 base ; teeth few, remotely scabrous, obtuse or sub-acute tomentose ; 

 branch leaves ovate-lanceolate, sessile, entire, somewhat fascicled in 

 the axils, densely stipitate-glandular, with numerous glandless 

 hairs intermixed, especially on the upper surface, and tipped with 

 an extra long stipe to the terminal apex gland ; the nerves near 

 the margin. 



Involucre hemispherical ; scales in two series, (about eleven in

 stipitate, glandular. 



Rays, five to twelve, broadly cuneiform, deeply three-lobed ;
