Found on the Continent (Norway), in Cuba, and South
America.
Obs.—A distinct species and the only British example of the
.genus. When in fruit the postical $ and ? would readily identify
it, but $ has only been sparingly found by Dr. Carrington in
Ireland, and no perianths have yet been discovered on British
specimens. When barren, distinguished from Plagioehüa punctata
iayl., which it resembles someivhat in size and habit, by its dark
lurid green colour, leaves usually unispinose, antical margin
incurved, and the large hexagonal cells.
The description is taken from Dr. Spruce’s valuable notes in
“ Journ. of B o t” (1876).

Plants usually robust, some large, others rather small, olive-
green, reddish-brown or purple, grovving in matted tufts or in
large masses in streams. Stems firm ; primary shoots creeping,
perennial, naked, rhizomatous, entangled ; secondary shoots foliose,
ascending, decurved at the apex, simple or dichotomously branched;
branches all exactly axillary to the leaves. Leaves disticho-
declinate, alternate, conduplicate, unequally bilobed; postical
lobe larger, convex; antioal lobe incumbent; margins entire,
dentate or ciliate. Stipules absent. Infloresoenoe dioicous, rarely
paroicous, terminal. Bracts 2, free, resembling the leaves but
more equally lobed. Perianth much longer than the bracts,
frontally compressed, plane, not winged, mouth wide, truncate,
bilabiate, entire or dentate, decurved. Calyptra free, included.
Capsule ovate, of thick texture, divided to the base into 4 equal
valves. Elaters attached to the centre of the valves, long, bispiral.
Androecia terminal or interrupted. Perigonial bracts smaller,
ventricose at the base, the lobes shorter and nearly equal.
Antheridia (3 -1 2 ) axillary, oval, seated on a slender stipe.
