lected from bogs in the North of Ireland twenty years ago; and Mr. 
D. Orr has it from the Three-Koek Mountain, Co. Dublin, and also from 
Howth, as well as the variety 7 . oihesum from the latter place. 
Grimmia Schultzii (Bridel ). Schultz’s Grimmia. 
Habitat: on granite rocks near the Scalp, Co. Dublin, July, 1854; 
Mr. D. Orr. This plant we had for some years considered to be only 
Grimmia tricophylla , to which species it bears strong resemblance; but 
some doubt having arisen on the matter, specimens were submitted to 
Mr. "Wilson, who at once pronounced it his G. Schultzii. 
Orthotrichum Lyellii (Hooker). Mr. Lyell’s Bristle Moss. 
Habitat: on trees near Clonmel, and at Powerscourt. This in¬ 
teresting addition to our Plora was first discovered by me growing on 
trees by the side of the River Suir, near Clonmel, bearing fruit in July, 
1856, and since barren at Powerscourt. 
Bryum warneum (Blandow ). Warren Thread-Moss. 
Habitat: on muddy spots at the North BuU, near Dublin, 1857; 
Mr. D. Orr. This species is described at page 12, “Bryologia Britan- 
nica,” among the addenda. At the time of the publication of that work 
only two habitats appear to have been known for this moss in Britain; 
one in Pifeshire, Scotland, and the other in Lancashire; the discovery 
of it in Ireland is, therefore, the more interesting. 
Bryum inclinatum (Br. and Sch.). Small-mouthed Thread-Moss. 
Habitat: this species came up in considerable quantities among 
heath mould brought from the Dublin Mountains, in one of the conser¬ 
vatories at the Botanic Garden in 1856, and has since been collected on 
a wall at Howth, by Mr. D.Orr. Probably not rare. 
Bryum cernuum (Hed/w.). Drooping Thread-Moss. 
Habitat: on the waU which surrounds the viceregal demesne, 
Phoenix Park, 1856; Mr. D. Orr. And since, in other localities near 
Dublin. 
Hypnum salebrosum (Hoffman). Smooth-stalked Streaky Leather Moss. 
Habitat: on a grassy sand-bank by the side of the River Tolka, near 
the Botanic Garden, Glasnevin, 1857 ; Mr. D. Orr. 
The following species have either been considered of rare occurrence 
in Ireland, or have had no certain localities mentioned in “ Bryologia 
Britannica”:— 
Sphagnum rubellum ( Wilson). Red Dwarf Bog Moss. 
Habitat: near the base of Carntuel Mountain, Killarney, June, 1857, 
growing with Jungermannia Woodsii and J. juniperina.
