This is a very large and distinct species. All the green parts are bearded with remarkably long and dense hairs ; 
the underside of the leaves is very hoary, silvery, and soft. “The flowers are large, and of a pale yellow colour, with 
a tinge of pink within; they are collected in short, peduncled, axillary, solitary fascicles, surrounded by a number of 
narrow, very long, curved, fleshy, green bracts, which are thickly beset on the outside and margins with very long 
spreading hairs; two or three of these bracts issue sideways below each calyx or pedicel, forming collectively a large 
and wide involucre, the points of which converge slightly over the flowers.
