RECENT ADDITIONS TO OUR MOSS FLORA. 227 



orifice scarcely appearing above the tips of the perichsetial leaves, thin 

 walled, pale and pellucid, shortly pyriform; teeth of peristome short; 

 beak of operculum very short, scarcely oblique. /8. longifolla ; plants 

 larger ; capsule considerably exserted ; beak longer and more oblique. 

 — Buxton, Derbyshire, collected by Mr. Wilson in 1831. In a com- 

 munication to the Linnean Society (.Jan. 20th, 1870, which will be 

 printed in the next number of that Society's Journal), Professor Lind- 

 berg thus characterizes a new Seligeria, having leaves like those of 

 paucifolia, but in fruit resembling 8. jmsilla. The typical form is 

 Scandinavian, and the variety /S only has been found in this country. 



1. Dicranella fallax, "Wilson, ms. (Plate CIX. fig. 2.)— Dioicous, 

 closely resembling D. varia. Leaves more distant, with impressed 

 wings and less elongated setaceous points, and a more dilated, flat- 

 tened nerve, uppermost subsecund. Capsule nearly symmetric, erect 

 or subcernuous, with a shorter conical lid. — Banks. Fruiting in March 

 and April. Anglesea (Wilson). Cotterali Wood (Mr. Hunt). Park- 

 gate, Cheshire (Miss Jelly). 



2. D. cMrm^a, Schimper, Syn. Muse. Eiu*. p. 75. Dicranum curvatum, 

 Hedwig, Spec. Muse. p. 132. — Resembling D. subulata. Stems short, 

 bi- or tripartite. Leaves less elongated, with a shorter base, falcato- 

 setaceous, obsoletely denticulate at apex; the perichsetial scarcely sheath- 

 ing, diaphanous. Capsule on a brown peduncle, erect or a little 

 curved, ovate-oblong, equal, more distinctly striated ; lid with a 

 broader base and a shorter, less curved beak. — Sandy banks. Llanberis 

 (Wilson). 



3. D. heteromalla, Seh., var. sericea, Sch. Syn. Muse. Eur. p. 76. 

 Dicranodontium sericeum, Schimper, Muse. Eur. Novi, fasc. 1. — Plants 

 taller. Leaves diverging almost on all sides, pale green or yellowish, 

 often strongly and remotely toothefl ; entirely according with the typical 

 form in structure. Fruit has been found in the Riesengebirge by 

 Wichura ; the capsules being ratlier long, and at last almost erect. — 

 Soccoth Hill, Arrochar (M'Kinlay). 



DitricJiim, Timm. — This genus was established on D. pusillum, by 

 Timm, in 1788, in his 'Florre Megapolitanre Prodromus' (p. 216), which 

 thus has four years' priority of Hedwig's Didyynodon pusillus, and eight 

 years over Schrader's Trichostomum tortile, of which it has l)een iui- 

 properly made a variety instead of standing as the type ; Hampe in the 

 * Regensburg Flora,' 1867, therefore witlidraws his genus Leptotrichum,
