elliptic-lanceolate, acute, 3-1} in. long, 6 lin. broad, minutely hairy 
above, shining white-silky beneath. Flowers in dense globose heads 
on long peduncles. Sepals narrow and ciliate, just like the bracts.

Very near J. crepidiformis, Hallier f., but, according to the author, easily 
distinguished by its lower dense growth, elliptic leaves with their silvery under- 
surface and smail flowers. It it evidently very near to the var. minor, but differs 
in its much broader leaves.
