entire ; lobules variable in form on the same branch,
equal to the upper lobe, or half the size, or absent,
subquadrate in form, inflated at the base, upper
border inflexed, and notched at the outer angle, so
as to form a rather blunt tooth. Stipules not
broader than the stem, bifid for half their length,
segments narrow, ■ acute, incurved, sinus lunate,
sometimes they are obsolete, or replaced by
fascicles of very short rootlets, inflorescence
dioicous. Male spikes lateral, composed of few
leaves, the lobes of which are equal. Female shoots
lateral, sessile; involucral leaves larger, lobes ovate-
oblong, and lobules lanceolate. In straggling
patches of a pale yellowish green, sometimes
nearly white.— (Plate i ,jig . 10.)
