Calyx and rotate corolla 5 -parted ; the divisions of the latter broad. Filaments 

 slender, bearded : anthers ovate. Style slender : stigma small. Capsule globose, 

 opening by a transverse line round the middle, the top falling off as a lid. Seeds 

 numerous, immersed in the globular placenta. Spreading or prostrate herbs ; with 

 mostly opposite or whorled leaves, disposed along the whole length of the stems and 

 branches, and flowers on axillary peduncles. Naturalized along both coasts, but not 

 indigenous to Xorth America.

 cles, commonly opposite, sometimes in threes : flowers opening only in sunshine, 

 scarlet or purple, sometimes blue or white : petals obtuse, fringed with minute teeth 

 or stalked glands.

Calyx 4 - 5-parted ; the lobes narrow. Corolla very small, shorter than the calyx, 

 4 - 5-cleft ; the tube globular ; the lobes acute. Filaments short : anthers cordate- 

 ovate. Capsule as in Anagallis. Seeds minute. Small and low annuals, with 

 mostly sessile entire leaves, and minute flowers in the axils : the inconspicuous 

 corolla white. 



1. C. minimus, Linn. An inch to a span high, simple or diffusely branched, 

 glabrous : leaves alternate, obovate, 2 or 3 lines long, narrowed at base : flowers 

 almost sessile, the parts in fours : calyx-lobes slender-subulate. C. lanceolatus,
