332 DECANDRIA— PENTAGYNIA. Cerastium. 



ovate -oblong 3 the lower ones smoothest. Panicle spreading, 

 viscid. Flower-stalks longer than the calyx, bent down as the 

 flowers fade, but finally erect. Calyx-leaves rough and gluti- 

 nous, obtuse, with a broad white shining margin. Pet. pure 

 white, conspicuous, though shorter than the calyx, slightly 

 cloven at the tip, sometimes cut at the side, but irregularly and 

 accidentally. >S7rtm. 5, very rarely more. Styles d. Ca/)5. slightly 

 curved, twice as long as the calyx. Seeds rough, compressed. 



/3 differs slightly in the size of its petals, which are cloven about a 

 third of their length. 



Haller attributes 3 styles only to his n. 894. 1 have never seen or 

 heard of fewer than 5 in the Cerastium semidecandrum, which is 

 indubitably a most distinct species, displaying itself on every 

 wall in the early spring, and withering away before the viscosum 

 begins to put forth its far less conspicuous blossoms. 



4. C. tetrandrwti. Four-cleft Mouse-ear Chickweed. 



Hairy and somewhat viscid. Flowers four-cleft, with four 

 stamens. Petals inversely heart-shaped, shorter than 

 the taj:)er-pointed calyx, which is nearly as long as the 

 capsule.
