ore inagno, operculo conico acuminato, peristomio interno processibus 

 solidis ciliis binis aequilongis in merabrana fere ad dentium medium 

 exserta. 

 Hab. Canaries, ex Herb. Webb.; Teneriffe, Bouryeau, in Herb. Hook.; 

 Madeira, Johnson; Ireland, on Turk Mountain, 1829, Wilson. 



Nearly resembling 8. cupressiformis, Brid., in the state called 

 " mammillatus" but differing from all states of that variable moss 

 in the sharp serrulation of its leaves and in the size of the cells 

 — about half as long and nearly twice as wide. In some speci- 

 mens the capsule is very short — not longer than wide.

(JHiynchostegium, Schimp.) 



H. surrectum, sp. nov. Monoicum, caule repente radicante ramis 

 pluribus brevibus pinnatim ramoso, foliis patentibus sursum curvatis 

 surrectis nitidis e basi ovata longe subulato-lanceolatis, nervo medio 

 evanido, marginibus integerrimis in ramulorum apicibus serrulatis, 

 cellulis basi paucis majoribus latioribus superioribus elongatis augus- 

 tis, perichsetialibus subsecundis ovatis subulato-aeuminatis subserru- 

 latis nervo brevi, theca in pedunculo brevi lsevi ovali horizontali, oper- 

 culo subulato longirostrato, peristomio interno processibus perforatis, 

 ciliis duobus dimidio brevioribus, in membrana fere ad dentium me-

Hab. Madeira, on stones, Johnson. 



A shining green moss, in size resembling H. confertvm, Dicks., 

 and in the form of its leaves intermediate between it and H. tenel- 

 lum, Dicks. It is remarkable for having all its leaves curved 

 upwards in the same way as those of H. resupinatum, "Wils. 



(Amblystegium, Schimp.) 



H. Maderense, sp. nov. Monoicum, caule repente latissime caespi- 

 toso pinnatim ramoso, foliis patenti-divergentibus e basi subovata 

 sensim subulato-lanceolatis, nervo percurrente, marginibus integerri- 

 mis subserrulatisve cellulis oblongo-ellipticis, perichaetialibus erectis 

 convolutis ovato-lanceolatis obtusatis nervo excurrente mucronatis 

 plicatis, theca in pedunculo gracili rubro longissimo arcuata cylin-

Hab. Madeira, on rocks and the earth, Johnson, and Milne in Herb. 

 Hook. ; Canaries, Montagne. 



This fine species has the habit and appearance of H. serpens, 

 Linn., but is in all its parts far larger and more rigid. It grows 

 in extensive patches of a fresh green or, sometimes, brownish
