The disc pods ( Peltaria ) form a genus of plants in the cruciferous family (Brassicaceae). The German common name Scheibenschötchen is derived from the shape of the fruit, just like Peltaria , which is derived from the Greek word πέλτη = pelte for small shield.
description
The disc pods are perennial herbaceous plants or subshrubs . The leaves are distributed on the stem. The plants are bare or covered with sparse fork hairs and often have blue-green frosting. The disc pods have (a few) long-stalked basal leaves and sessile stem leaves with an eyed or narrowed base.
The hermaphrodite flowers are fourfold. The four sepals have a membranous edge at the tip. The four white or reddish petals are nailed short.
The fruits are pods that hang on a short stem, are disc-shaped and completely flat; they contain one to three seeds. The ripe fruits are very raised, reticulated and surrounded by a peripheral nerve.
Distribution and systematics
The disc pods occur from Southeastern Europe over the Middle East to Central Asia.
A synonym for Peltaria Jacq. is Leptoplax O.E.Schulz .
After Warwick, Francis and Al-Shehbaz and Kubitzki, the genus includes four species, two of which occur in Europe.
