(952.) P. decursivifolium, Kindb. (Q. sp.) 



Hypnum latebricola, Canadian Musci, No. 304, in part. 



Intermediate between P. latebricola and P. pseudo-latebricola. Agrees 

 with the last in the branches being complanate, the leaves distichous, 

 the capsule oblique ; differs in the leaves being broader, short-pointed, 

 decurrent, the alar cells not distinct but the decurrent ones rectangu- 

 lar, the capsule in a dry state arcuate and finally furrowed, the lid 

 longer often curved. 



On cedar (Thuya occidentalis) stumps in a swamp, 5 miles west of 

 Belleville, Ont. The specimens (fruiting) were named P. Passaicense 

 by Austin, and probably distributed under that name by him.
