to those of the stem, smaller, cuspidate-acuminate, rotundate-cuneate on 

 the inner side at the base, with the cusp 'A— Vs as long as the blade. 

 Spikes square, to I'A cm. long, I'A mm. diam. ; sporophylla ascending, 

 ovate-oblong, acute or acuminate, minutely denticulate, keeled ; macrospores 

 white or pale-yellow, 1 — 2 in a macrosporangium, irregularly rugulose 

 with short or elongated, flexuose, branched or reticulated ridges, the 

 apex flattened, without radiating ribs, encircled by a crown-shaped ring; 

 microspores probably wanting. — In order to avoid confusion the name 

 S. Grabowskyi Warb. is maintained, though I acknowledge that the 

 name S. intermedia Hieron. has a legitimate claim on priority.

Near S. Q-rabowskyi Warb. — Shoots to 30 cm. long; stem or msiin 

 rachis 6 — 9 mm. broad including the lateral leaves; pinnulae simple, 

 forked or pinnate; ultimate branchlets 4 — 6 mm. broad; lateral leaves 

 proportionally longer, more distinctly pellucid-margined on the upper side, 

 less conspicuously spuriously veined, the upper edge denticulate throughout

 longer. 



Forma typica: Relatively small plants; lateral leaves of the main 

 stem less falcate than those of the branchlets, often bluntish. — Sumatra. 



\ar. subbinervia: Middle-sized plants; lateral leaves of the main
