Monoicous, cladocarpous and acrocarpous, small,
pallid, very tender, prostrate, stem rising from a
rhizomatose base, almost leafless, and sparingly
branched. Leaves distant, only at the apices o f the
fertile branches somewhat imbricate, oval, deeply
and acutely bilobate, lobes broadly subulate, acuminate,
incurved, one or other armed with a tooth ;
cells small, subquadrate, pellucid. Stipules minute,

none. Male catkins terminal on the stem, or
occupying nearly the whole branch. Bracts narrow,
often denticulate, lobes acuminate, upwards secund.
Female branch short or elongated, often innovantly
