Paraphylla are present in this species, which completely cover the 
stem between the leaves with a short felt. The largest are leaflike, 
though many times smaller than the true leaves, lanceolate or lan- 
ceolato-subulate, entire or with one or two teeth near the base. In 
their more rudimentary form they simulate radicles, being one or 
more cellules in breadth and slightly and irregularly branched. 
Hence the species may be considered to have some affinity with 
H., filicinum on the one hand, and with H. Pyrenaicum on the other.
