Banks and in the crevices of rocks, in mountainous countries. Fr. 

 July. — The stems have a singular appearance, from the leaves, which be-

 green, not changing their direction when dry. — " The capsule is always 

 crooked." WUs. 



8. B. cdrneum, Linn, (soft-leaved Thread-Moss); stems 

 simple, leaves lanceolate reticulated slightly serrulate at the point, 

 nerve disappearing below the summit, capsule obovate pendulous.

Banks. Fr. April. — Stems rarely exceeding 2—3 lines in length, 

 often bearing innovations, more frequently throwing out sterile shoots 

 from among the roots. The leaves are pale, destitute of the bright green 

 of their congeners, and exhibiting, under a microscope, comparatively 

 large reticulations. 



9. B. albicans, Wahl. (pale-leaved T/t read- Moss); Btems 

 branched, leaves ovate acute the upper ones lanceolate sub- 

 denticulate reticulated the margins plane, nerve disappearing 

 below the summit, capsule pyriform pendulous. Wahl. in

Angus-shire, C. Lyell, Esq. In a ravine, Cam-y-neunt, near Aber, 

 North Wales, Mr. Wilson. Fr. Apr. — This has the capsules of B. tur- 

 binaium, as its discoverer well observes, with leaves more like those of 

 B. carncum : they are, however, considerably broader. Mr. Wilson 

 thought it might be the little-known B. annotinum of Hedw.:— and in- 

 deed its leaves have a considerable similarity in shape to those ot" Bed- 

 wig's figure, (Sp. Muse. U 43.) ; but the capsules are much broader. — 

 This Bpecies has probably been confounded with B. turbinalum and maj 

 not be uncommon. Schwaegrichen*s figure is very characteristic. 



10. B. Ludwigii, Spreng. (Ludwig's Thread-Moss); stems 

 ascending or erect branched with annotinous shoots, Leaves 

 ovate rather obtuse the upper ones lanceolate rather distinctly 



reticulated subserrated concave the margins plane, nerve dis- 

 appearing; below the summit, capsule oblong pendulous. Spreng.

 — It u r ro\\s upon the ground in exposed situations in large compact tufts, 

 an.l has a peculiar aspect, by which it is more easily distinguished than 

 b\ words. The shoots of two, three, or moii- fears rise, one upon the top 

 of another, the upper ones onlj bearing perfect am! green foliage; thej are
