Oncophorus, Brid.
Alpine rocks, rare. Ben High, Aberdeenshire, Mr. G. Don. Fr. Aug.
—Were it not for the obscure struma and the narrow recurved margin
of the leaves, I should be inclined to reduce this plant to J), strumiferuia :
indeed I have seen some specimens so intermediate that I have scarcely
known to which I ought to refer them.
13. D. falcdtum, Hedw. (sickle-leaved Fork-Mot*)} stems
nearly simple, leaves long lanceolate-subulate falcato-secnnd
nearly entire, capsule ovate subcernuous Btrumose, lid rostrate.
