Sandy fields; Norfolk, Cambridgeshire, Oxfordshire, &c. Cram- 

 mond Island, and near Petticur Harbour, Frith of Forth ; Scotland 



(scarcely indigenous and not found of late years). 0. 5, 6. Stems 



4 — 6 inches high, glabrous, throughout remarkably slender, especially 

 the peduncles. Petals varying a little in length, sometimes obovate. 

 Don alone is said to have seen this in Scotland, but his published 

 specimens are from England.

5. A. fastigidta Sm. {level-topped S.) ; stems erect straighl , 

 leaves fascicled subulate-setaceous erect, flowers fascicled, sepals 

 much acuminate (white) with two central (green) ribs twice 

 as long as the obovate petals. E. B. t. 1744. .Alsine Fenzl. 



On rocks in the mountains of Clova, Angusshire, and also Fifeshire : 

 Mr, Don. 0. 6.— Sir J. E. Smith rightly distinguishes this, the A. 

 fasciculata of Jacq. and De Cand., from the very rare species so named 

 by Gouan. The Clova specimens which we possess from Drummond 

 as well as Don, are only distinguishable from the A, mucronata of 

 DC, of which this is perhaps a variety, by the more compact inflo- 

 rescence, annual (or biennial) root, and erect stem: it is also found in 

 Switzerland and the Pyrenees in warm rocky places, at no great ele- 

 vation. It is very peculiar in habit, and quite unlike any othes* 

 British species. Seeds ''beautifully toothed like a wheel, each on a 

 long slender stalk." Sm,

6. A. Norvegica Gunn. (Norwegian S.) ; leaves spathulate- 



obovate fleshy glabrous, sepals half as long as the corolla ovate

On Serpentine Hill, Unst, Shetland ; Mr, T. Edmonstone, Jan. 

 If.. 7, 8. — Whole plant perfectly glabrous. Stems much branched, 

 procumbent; branchlets 1 — 3-flowered. This has altogether the 

 mode of growth and general aspect of A. ciliata ; but the leaves are 

 succulent and without any ciliee, and the sepals are broader and only 

 obscurely ribbed* 



7. A. ciliata L. (fringed S.} ; leaves spathulate roughish 

 ciliate, sepals half as long as the corolla lanceolate acute with 

 3 — 5 prominent ribs. E. B. t. 1745. 



Limestone cUffs, near Ben Bulben, a mountain in Sligo, Ireland. 

 ^. 6 — 8. — Stems much branched, procumbent or ascending, rough- 

 ish, downy ; branchlets 1 — 5-flowered. Petals ovate. 



8. A. serpyllifolia L. (Thyme-leaved S,) ; leaves ovate acute 

 subscabrous sessile, calyx hairy its outer sepals 5-ribbed about 

 as long as the corolla. E. B. t. 923.
