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- 

 most alternate. Flowers scattered or in terminal capitate clusters.

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

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

 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 Euli-
