 and cymose. Sepals 5. Petals 5, parted almost to the base into 

 narrow segments. Stamens 3 to 10. Styles 3 or 4. Capsule ovoid 

 or oblong, relatively shorter than in Cerastium, dehiscent below the 

 middle into as many or twice as many valves as there are styles. 

 (From the Latin stella, a star, on account of the star-shaped flowers.) 



Annual. 



Stems weak, procumbent; bracts foliaceous 1.5. media. 



Stems filiform, erect ; bracts searious 2. S. nitevs. 



Perennial; bracts foliaceous 3. 5. littoralis. 



1. S. media Cyrill. Common Chickweed. Slightly succulent, 

 with weak procumbent stems, rooting at the lower nodes; lower leaves 

 ovate, acute, rather abruptly contracted into slender petioles, the 

 upper narrower, sessile; floral bracts foliaceous; pedicels slender, 

 deflexed in fruit; petals shorter than the pubescent sepals; stamens 3, 

 5 or 10; styles 3. 



A common weed along fence lines and ditches and shaded half- 

 waste places generally. Feb. -May. Stems with a pubescent line, 

 and petioles of lower leaves hairy. 



2. S. nitens Nutt. Erect, with very slender stems, branching 

 above, 3 to 7 in. high, glabrous or slightly hairy below; leaves linear, 

 acute, sessile, 2 to 7 lines long, or the lowest ovate, 1 to 3 lines long, 

 abruptly contracted into slender petioles nearly twice as long; inflo- 

 rescence strict, the pedicels erect, f in. long or less or some of the 

 flowers quite sessile; bracts searious; sepals scarious-margined, 

 subulate-lanceolate, 2 lines long; petals £ as long as the sepals, some- 

 times none; capsule oblong, nearly as long as the calyx.

 2-cleft valves as there are styles. (From the Latin arena, sand, in 

 which many species grow.) 



Low annuals. 



Leaves lanceolate, rather broad at the very base, 2 lines long
