safely separable from nigripes. In some of them the frond is nar- 

 rowed gradually to the base ; and in others the lowest pinnce are 

 as long as the central ones. There is a small form with tlie 

 lamina not more than half a foot long, and yet copiously soriferous, 

 and another with ultimate segments regularly, closely, and sharply 

 iucised to a depth of a line or more. 



220*. AsPLENirM (DiPLAziu^j) BREViPEs, BciJcer^ n. sp. Stipe 

 (incomplete) slender, green, naked, like the rachis. Frond oblong- 

 lanceolate, membranous, glabrous, simply pinnate, 6-8 in. loug,

Pinnae 



lanceolate, 10-12-jugate below the pinnatifid apex, the upper ones 

 sessile, the lower distinctly petioled, the largest 12-15 lines long, 

 I in. broad, obtuse, cuneate-truncat^ on the lower side at tlie base, 

 produced on the anterior side and imbricated over the rachis, with 



shallow oblong lobes

down to the midrib. Veins pinnate opposite the lobes of the 

 pinnae, with 2-3-jugate ascending distinct veinlets. Sori usually 

 one to each group on the lowest anterior fork, beginning at the 

 base, but not reaching the tip, only few diplazioid. Involucre 

 narrow, glabrous, persistent.

 Stipe (incomplete) naked, browniah. Frond oblong-lanceolate, 

 bipinnatifid, 15-18 in. long, 4-6 in. broad, not narrowed at the 

 base, moderately firm in texture, pale green and finely pilose 

 beneath, dark green and glabrous beyond the midrib above, 

 copiously marked with white dots on the margin; rachis brown, 

 finely pubescent. Pinnae lanceolate, only the lowest minutely

Veins in pinnate groups opposite the lobes of the pinna?, with 

 4-6-jugate distinct erect o-patent veinlets, the lowest pair ceasing 

 before they reach the edge and bearing each a sorus at the tip. 

 Sori on the other veins median. Involucre brow^n, glabrous, per- 

 sistent, \ line broad. 



Allied to N, sulliauritum siui j)unctulatum^ which, like iT. albo- 

 puncfafum, show the same copious white dots on the edge of the 

 lobes of the pinnae.
