—Bantry, South of Ireland, Miss Hutchins (Herb.
Mitten).
The only known station.
O b s .—Mr. Mitten detected this fine species in a collection
made many years ago by the late Miss Hutchins in the South of
Ireland. I t is abundantly distinct from either P. punctata, Tayl.
or P. spinulosa (Dicks.), with which it is nearest allied.
I am indebted to Mr. Mitten’s description for most of my
notes of the species.

Dioicous, cæspitose or creeping amongst mosses, medium to
largish size, of a pale yellow, yellowish-green, or olive-brown
colour. Stems erect or creeping, simple or dichotomously
branched ; radiculose almost up to apex of stem, rootlets whitish,
branohes lateral, subpostical, arising from axil of leaves or bracts.
Leaves patent at an angle of 40° to 60°, alternate, distant or contiguous,

ovate, with few large teeth or spines on the upper margin, lower
margin entire, reflexed; texture somewhat firm, cells smallish,
roundish ; walls rather thick, angles thickened, trigones wanting.
Stipules rudimentary, minute, bifid or trifid, or wanting. Bracts
larger than the leaves, with numerous teeth on the upper margin,
broadly ovate. Bracteole wanting. Perianth broadly obovate,
compressed, mouth wide, ciliate-dentate; pistillidia numerous.
Male stems distinct, more slender and graceful, perigonial bracts
at the middle or end of the stem, oatkiii-like, small, closely imbrioate,
about 5 pairs, broadly oval, lobulate, lobule 2-3 dentate;
