dry and variously twisted at apex, su b falcate secund, convolute-
concave, sparingly serrulate at point, nerve ca rin ate, J width o f base,
vanishing in the apex, cells at base lax, elongate, the angular numerous
thin quadrate y e llow , the upper very small quadrate, smooth at back.
Perich. b ra cts convolute, sheathing, g rad ua lly su b u la te ; caps, on a pale
slender seta, elon ga te, cylindric, olivaceous, stria te, and when dry
remotely sulcate, annulus o f one series o f c e l l s ; lid with a long beak,
oblique, fuscous.
Male pl. more slender, b ra c ts from a broad concav e base, suddenly
acuminate.

Abbey wood and Bostol wood, Kent {Holmes 1874)!! sterile. Recorded also by Taylor
in Fl. hibern. from Glen.fiesk, Kerry.
Turner’s D . fiagellars with fr. from Lough Bray is D. Scottii, and
the barren one from Cromford moor according to Wilson is Campylopus
flexuosus. D.flagellare much resembles the last species but is more robust, the
leaves less curled, with the apex only feebly toothed and smooth at back.
The flagella are usually absent from the lax barren tufts.

Intermediate between D. montanum and Scottii, and remarkable for the
great brittleness of the leaves. D. strictum, S chleich, omd fragilifoUmn, L indb
are also closely allied species. This plant may have been imported attached
to the wood on which it was found, and thus its very limited area accounted
fo r ; It IS scattered sparingly throughout Central Europe from Sweden and
Finland to Italy.
