Matthiola incana (L.) R. Br. (syn.: Cheiranthus incanus L.) (Medit., W-Eur.) – An exceptional escape from cultivation. Recorded on a steep dune slope in De Panne in 2012 (scattered individuals under scrub, probably more or less naturalised).
Matthiola incana is widely cultivated for its attractive, highly scented flowers. In general appearance (and especially in the non-flowering stage) it is much reminiscent of Erysimum cheiri. Pinkish flowered variants of the latter are best separated from Matthiola incana by their indumentum: hairs are predominantly stellate or dendritic in Matthiola while medifixed (with two branches) in Erysimum.
