Arabis stricta was first described under that name by our countryman Hudson; and Villars in his Flore
du Dauphine has subsequently given this plant as the Turrit is Raii, in the full persuasion that it is the one mentioned
by Ray as his Cardamine pumila, bellidis folio, alpina-, and Sir James Smith is inclined to be of the same
opinion; though that synonym has so frequently been quoted under the Cardamine bellid folia. These two plants
are nevertheless widely different in the shape and superficies of the leaf. To thé Arabis hispida (Cardamine has-
tulata Engl. Bot.) and Cardamine petraa, both of winch we have received from Iceland, our plant has a much
closer affinity ; but it may be at all times distinguished by the leaves being much more toothed, more hispid, and
by the colour of the flowers, which in this is white, in the other of a blueish or purple tint. The figure of the leaves,
too, will alone suffice to distinguish Arabis stricta from Arabis thatiana, which is moreover an annual plant, and
has the hairs or bristles of the leaves universally trifid, whilst those only are so in Arabis stricta which clothe the
underside of the leaves.
The Turrit is ciliata of Schleicher is quoted by Decandolle as a variety of this plant, although we have the authority
of Willdenow and Smith for.considering them distinct, the latter of whom has figured Schleicher’s plant in
English Botany under the name of Turritis alpina. When cultivated in gardens, our plant assumes very much
the appearance of the more common Turritis hirsuta, which is very properly made an Arabis in the last edition of
the Hortus Kctoensis; but its stems are remarkably leafy.
