reproductive organs are more fasciculate. The cystocarps too, in 

 the next species, are cah^arate, while those of 0. Lj/allii are ecal- 

 carate. We have found old and complete specimens of (). Lyallii 

 with a thickened stipe-like portion below, but even here, there is 

 little midrib and the upper portion is entirely plane. Miss 

 Tilden's specimen from San Juan Island pro])al)ly belongs to this 

 species, but may perhaps, judging from its color, more properly 

 be placed iinder the next. Certainly it has nothing in common 

 with Ldio'f'iiria (irevilleand under which she has placed it..

We have quoted the various published mentions of the occur- 

 rence of this species within our territory and have added two 

 localities whence we have examined s])ecimens. We feel much 

 doubt in referring the specimens to this species; one is a sterile 

 plant and, while the other has stichidia, the chief differences 

 between them and the specimens from Whidbey Island, which we 

 refer fairly confidently to the preceding species, is in the color 

 (these being a dark red and those being a light brownish tint) and 

 a tendency on the part of the specimens we refer to the present 

 species to have a fairly prominent midril) in the lower portion of 

 the frond. The figure of 0. (vngusiifolia Postels and Ruprecht 

 (1840, ])1. 27). which Ruprecht says is of this species and not of 

 0. angustifolia Suhr, shows a sterile plant with a distinct midrib 

 to very near the tips of the branches.
