12. D. longirostris ? Web. et Mohr, (long-beahed Didymodon);
stems elongated loosely csespitose, leaves subulatosetaceous
falcato-secund, seta incurved flexuose, capsule oblongocylindrical,
lid rostrate. Fl. Cr. Germ. p. 156, and 463.— Cynodontium
longirostre, Schwaegr. Suppl. v. I. p. 211. t. 29.
Moist shady rocks in alpine situations, but always barren ; as on
Ben-y-Gloe and Cairngorum. Fr. — I introduce this plant with much
hesitation under the above name ; because though the stems and foliage
entirely accord with those of authentic specimens of D. longirostris ; yet
the most important characters depend upon the fructification, which
I have never seen on British individuals.

Dicks.
On the earth, especially in mountainous districts. Fr. Summer.
The reasons for considering the Weissia homomalla, Hedw. to be the
same as our Didym. heteromallus, are given in the Muse. Brit. This
species is remarkable for its crowded mode of growth, yellowish leaves,
pale fruit-stalks, which latter become redder upwards, especially as the
plant advances to maturity.
14. D. pusillus, Hedw. {dwarf Didymodon); stems dender

Bryvui pusillum, Dicks*
"Sandy ground," Mr. Dickson, in E. Bot. Bank (since destroyed)
three miles from Belfast, on the Dublin road; and in the garden of
J. Templeton, Esq. near Belfast, Mr* DrumtncmtL Fr. Spring.— The
short upright rather rigid leaves, with their broad ami lanceolate base,
distinguish the present Bpeciea from the preceding, than which it is
much smaller. NO certain station had been known of thia rare plant,
in Britain, till Mr. Drummond gathered the .specimen^ now lie fore us
in Ireland.
