Hal). "Cuba, 184.3-4, Zmr/e«, n. 1901." — A very distinct and -well-marked 

 species, in its ample scaly clothing somewhat resembling A'. Raddianum ; but in 

 other respects very different, especially in the nature of tlie scales, which in Rad- 

 dianum give an untidy look to the plant, as if injured by parasitic insects. 



73. N. (Ldistvea) pi/osulurn, Hook.; "caudex erect, fronds 

 2 feet long membranaceous and together with the stipes soft 

 villoso-pilose lanceolate pinnated, pinnae shortly petiolate 

 2-3 inches long from a truncated base linear-lanceolate 

 acuminate pinnatifid, segments oblong straight or subfalcate 

 obtuse entire or repandly crenate, the basal ones generally 

 larger, sori large near the margin of the segments, involucres 

 conspicuous roundish reniform membi-anaceous ciliated at 

 the margin at length deciduous." Metten. — x\spidium, Kl.

Hah. CoXnmbia, " Morilz, n. 114, and Venezuela, Wayener," Fendler, n. 178, 

 j3. — My only specimen of this is from Fendler (not 178, which is N. conterminum), 

 and the only allusion I can find to its aiSnity is in Mettenius, " Trunco erecto con- 

 gruit cum A. oligocarpo, soris majoribus indnsioque manifeste diversum." Is it 

 really distinct ixom A. patens ? 



74. N. (Lastrea) Kunzeanum, Hook. ; " frond broad-lan- 

 ceolate truncated at the base pinnated, pinna? subsessile li- 

 near-lanceolate acuvninate pinnatind with the margined rachis 

 and elevated veins hairy beneath, segments lanceolate falcate 

 acute repando-marginate ciliated, lowest ones dwarfed (deor- 

 sum subdeficientibus) pellucid at the sinuses, rachis and 

 stipes tetragonous pubescent, sori submarginal, involucres 

 Jiairy." — Aspidium, Kze. in Linntsa, ix. p. 93. Metten. Aspid.

Hal). Pampayaca, Peru, Papjng. — Neither the specific character, nor my au- 

 thentic specimen from Kunze, seems to offer any difference from my equally 

 authentic specimens of N. macrourum. 



75. N. (Lastrea) falciculatum, Desv. ; caudex stout erect 

 thickly clothed with subulate scales, stipites a span long de- 

 ciduously scaly, rachis slender ferrugineo-puljescent, frond 

 from a broad base ovato-oblong 12-14 inches long membra- 

 naceous flaccid pubescenti-glandulose viscid especially be-
