P. urnigerum L. — On dry ditch banks ; frequent. 



P. gracile Dicks. — Peaty bank at 500 feet ; rare in this station. 



P. formosum Hedwig. — Dry banks in wood.

Dicranella heteroraalla Schp. — Clay and peaty banks ; very common. 



*D. Schreberi Schp. — Clay bank near a stream.

C. fragilis B. & S. — Peaty banks ; frequent. 



Dicranum scoparium Hedwig. — Rocks and decayed wood. 



Leucobryum glaucum Schp. — Turfy ground in large masses ; plentiful 

 at 700 feet. 



Fissidens bryoides Hedwig. — Ditch banks ; plentiful. • 



F. taxifolius Hedwig. — Clay banks ; frequent. 



Ptychomitrium polyphyllum Furn. — Rocks at 700 feet ; plentiful. A 

 curious depauperated form is found here with the setae and capsule 

 very unlike the type. 



Tortula muralis Hedwig. — Roadside wall ; common. 



T. subulata Hedwig. — Roadside wall. 



T. laevipila Schwgr. — Trunks of trees and decayed wood. 



Barbula fallax Hedwig. — Peaty and clay banks ; frequent. 



B. convoluta Hedwig. — Clay banks at 700 feet. Var. sardoa B. & S. — 

 Very rare. 



Ulota crispa Brid. — Trunks and branches of trees, frequent from 500 feet 

 upwards. *Var. intermedia Schp. — The trunks and branches of 

 trees up to 700 feet ; rare. This well-marked variety has previously 

 been found in Ireland in Tyrone, Down, Mayo, and Antrim. 



Orthotriclium leiocarpum B. & S. — Lower branches of trees at the extreme 

 ends ; frequent. 



0. Lyellii Hook. & Tayl. — Trunks and branches of Oak at 700 feet. The 

 leaves bristled with adventitious buds, some of which were well 

 developed and branched ; these were known to the old bryologists 

 as Conferva Ovthotrichi. Under favourable conditions they produce 

 young plants with leafy stems, which in their further development 

 may bear either male or female fruit, or revert again to the asexual 

 mode and so carry on the life-history. The plant is rarely found 

 fruiting. It is remarkable that this moss is in America almost always 

 without the brown septate gemmae so characteristic of the British 

 plant. (Plate I., fig. 2a).
