position of the fallen ones marked by points as in S. lineata; 
lamina 22-71 cm. long, 12-35 cm. wide, broadly lanceolate to 
broadly oblong (broadly ovate or elliptical in the smaller plants), 
not at all or slightly reduced at the base (type A, without vestigial 
pinnae), usually reduced gradually at the apex, not reduced in the 
smaller forms; pinnae 7—20-jugate, lanceolate to lance-oblong, 
straight or slightly curved in the outer half or near their apex 
(falcate in some of the smaller fronds only), 8-20 cm. long, 1.8-3 
cm. wide, tapering gradually, if slightly, to the abruptly acuminate, 
serrate apex, the lower pinnae petioled, the base decidedly cordate; 
margins revolute; leaf tissue rigid-herbaceous to coriaceous,* the 
costae scaly, fibrillose, or naked, the under surface delicately 
but often fully araneous on the raised veins; veins distinct, 
definitely raised below, the vein spaces 12-16 to I cm. Sporophyls 
40-175 cm. long; stipes 24-118 cm. long; lamina 48-64 cm. long 
(16-23 in the smaller forms), reduced at the apex, but slightly 
reduced at the base; pinnae 15-27-jugate (7-15 in the smaller 
forms) with a sterile tip 5-10 mm. long which is often serrate, the 
lower petioled and cordate at the base,'7-18 cm. long, 3-6 mm. 
wide; often whitish-knobbed at the vein ends as in 5. vivipara; 
sporangia yellowish brown to dark brown; indusium irregularly 
lacerate, often to the base.
