wdth a narrow rufescent border o f tw o rows o f narrow cells, bearing for

3— 6, subundulate, in section each o f 4— 5 nearly equal rounded cells.

Catharinea tendía R ö h l , has been recorded as British, but we believe
erroneously, we have seen specimens so-called from the following localities :—
1.— Strensall moor, Yorkshire (Dr. Spruce 1847); referred by Schimper
to C. tenella is certainly only a slender variety of C. undulata g r o A v i n g
in sand, and Mr. Boswell informs me that Schimper afterwards
called it Atr. undulatum Var. tenelliforme ; it may be the same as the
American Var. attennatum of Bry. Eur.
2.— Hell’s mouth, Loch Goil head (Dr. Nichol); also a form of C.
undulata.
3.— Wet places by the road between Ben Lawers and Killin (McKinlay
1865) ; belongs to C. undulata Var. minor.
C. tenella is a good species ; dioicous, having stems i — i in. high ; leaves
oblongo-lanceolate, scarcely undulate, dull green ; capsule oblongo-cylindric,
about half the length of that of C. undulata, inclined, lid large conic, tumid,
rufous, with a nearly straight pale beak rather shorter than capsule.

Dioicous. L e a v e s distant, crisped when dry, oblongo-lanceolate,
sca rce ly undulated, smooth at b a ck ; lamellæ i — 3, v ery narrow.
Capsule oblong, suberect ; lid conic, shortly rostrate. (T. V , C.)

Dioicous ; in soft lurid-green tufts. Stems ta ll, slender, simple,
with very distant leaves, rooting only at base, 2— 4 in. high. Le a v e s

pairs ; nerve thick, vanishing in the apex, sometimes with a few spines
at back, lamellæ very low and indistinct, i — 3, in section showing a
row o f I— 3 rather lax rounded cells ; areolation lax, th e basal cells
rectangular, hyaline, empty, the rest irregular, rounded and hexagonal,
chlorophyllose ; perichætial bracts larger and more acute. Pedicels
slender, 1— 3 in each perichætium, capsule suberect, often a little curved,
oblong-obconic, wide-mouthed, brown ; lid conic with a subulate beak,
calyptra scabrous at apex ; peristome with sca rcely any basal membrane,
