116 ENGLISH BOTANY. 



sides having on the disk anastomosing ridges, forming narrow 

 openings, and round the margins a slightly rugose hand composed 

 of flattened tahular tuhcrcles. 



In hoggy places. Very rare. By the banks of the stream on 

 the sugar-Hmestone near the top of "Widdy Bank FeU, Teesdale, 

 Durham, from whence I am favoured with specimens by Mr. J. G. 

 Baker. 



England. Perennial. Summer. 



Plant growing in small tufts, with the leaves J to -| inch long, 

 frequently falcate. The flowering stem 2 to 4 inches high, nearly 

 leafless. Peduncles often 1 inch or more long. Flowers f inch 

 across. Seeds very unlike those of any of the previous species ; 

 the ridged portion of the disk fuscous ; the marginal band reddish 

 brown. 



This plant has quite the habit of a Sagina, in which genus it 

 was originally placed by Swartz, tliough there is a technical dis- 

 tinction in the 3-valved capsule which has caused its removal to 

 Arenaria or Alsine ; but, in consequence of this change of place, it 

 becomes necessary to use the name " uliginosa," as there is a well- 

 known American plant, Arenaria (Alsine) stricta, of Michaux, 

 with which it might otherwise be confounded. 



Bog Sandwort. 



GENUS XII.— S A G I N A. Linn. 



Sepals 4 or 5, concave, spreading when in flower. Petals as 

 many as the sepals, entire or slightly notched, sometimes very 

 small or entirely absent. Stamens 4 when the sepals are 4 ; 5 to 10 

 when the sepals are 5. Styles as many as the sepals. Capsule 

 splitting to the base into as many valves as there are sepals. 



Small annual or perennial plants, with short filiform or subu- 

 late leaves, frequently with fascicles of leaves in the axils. Flowers 

 small, white, generally with long pedicels, in terminal cymes often 

 reduced to single flowers. 



In Latin the generic name of this plant signifies fatness, fattening food ; and 

 it -was supposed by Liunseus that the species possessed this quality, and tkttened sheep 

 feeding on them.
