In marshy ground, especially on watery sandy heaths, common. 



Annual. July, August. 



Root of many downy fibres. Herb pale green, in /3 reddish, various 

 in luxuriance. Stems numerous, crowded, erect or spreading, 

 from 3 inches to a foot or more in height, round, smooth, some- 

 what branched, leafy, especially at the lower part ; panicled 

 above. Leaves linear, narrow, ribbed, angular, channelled, acute, 

 dilated at the base. Bracteas very slender, erect, much shorter 

 than the panicle, which is forked, with many racemose, lax, 

 greatly elongated, branches. Fl. nearly sessile, mostly solitary, 

 erect, pale and silvery, with 2 or 3 vei"y white pellucid bracteas 

 at their base. Calyx-leaves lanceolate, taper-pointed, acute, 

 green at the back, with 2 ribs, and sometimes an intermediate 

 keel, the margins, beyond the ribs, broad, membranous, and 

 shining. Caps, elliptic-oblong, triangular, reddish-brown, blunt- 

 ish, generally much shorter than the calyx, and always of a 

 much narrower figure than in any of the foregoing. 



Haller's third variety, G. holosteum alpinum minimum of the 

 Bauhins, abundant, as they say, on mount St. Bernard, from 

 whence I have it, has the capsule nearly as long as the calyx, 

 but otherwise scarcely differs from our common more dwarf and 

 spreading varieties. The 2 ribs of the calyx vary in this^ as in 

 ours, in being either near together, or more remote. 



In germination the young plant elevates the seed considerably 

 above ground, so as to look like a moss with capsules ; as re-
