184 DECANDRIA — I'ENTAGYNIA. [CotyleJurl. 



narrow-linear acute piano somewhat fleshy tipped with a very 

 minute bristle, stipules ovate cloven, capsule as long as the 

 calyx, seeds compressed angular roughish. E. Bot. t. 852. 



Gravelly or sandy soils, frequent. Fl. June. 0. — Very much branch- 

 ed and s|)reudlng. Stipules, a pair of ovate, acute, white, membrana- 

 ceous scales, united at their base. Flowos numerous, iivthe axils of the 

 upper leaves, solitary. Calyx nerveless, and, as well as the rather short 

 peduncles, glandular and viscid. Petals ovate, red, about as long- as the 

 calyx. Peduncles, after flowering, slightly bent back. — Tlie seeds con- 

 stitute the essential character by which this is known from the following 

 species. 



11. A. marina, Oed. {Sea-side Spurrey Sandtvort); stems 

 prostrate, leaves semicylindrical fleshy awnless, stipules ovate 

 cloven, capsule longer than the calyx, seed compressed smooth 

 with a broad membranous pellucid border. E. Bot. t. 958. — 

 A. rubra, /3. L. 



Frequent upon the sea-coast. Fl. June, July. 0. or $. — Much 

 larger and stouter in all its parts than the last, independent of the ditfer- 

 ence existing in the seed : still I am not sure that these marks ma^'- not 

 depend upon situation. Indeed I have now before me a pubescent 

 variety, gathered in the Isle of Man by Mr Wilson, in which the seeds 

 are rough without a border ; and another with the seeds smooth and 

 without a border.
