90 BRITISH BOTANY. 



barren leaves in their axils. Leaves glabrous, subulate or awned. 

 Peduncles hooked at their summit after flowering, then erect, 

 scarcely longer than the internodcs (portions of the stem between 

 the joints). Sepals ovate -obtuse, spreading after flowering. 

 Petals about half as long as the sepals, sometimes absent. Cap- 

 sule ovate, obtuse, longer than the calyx. Seeds small, reniform, 

 furrowed on one side. 



At the foot of walls and in moist places. Perennial; May- 

 October. 



S. maritima, Don. 'Sea Pearlwort. — e.b. 2195. l.b.s. 168. 

 A. 14. C. 40. Lat. 50-61°. Alt. 0- ? Tern. 52-46°. 



Stems several, glabrous, spreading or erect, bearing a rosette 

 of barren leaves in their axils. Leaves plano-convex (rounded 

 on one side and flat on the other), linear-lanceolate, scarcely api- 

 culate (very short point), never awned, glabrous, very short. 

 Peduncles long, straight, smooth, ascending. Sepals obtuse, not 

 mucronate. Petals lanceolate, nearly as long as the calyx, rarely 

 absent. Capsule erect, subsessile. 



Seashore. Annual; May-September, 



Grenier, ' Flore de France,' describes a variety, var. /9. elon- 

 gata, which has long and almost solitary stems. Mr. Babington 

 states that the petals are absent, and Fries that his plant is pro- 

 duced on the Norwegian mountains. 



S. apetala, Lin. Apetalous or Erect Pearlwort. — e.b. 881. 

 L.B.S. 169. 



A. 15. C. 60. Lat. 50-57°. Alt. 0-200 yds. Tern. 52-47°. 



Stems spreading or erect (elongated, forked, with ascending 

 branches), never rooting, glabrous or downy, branching from the 

 root. Leaves subulate or awned, ciliate at the base, glabrous or 

 pubescent like the stem. Peduncles about as long as the inter- 

 nodes (see S. maritima), straight or slightly curved at the sum- 

 mit, often invested with glandular hairs. Sepals oblong, spread- 

 ing and cruciate when ripe, the two outer are slightly mucronate. 

 Petals very small or absent. Capsule longer than the calyx. 



At the base of walls, generally in dry places. Annual ; May- 

 September.

S. ciliata, Fr. Stems spreading. Leaves linear, awned, fur- 

 rowed, subulate-awned, rarely ciliate. Peduncles as in S. apetala 

 (reflexed after flowering and ultimately erect) . Sepals adpressed
