Four to six inches long. Lower part of the stem naked and much 

 branched. Leaves subsecund and subialcate, as observed by Wah- 

 lenberg, their points callous. Flowers large, pure white. Smith 

 says the styles are sometimes 4 and 5, and my capsules have de- 

 cidedly 10 teeth, so that I have no doubt but future observations upon 

 fresh specimens will induce us to remove it to the genus Cerastium, 

 and the MS. name of Mr. G. Don may very well be retained to it. 

 It is common in Iceland, Lapland, and Norway.

 scabrous at the margin, cal. 3-nerved as long as the petals.

I possess only cultivated specimens of this remarkable plant, which 



was first described by Willdenow. He attributes to it single-flower- 

 ed peduncles, but in my plants these peduncles, of which many arise 

 from the extremity of the very short stems, are mostly branched 

 in the middle, whefe they have 2 small ovate acute membranaceous 

 bracteas.

Root long and creeping, slender. Stems decumbent at the fyase, 

 branches erect. Leaves large, decussate, connate, fleshy, shining, 

 a Httle recurved. Flowers solitary, or 2 3 together, in the axils 

 of the upper leaves, nearly sessile. Cal. smooth. Petals white, 

 small, scarcely longer than the cal., distant, broadly ovate, shortly- 

 clawed. Caps, large, roundish, with many black seeds. A species 

 with a very different habit from any other Arenarla.
