Cerastium n. sp. Cespitose, pubescent. Leaves lan- 
ceolate-oblong erect, acute shorter than the joints : flowers 
are long terminal peduncles; leaflets of the calyx oblong ; 
corolla Mee two-cleft twice the lengthof the calyx. San-

This ey is allied to C. termifolium of Pursn, but the 
leaves are much broader, and the calyx obtuse. ne pe- 
tals are only twice instead of thrice the length of the calyx. 
With the C. glutinosum of Nuttall, it has also much affinity, 
but that ar ae is much larger and viscous, and the capsule is 
double the length calyx, while in our E Bigot it appears to be 
oblong and shorter than the calyx
