266 Mosses to be Found in May. 



not as long as the leaves, only abont two lines in length, curved, 

 and seeming to be lateral, in consequence of the growth of 

 innovations, which are usually solitary; but the flowers, when 

 examined at an early stage, are always found to be truly 

 terminal. The moss is an inhabitant of alpine and sub-alpine 

 rocks, and fruits in June and July, sometimes bearing two or 

 three capsules together. 



Bartramia arcuata, or the curve-stalked apple-moss, 

 strikes us, at first sight, as an exaggeration of B. Halleriana, 

 with red fruit-stalks, which, though longer, are still short and 

 arcuate, being only about twice or thrice the length of the 

 capsule, which hangs sub-pendulous upon it, and, as in Halleri- 

 ana, have the appearance of being lateral from the same cause, 

 namely, the growth of innovations. It, too, grows in extensive'' 

 yellowish-green patches, bat the stems reach from two to four 

 inches in height, densely covered with reddish-brown radicles, 

 and the leaves, which are plicated, are of an ovate-lanceolate 

 form, shining, sheathing and erect at the base, thence widely 

 spreading, with a nearly plain serrulate margin, and an excur- 

 rent or sub-excurrent nerve. It grows on moist heaths and 

 on the rocky banks of streams in hilly places, forming dense 

 masses ; and though its rich golden globular capsules are 

 rarely met with, its bright yellow-green foliage contrasts 

 agreeably with the downy fuscous radicles that so thickly 

 clothe the lower part of the stem, and this contrast renders it 

 a most attractive object even in the barren state. Its fruiting 

 season is September and October, two or three months later 

 than B. Halleriana, and it may be met with on the Sidlaw 

 Hills, above the village of Auchterhouse, in fruit;- it is also 

 said to be abundant at Lodore Waterfall, near Keswick, and in 

 fructification at Lidford Fall in Devonshire, and at Cromaglonn, 

 near Killarney, Ireland; also sparingly in fruit near Llyn 

 Ogwen in Carnarvonshire. 



Another species, Bartramia cCBspitosa, hitherto considered 

 Swedish, lias lately been found by Mr. Wilson, in a new marsh 

 near Warrington ; but not having seen a specimen, we are 

 unable to describe it. 



l!(irlrtini!<liihi Wilsonii, or the beardless dwarf applc-vioss, 

 is amost beautiful Little plant, somewhat resembling Bartramia 

 fontama in miniature, but its exquisite little pink capsules are 

 sub-pendulous or quite pendulous, and hang on reddish arcuate 

 fruit-stalks, often three or four together, and resembling full 

 short pears rather than apples in outline, are smooth, shining 

 when dry, with thin, somewhat pellucid walls, which are of soft 

 texture, slightly rugose in the dry state, but not striated, and 

 having a small mouth destitute of peristome, and closed with a 

 small sub-conical lid, which is again surmounted by a small,
