The sterile flowers of a single perianth of 5 leaves ; and the 
fertile flowers in a lax, membranous cone, of large, concave, entire, 
single-flowered scales ; will distinguish this genus from others in 
the same class and order. 
Only one species known.

t Lupulns is a corruption of the old name, Lupus Salictarius, the Willow- 
wolf, as it was formerly called on account of its growing amongst osiers, to which, 
by twining round, overhearing and choking them, it became as destructive as the wolf 
to the flock. § From the Anglo-Saxon hoppan, to climb.
