The Filix-Mas grou}). 
17. Lastrea patentissima. (Presl. ;) Caudex short, stout, erect, densely paleaceous with broad-lanceolate scales varying much in 
colour, stipites short, copiously scaly, rachis densely clothed with long subulate tawny or golden scales : fronds very large, pinnate 14-16 
inches broad ; pinnae patent, deeply almost to the partial rachis pinnatifid, segments very close and compact, oblong-parallelogram more 
or less sharply toothed towards the apex, margins ciliated, partial rachis and costa more or less scaly below, nearly glabrous above, sori in 
2 rows, one on each side of the costa of the segments, situated on the centre of the superior veinlet, indusium reniform — Nephrodium

18. Lastrea elongata. (Swartz ;) Caudex short, stout, erect, paleaceous, stipe and rachis more or less scaly, or nearly quite 
glabrous, fronds large, very broadly ovate, bi-pinnate with the lower portions often tri-pinnate, partial rachis more or less scaly, pinniiles 
glabrous, segments more or less deep, obtusely rounded, crenated ; sori generally one to each segment on the centre of the superior veinlet, 
indusium very large (as in L. Cochleata, but the frond is not contracted as in that species). — Aspidium marginatum, Wall. Cat. n. 391 ; —

19. Lastrea intermedia. (Beddome ;) Caudex short, erect, paleaceous, stipe short scaly ; fronds pinnate, ovato-lanceolate, 6-lo 
inches long, 3-4 inches broad, pinnoe distant, short ovate to broad lanceolate, pinnatifid more or less deeply, (but not pinnated) segments 
broad, obtusely rounded, glabrous — sori very large, reniform, irregularly placed. 
This small ]nmiate species seems a very distant variety of the Filix-mas group, it has the very large involucres of cochleata, but 
it seeds on all its fronds, and tliey are never contracted, or very slightly so — it is intermediate between the next species and cochleata. 
Nilgiris — near Malee Mand. — Anamallays 5,000 feet. 
PLATE No. CXIIL 
20. Lastrea odontohma. (Moore ;) Caudex short, erect, densely paleaceous, stipes and rachis more or less densely covered 
with golden, or tawny scales, fronds lanceolate, pinnate, with the lower pinnae again pinnated (hence bi-pinnate below) partial rachis scaly, 
pinnae narrow, lanceolate to linear-lanceolate, pinnules more or less sharply toothed (sometimes with very long sharp teeth at the apex) 
often lobed at the base, sori reniform small, in a nearly regular row on each side of the flexuose costa of the pinnules. 
Nilgiris — Anamallays — above 5,000 feet. 
PLATE No. CXIV. 
21. Lastrea cochleata. (Moore ;) Caudex stout, erect, paleaceous, stipes and rachis scaly, or often quite glabrous, fronds 1^ to 
3 feet long, broad ovate-lanceolate, pinnate with the pinnae pinnatifid to nearly the base, pinnules incised with sharp teeth on the lobes 
below the serratures ; fertile fronds contracted, lower pinnae again pinnated, upper ones pinnatifid, sori very large, closely packed and 
perfectly covering the under-surface of the fronds. Nephrodium (Lastrea) Filix-mas, var. 5. Cochleata, Hook. Sp.Fil.iv. 117 ;— Ne-
