CLASS X. ORJ)ER Ill.l MOEIIRINOIA. G39 



Root small, l)rancheil. Stems numerous, procumbent at ihc base, 

 and mucb brancbed, round, liairy, leafy, tlirec or four incbes bigh, 

 slender, forming dense green tufts. Leaves opposite, ovate lanceolate, 

 or acute, tapering at tbe base into a sbort footstalk, single ribbed, 

 soraewbat flesby, rougbisb, and ciliated on tbe margin, especially 

 towards tbe base, pale green. Flowers either solitary and terminal, or 

 a few forming a panicle, ratber large, tbe calyx segments lanceolate, 

 acute, witb a pale narrow membranous margin, tbe mid -rib stout, with 

 several slender lateral veins. Petals pure white, ovate, tapering into 

 a sbort claw, half as long again as tbe calyx. Stamens with slender 

 filaments, and yellow ovate anthers, of two cells. Capsule ovate, 

 shorter than the calyx. 



Habitat. — Very rare in Ireland; on Limestone Cliffs at Sea Fin, 

 and Ben Bulben, County of Sligo. 



Perennial ; flowering in June and July. 



This plant is found plentifully on the mountains of France, Switzer- 

 land, and Italy, where it varies in size, and tbe panicle in the number 

 of its flowers, but does not exceed seven or eight, mostly from one 

 to two. 



3. " A. Norve'gica, Gunn, Norivegian Sandwort. Leaves spathu- 

 late, flesby, glabrous, as well as the mucb branched procumbent 

 stems; brancblets one to three flowered ; calyx leaves half as long as 

 the corolla, ovale, acute, witb three to five obscure ribs." 



"Fl. Dau. t. ] 269.— Hooker, British flora, vol. i. p. 182, ed. 4.— 

 A. ciliata, var. /3. Willd." 



" A plant witb altogether the mode of growth and general aspect of 

 A. ciliata, but the leaves are succulent, and everywhere glabrous, and 

 the calyx leaves are broader, and obscurely ribbed." 



Habitat. — " Unst, in the Shetland Islands, first discovered by Mr. 

 Thomas Edmonstone, jun., an enthusiastic naturalist, only eleven 

 years of age, and ascertained to be new to Britain, by Dr. M'Nab, on 

 his visit to those islands, in 1837." 



Perennial ; flowering in July. 



Native specimens of this species we have not seen. The descrip- 

 tion is from the fourth edition of Hooker's British Flora, but we fear 

 the plant is too nearly allied to A. ciliata to constitute a good species.
