inches long stout stramineous black at the swollen base 

 clothed especially in the lower half with long flexuous ferru- 

 ginous subulate scales, frond a span long rigid-coriaceous 

 deltoid acute bipinnate, pinnee opposite horizontal sessile 

 moderately distant uppermost ones confluent 2-3 inches long 

 ovato-lanceolate, pinnules approximate ^-J of an inch long 

 broad-lanceolate subcuneate at the sessile base acute pin- 

 natifid apex^ entire superior base auricled, segments ovato- 

 oblorig acute slightly falcate, veins pinnate forked once or 

 twice, sori near the costa copious one to each lobe (2 or 3 in 

 the auricle and lower lobes, involucres (young) rotundato- 

 reniform pale brown meml)ranaceous eroso-fimbriate at the 

 margin, rachises slightly winged above from the decurrent 

 bases of the pinnules more or less villous with tawny hair- 

 hke deciduous scales. — Hook. Ic. PL t. 43. Aspidium me-

Hah. Tristan d'Acunha, on the table-land, Dr. Carmichael. — A very distinct 

 and very rare species, only I believe found in the island just mentioned. " Stem 

 (caudex) about 6 inches high, crowned with a circle of fronds from 9-12 inches 

 high."

 frond ovate bipinnate, pinnee subopposite subsessile linear- 

 oblong narrow-acuminate, pinnules sessile obtuse pinnatifid 

 lowest ones ovate superior oblong-lanceolate, segments obo- 

 vate inciso-dentate, secondary rachis winged, sori incurved."

Hab. Chili, Cuming, according to Presl, and repeated by Sturm ; but no one 

 else recognizes such a species from that country. 



235. A. (Athyrium) grammitoides. Hook. ; caudex creep- 

 ing densely rooting, stipites approximate 3-4 inches long 

 copiously scaly, fronds 4-10 inches long lanceolate-acumi- 

 nate firm-membranaceous subhispidulous pinnate pinnatifid 

 at the apex, pinnae H inch long patent approximate lanceo- 

 late subfalcate obtuse superior base auricled all lobato- or 

 dentato-pinnatifid especially towards the base subpetiolate, 

 sori large in two rows oblong, involucres slightly curved mo- 

 derately convex strongly ciliated, inferior ones often dipla- 

 zioid, main rachis slightly winged upwards. — Hook. Ic. PL
