On mountains in Ireland. 



Upon the limestone cliffs of a high mountain adjoining to Ben 

 Bulben, in the county of Sligo. Mr. J. T. Mackay. 



Perennial. August, September. 



Root copiously branched at the crown, with very numerous re- 

 cumbent, leafy, round, downy stems, about a finger's length at 

 most, composing dense, bright green tufts. Leaves in pairs 

 crossing each other, recurved, spatulate, obtuse, single-ribbed, 

 somewhat fleshy, roughish j tapering, and most evidently 

 fringed, at the base. Fl. terminal, large and conspicuous, on 

 long, mostly solitary, stalks, clothed with short recurved hoary 

 pubescence. Calyx-leaves ovate, acute, concave, hairy, green, 

 with a strong keel, and 2 or 3 close ribs at each side ; the mar- 

 gin membranous. Pet. of a brilliant white, spreading, longer 

 than the calyx. Caps, short, ovate, of 6 valves. 



A. multicaulis of Linnaeus appears to me the same plant in a less 

 luxuriant state. By culture the stems become forked, bearing 3, 

 4 or 5 flowers. 



** Stipulas membranous. 



9. A. rubra. Purple Sandwort. 



Leaves linear, bristle-pointed. Stipulas membranous, sheath- 

 ing. Seeds compressed, angular, roughish.

Annual. July, August. 



Root tapering. Stems numerous, prostrate in a circular form, flac- 

 cid, branched, round, leafy, smooth, except towards the ex- 

 tremity, where they are generally clothed with prominent glan- 

 dular hairs, such as cover the Jlower-stalks and calyx. Leaves 

 mostly opposite, often in pairs, narrow, flat, glaucous, or hoary, 

 rather succulent, acute, with a small terminal bristle ; each with 

 a pair of shining, combined, membranous stipulas at the base. 

 FL on simple stalks, finally reflexed, from the forks of the stem.
