Not rare on rocks amongst other mosses in oak woods near 

 Victoria, Vancouver Island. Collected in May 1875, and named 

 B. ruralis var. gigantea by Austin. No mention of this form is 

 made by Lesquereux and James. The specimens upon which the 

 species is founded were collected April 21, 1887, by John 



Macoun. 



Grimmia arcuatifolia, Kindberg. 



Loosely tufted ; tufts blackish, dark green above. Stems 5 

 cm. long, denudate at base. Lower leaves small, upper long 

 and not crisped ; hooked-recurved when moist, ovate-lanceolate, 

 long-acuminate and acute, reflexed at least at one border with a 

 short denticulate hair-point ; the most basal cells pellucid, long and 

 narrow, the upper basal cells sinuous, the marginal uniseriate 

 and hyaline or not distinct ; other cells chlorophyllous, quadrate 

 and not sinuous ; costa percurrent canaliculate, pellucid m the 

 middle. Probably allied' to the European Grimmia elatior, 

 Bryol. Eu., but this species has also the upper cells sinuous. 



Abundant on dry rocks at Cedar Hill, near Victoria, Van- 

 couver Island. April 21, 1887. John Macoun.

Scouleria aqnatica, Hook. {Grimmia Scoulcrt C. Mull. 

 Lesq. & James Manual.) This genus (Scouleria) is more nearly 

 allied to Cinclidotus than to Grimmia. The plant occurs in two 

 forms, possibly proper species, my specimens are not fruiting.
