A very handsome and distinct species, remarkable for its tall, strict 



habit, much elongated raceme of pods, large flowers, and the short broad 



pods (compared with those of other species), which are intermediate in 



character between those of Barbarea and Nasturtium, the valves being 



very convex, with a distinct, but not very prominent midrib or keel. It 



was found growing wild in rocky grassy places, and also about cottages.
