Leaves pinnate, with 3 or 4 pair of pinnae ; leaflets ovate, 

 deeply piuuatifid or bipinnatifid ; all the leaves except the upper- 

 most ones (which are bitripinnatifid) stalked, finely pubescent. 

 Anthodes corymbose, radiant. Pericline hemispherical ; phyllaries 

 with a blunt keel on the back, the exterior ones lanceolate, with 

 the margins narrowly-scarious and pale ; the inner ones oblong- 

 strapshaped, white, scarious and lacerated at the summit. Plorets 

 of the ray short, flat, white, but much longer than the pericline. 

 Aclienes cylindrical-prismatic, enlarged upwards, equally 5-ribbed.
