 On moist banks, especially of rivers ; common. 

 23. Funaria, Schreber. 

 Seta terminal. Peristome, double, oblique : the outer of 16 

 teeth ; the inner of as many cilia, each under a tooth of the 

 outer. Capsule pyriform, its mouth oblique. Calyptra di- 

 midiate inflated below. 



It will be seen by the above characters that Entosthodon very 

 nearly coincides with'the present genus, and that it is not impossible 

 but that at a future time the name of Eng. Bot. Funaria Templetoni 

 may be restored. 



1 . F. hygrometrica, Hedw. Leaves very concave, broadly 

 ovate, apiculated, entire, their nerve excurrent ; seta curved, 

 flexuose. Hedw. Sp. Muse. p. 172. Muse. Brit. ed. 2, p. 121,

Extremely common in a variety of situations, not only in Ireland, 

 but in every visited part of the globe. Hence we should be prepared 

 to expect some variations. Mr. James Drummond sowed the seeds of 

 F. Muhlenbergii, Turn, in a garden pot placed in a frame, using pre- 

 cautions : there came up a few plants resembling this species among 

 more that were intermediate ; but the most of all turned out to be 

 F. hygrometrica. I therefore suppose F. Muhlenbergii is a variety 

 that takes its chaiacter from the limestone soil, on which alone it is 

 found. Mr. Drummond was satisfied that F. hibernica, Hooh. was 

 nothing more. 



24. Zygodon. Hooker and Taylor. 

 Seta terminal. Peristome double, the outer of 16 teeth ap- 

 proached in pairs; the inner of 8 or 16 cilia. Calyptra di- 

 midiate, smooth. 



1. Z. conoideus, Hook, and Taylor. Leaves acute, cilia 8.

On trees ; Orange Grove, near Belfast, Mr. Templeton. Woods 

 at Killarney. The capsule is narrow and striated ; the lid obliquely 

 rostrate. The nerve does not always reach the point of the leaf. An 

 old capsule I observed under the lens in a drop of water, when press- 

 ed, poured out cylindrical, jointed, pellucid bodies, tipped at one end 

 with a brown ball greater in diameter than the cylinder. These were 

 probably seeds in a state of germination. 



24. Orthotrichum, Hoffman. 

 Seta terminal. Peristome mostly double; the outer of 16 teeth 

 approached in pairs ; the inner of 8 or 16 cilia. Calyptra 

 campanulate, sulcate, more or less hirsute.
