Stem smooth, angular, 12 to 18 inches high ; the branches 

 spreading. Rachis of the leaf enlarged at the base and furnished 

 with many closely-placed leaflets which clasp the stem, and, as 

 WaUroth justly remai'ks, resemble a comb ; the next leaflets 

 generally small and short, simple or simply forked ; succeeding 

 leaflets becoming gradually longer and more compound ; all 

 placed on the rachis at pretty regular intervals, except the 

 closely-placed basal ones, which are not separated from the lowest 

 of the others by any markedly greater interval than those otlws are 

 from each other. Involucre flat. Phyllaries with the scarious 

 border broadly fuscous. Radiant florets linear-oblong, blunt, 

 3-toothed at the end, white. Disk yellow. Receptacle (when 

 the florets are all expanded) often twice as long as broad. Fruit 

 with three prominent smooth ribs ; having two internal and nar- 

 row, and one external and broad, rough spaces between the ribs ; 

 the glandular spots round. 



/3. salina ; stem more diffuse often nearly prostrate, leaflets short 

 fleshy, involucre umbilicate, disk broader, fruit with only the one 

 external rough space and oblong glandular spots.

This plant is often very spreading and very fleshy. Its cen- 

 tral upright or ascending stem does not bear nearly so large a 

 proportion to the spreading and usually prostrate branches as is 

 the case in typical M. inodora. In that the branches are usually 

 very short absolutely, or at all events relatively to the upright 

 central stem, and usually, if not always, ascend ; in the variety
