. Their leaves are mainly fiederlappig to pinnately lobed, rarely undivided.

The hermaphrodite, radial symmetry flowers are cruciform. The sepals are from upright and are not or only slightly slumped. The petals are yellow, rarely white; the stamens easy. The flowers have four nectaries; depending on a flat, kidney- shaped on the inside of the shorter stamens and a tongue-shaped on the outside of the longer stamens. The fruit is a linear, somewhat compressed pod with a short beak; the fruit valves have a distinct midrib. Seeds are abundant formed, they are double row. The cotyledons are folded rinnig and longitudinally.

Dissemination

The distribution area extends from the Macaronesian islands on the northern and eastern Africa, southern Europe, western and central Europe to southeastern Europe, western Asia and the Arabian Peninsula to Pakistan and Afghanistan to Nepal in the Himalayan region. Most of the Diplotaxis species are widespread in the Mediterranean and the North African desert. In Central Europe, there are three types: wall - double Same ( Diplotaxis muralis ), Narrow double Same ( Diplotaxis tenuifolia ) and Rod Double Same ( Diplotaxis viminea ).

System

1821 was established by Augustin de Candolle Pyrame the genus in Systema Naturae Diplotaxis, 2nd Edition, Volume 2, page 628. The genus name Diplotaxis derives from the Greek: diplo - for double and taxis for arranged, this refers to the number of rows in which the seeds are placed in each of the fruit trays. A synonym for Diplotaxis is Pendulina Willk .. The genus Diplotaxis DC. belongs to the tribe Brassicaceae in the family Brassicaceae.
