249. 1899. 
Blechnum lineatum C. Chr. Ind. Fil. 156. 1905. 
Plants terrestrial. Rhizome erect, 10 cm. high (see discussion 
following this description), 3-5 cm. thick, the scales 1-2 cm. long, 
-6 mm. wide, burnt umber to tobacco brown. Sterile fronds 
40-155 cm. long; stipes clustered, 18-90 cm. long, angulate, 
shining or dull, light-colored, or less often ‘bicolored (with brown) 
or more rarely blotched with brown (purplish brown in some 
Cuban specimens), the scales numerous, brownish yellow, mixed 
with more or less fibrillose ones, very loosely appressed, at least 
toward the rhizome, more numerous than in S. striata, the attach- 
ment of the larger ones indicated by dark points or raised dots; 
lamina 28-74 cm. long, 8.5-36 cm. wide, oblong to narrowly 
lanceolate, slightly or not reduced at the base (type A, without 
vestigial pinnae), gradually reduced at the apex, the pinnae close 
to overlapping in the smaller plants; pinnae 18-40-jugate (usually 
20-40), linear-oblong, falcate, the apex acuminate, serrate, the 
cordate, often partly covering the rachis, often free through- 
cut, the lowest pinnae petioled, 6.5-20 cm. long,* 0.9-2 cm. wide; 
margins subentire, somewhat cartilaginous, rarely revolute;f leaf 
tssue herbaceous to rigid-herbaceous, usually somewhat shining be- 
low, the costal scales smaller, usually numerous, tan, fawn, and buff, 
rarely araneous; veins rarely raised below, the vein spaces 13-18 to 
Icm. Sporophyls 92-146 cm. long; stipes 43-85 cm. long (one 
Specimen has a chestnut cast, otherwise like the sterile); lamina 
28-66 cm. long, slightly or not reduced at the base, somewhat re- 
duced at the apex; pinnae 24-40-jugate, 8-18 cm. long, 3-4 mm. 
wide, with a sterile tip 5-10 mm. long, petioled, the lower bases 
Tounded or cordate; sporangia very dark brown; indusium irregu- 
larly lacerate.
