7 ARENARIA L. Gen. n. 569. 
Mostly low, often tufted annual or perennial herbs ‘with ses- 
sile subulate and more or less rigid leaves without stipules and 
small white flowers in paniculate or capitate cymes in spring and 
summer. Sepals 5, rarely 4. Petals as many as sepals, rarely 
wanting, entire or emarginate. Stamens twice as many as pet- 
als. Styles 3, rarely 2,4 or 5, opposite as many sepals. Cap- 
sule globose or short-oblong, dehiscent into as many 2-cleft 
valves as styles, few to many-seeded. Seeds laterally compressed 
or reniform-globose.
