ation in the width of the sterile part of the fertile pinnae. The 

 plants described under Blechnum doodioides therefore without 

 doubt represent abnormal forms of 6 1 . Spicant, which Hooker* 

 admits is "the only Lomarioid plant in so northern a latitude"; 

 the general shape, the cutting, and the dark stipes support this 

 supposition. L. crenata Presl (type from Vancouver Island) is 

 described as differing from S. Spicant in being larger, and in 

 having acute, crenate pinnae, the lower ones deflexed and ear- 

 shaped. These characters are found in five sheets from Wash- 

 ington and Oregon (Howell's collections of 1876, 1879, and 1880 

 and in Flett's no. 1928); Flett's collecting note says: "this form 

 is rare and seems to be confined to the largest plants in the 

 dense, mossy woods s " The name L. Spicant, var. serratus Wall, 

 appears on some of these sheets. No further record of this name 

 has been found.

Plants terrestrial. Rhizome creeping and stoloniferous, 15 

 cm. long (in type), slender, 1-2 mm. thick, the scales lanceolate 

 to ovate-lanceolate, 1-4 mm. long, yellowish brown to tobacco 

 brown. Sterile fronds 11-20 cm. long;f stipes clustered, 5 mm. 

 to 4 cm. long, usually slightly angulate, without vestigial pinnae, 

 uniformly castaneous to dark violet or lighter colored in the 

 channel, occasionally with a few ovate-lanceolate to ovate, dull 

 brown deciduous scales; lamina 8-16 cm. long, 17-36 mm. wide, 

 elliptical, gradually reduced at the base (type F) and slightly 

 less so at the apex; pinnae 16-22-jugate, triangular-falcate to 

 oblong-falcate, the apex rounded or obtuse, but often appar- 

 ently acute because of the irregularly revolute margin, the 

 base more or or less dilated, 6-18 mm. long, 4-5 mm. wide; 

 margins entire, irregularly and but slightly revolute; leaf tis- 

 sue herbaceous, roughish in drying, never smooth as in the
