Occasional on rock ledges and cliffs, prefers limestone Flower diameter c 3-4 mm. Pods c 1.5-5 cm long Skye ID: Typical Crucifer flowers. Petals not notched, somewhat narrow. Leaves all undivided (may be distantly and shallowly toothed, or untoothed), those of the basal rosette narrowing to a short stalk, those on the stem unstalked, usually clasping, and held upright. Pods narrow and straight, not twisted, held erect, appressed to stem. Other features: In the absence of pods it can be hard to tell from other Crucifers, particularly Twisted Whitlow-grass, which shares many of its characters but has notched petals. Both species are very hairy and both have numerous stem-leaves which they hold upright, close to the stem. The very rare Alpine Rock-cress has petals rather more rounded, not so narrow or straight-sided, and considerably larger. It also has the pods held away from the stem and spreads by stolons which the present species does not. |
