 often apiculate, denticulate above, not curved, more or less 

 densely crowded; alar cells small and well-defined, other cells 

 narrow linear; costa long and double. Perichetial leaves acute, 

 very short-acuminate, generally entire; costa double very long.

 Nos. 351 and 355. 



6. PlAGIOTHECIUM UNDULATUM * P. SUBNECKEROIDEUM. 



Differs in the leaves being less crowded, rather distant, and 

 long-decurrent (as in P. neckeroideum) ; also leaves obtusate, 

 mostly obtuse. Capsules not seen. In P. undulatuni and 

 neckeroideum the leaves are acuminate or at least acute.

 Island, B.C., July 10th, 1908. Coll. John Macoun. 



7. Camptothecium nitens var. microtheca, Kindb. n. var. 



Capsule small. Perichetial leaves hyaline, not filiform- 

 pointed. Stem not or (rarely) sparingly tomentose. Resembles 

 the arctic form "atrichum, Kindb." in not often having a 

 tomentose stem. 



Collected in a bog along Hunker Creek, near Dawson, 

 Yukon, July 27th, 1902. No. 267.

specimens probably belonging to this species, insufficiently 

 described by Lesq. and James, were found near New West- 

 minster, B.C., by Mr. Albert Hill in 1903 and 1904, com. by 

 Messrs. Brotherus and Cufino. This species differs from the 

 others named by me "Myura," in long-decurrent leaves.
