Frequent. — a. on walls, rocks, and dry banks. — /3. on shelving 
rocks on Ben Lawers, above the lake. ©. 3 — G. — The var. /3. 
is a very singular one, found by ourselves and others, for many years, 
in the above locality, and never seen to vary : the pouch is as much 
inflated as that of Subularia. 
** Petals slightly emarginate, yellow. Style elongated. Aizopsis DC. 
2. D. aizoides L. ( yellow alpine IF) ; scapes leafless glabrous, 
petals twice the length of the calyx, leaves lanceolate rigid 
glossy keeled and ciliated. E. B. t. 1271. 
Walls and rocks at Pennard Castle, near Swansea. 7/.. 3, 4. — 
Remarkable for its bright yellow flowers and glossy leaves margined 
with hairs. The cultivated plant of this name is a variety with the 
stamens constantly scarcely longer than the calyx, and is D. brachystemon 
DC. : the Welsh plant has the stamens the length of the petals, as in 
wild Continental specimens, and the pouch glabrous. 
*** Petals slightly emarginate or entire, white. Style very short. 
3. D. rupestris Br. (Rock IF.) ; scape leafless or with rarely 
one leaf, pouch or pod oblong-oval, leaves plane lanceolate 
hairy. D. hirta E. B. t. 1338 (not Linn.). 
Mountain summits ; rare. Ben Lawers, Cairngorm, and Ben 
Hope; Scotland. 2f.. 7.- — -The slender perennial root penetrates 
deep among mosses and the crevices of rocks, bearing above many 
short branches, each crowned with a tuft of lanceolate, soft, plane, en- 
tire, or rarely obscurely toothed, hairy fences; their margins ciliate; 
the hairs mostly simple, sometimes branched, on the surface not un- 
frequently stellate. Scapes several from the same root, 1 — 1-j inch 
high, slender, simple, stellato-pubescent. Pedicels short, pubescent. 
Cal. mostly downy. Pouch oval-oblong, pubescent. In cultivation 
the leaves become more glabrous, the hairs on the margin longer and 
more rigid, and the scape 3 — 3^ inches high. 
4. D. inedna L. (twisted- podded IF). ; cauline leaves several 
lanceolate toothed hoary with starry pubescence, pod oblong- 
lanceolate somewhat twisted. E. B. t. 388. 
Mountain rocks, in much less elevated situations and far more fre- 
quent than the last; in Wales, the N. of England, and Scotland. . 
6, 7. — Stem. 4 — 6 inches to a foot or more high, sometimes throwing 
out lateral branches. Lower leaves frequently entire, upper ones 
deeply toothed, almost cut, acute. Pods erect, mostly glabrous. 
5. D. mnralis L. (Speedwell-leaved IF.) ; stem branched, 
leaves ovate obtuse amplexicaul toothed, pouch patent glabrous. 
E- B. t. 912. 
Limestone mountainous countries, on rocks and walls. Craven, 
Yorkshire; Wardon hills, Bedfordshire; Emborough, Somersetshire. 
About Forfar, Edinburgh, and Chelsea, where it has escaped from 
gardens. Blarney Castle, Ireland. ©. 4, 5 Six inches to one foot 
high. Leaves scabrous. Pouch elliptical, shorter than the pedicel.
