CABYOPHYLLACEiE. 125 



Plant growing in small dense tufts ; stems scarcely an inch 

 high, including the jieduncles, which are shorter than in any 

 of the preceding species, not being more than twice or thrice 

 the length of the calyx. The leaves have an extremely indistinct 

 mucro, in this differing both from S. saxatilis and S. subulata, from 

 which also its more compact manner of growth and peduncles not 

 reflexed after flowering form sufficient distinctions ; indeed, it has 

 much more the habit of S. maritima than of any other of the 

 British species of Sagina ; but, besides being a perennial and having 

 a barren central rosette, it has pentamerous flowers, the leaves 

 more tapering at the apex, the peduncles much shorter, the petals 

 very much larger, and the styles erect after flowering.

j yl^ootstock slightly branched. Stems rather few, the primary 

 or central one reduced to a barren tuft of leaves, never producing 

 flowers, the lateral ones curved, ascending, not rooting at the 

 ise. Lower leaves crowded, the upper ones more remote, gene- 

 illy producing fascicles of leaves in their axils; all somewhat 

 /fleshy, subulate, abruptly pointed with an indistinct mucro. Cyme 

 few-flowered. Peduncles rather short, erect, glabrous or with 

 gland-tipped pubescence. Sepals 5, oval, concave, very obtuse, 

 glabrous or with gland-tipj^ed pubescence applied to the capsule 

 when mature. Petals much longer than the sepals, sometimes 

 nearly twice as long. Capsules a little longer than the sepals. 

 Seeds roundish-obovate, rugose, with distinct tubercles. Plant 

 glabrous or with the upper part of the stem, bases of the leaves, 

 .calices glandular-hairy. 



In damp sandy places. Not uncommon, and generally dis- 

 tributed.

 and Autumn. 



Plant growing in small lax tufts, with the lateral stems spread- 

 ing in a circle, decumbent at the base, 3 to 8 inches long, having 



a peculiar knotted aj)peai-ance (from which the plant takes its 

 specific name) caused by the small bundles of leaves produced from 

 the axils of the ujiper stem-leaves. Plowers j inch across, white, 

 very much larger than any of the other species of the genus. The
