4. LINANTHUS Benth. 

 Ours low or slender annuals. Leaves opposite, palmately divided 

 to the base into narrowly linear or filiform divisions (almost seeming 

 as if in whorls in some species), rarely entire, rarely with some upper-

 Corolla subrotate, funnelform, or short-salverform. Stamens equally 

 inserted on the corolla. Capsule with few to many seeds in each cell. 

 (Greek linon, flax, and anthos, flower.)

 form pedicels (except in the first); stems dichotomously branching. 

 Corolla short salverform, white or nearly so, its lobes conspicuously con- 

 volute in the bud ; stamens inserted below the middle, included : 

 flowers terminal or in the forks, on short stout pedicels or subsessile : 

 calyx cylindrical, white-scarious between the ribs.— Subgenus Eri.i-
