 bescence very variable. Capsule (inallv oblong, equal to or a little short- 

 er than the calyx. — If the cap.=ule in the European C.arvense (of which 

 we have no specimen^ in fruit) be uniformly twice the length of the calyx, 

 a3 described by DeCandolle, it may be distinct frcm the American plant: 

 but Hooker (in Ji. SjoL) describes the capiule as scarcely longer than the 

 calyx.
