\\5. Leskea complanata, Hedw. (Hypnum complanatum. Muse.

 tions. In Teesdale this elegant moss is almost constantly associated

 The capsules had passed the season of maturity, and were therefore 

 in an unfit state for observing the eilia ; but by attentively watching 

 this moss on a wall near Castle-Howard during the last three sum- 

 mers, I have satisfied myself that well- developed capsules usually 

 possess an inner peristome. I have arrived at the same conclusion 

 respecting 0. cupulatum; but in the latter the cilia are 16, in the 

 former only 8. 



129. — crispum, Hedw. On trees, with 0. Drummondii. 



130. — cupulatum, Hofliin. In the same localities as O. anomalum. 



131. — diaphanum, Schrad. Trees and walls, between Barnard 

 Castle and Middleton. 



132. — Drummondii, Hook. This beautiful species is more abun- 

 dant in Upper Teesdale than any other of the genus, and may be met 

 with everywhere on shrubs and young trees. I observed it in the 



T2
