bearing scaly bulbils from which new shoots spring. Piniise with bluntly lobed or 

 crenate margins, sometimes deeply lobed at base, base truncate, rhachis and imder- 

 side of pinnae glabrous or sUghtly pubescent. 



This is the only .species of Goniopteris retained by Beddome in that genus. Baker 

 and Hooker keep* it in Polypodium where it was placed by Roxburgh. Although the 

 habit and the sori are somewhat different from most of Nejphrodium they seem to 

 me insufficiently so to treat it differently from other species of Goniopteris.

1. L. cochleata, Bedd. (F.S.I.). Lastrea filix-mas, L. ; var. cochleata, 



Bedd. {F.I.C.) ; Nephrodium cochleatum, Do7i. 



A tufted large fern Mith dimorphic fronds, barren sub-2-pinnate or 

 pinnate and pinnatisect reaching 3^ ft. by 18", ovate or oblong- 

 lanceolate or broadly-lanceolate ; pinnae 12-18 prs. close, lowest 

 often 8-9" by 3" oblong-lanceolate, pinnules lobed or not, denticulate 

 or serrate, with translucent clavate ends to the nervules, nearly 

 glabrous. Fertile fronds narrowly lanceolate and smaller, 2-pinnate, 

 thickly covered on the somewhat concave under-surface of the oblong 

 pinnules with the brown or grey indusia of the large sori which are 

 •08" diam., each of which sometimes occupies a separate rounded 

 toothed lobule of the pinnule. 



A common fern on shady banks, and the Indian plains representative of the 

 Male Fern (i. filix-mas, L.). Purneah ! Santal Parg. ! Kanchi and Palamau, 

 common at 3000 ft. ! Hazaribagh, ascending to top of Parasnath ! Manbhum, 

 Camp. ! Angul ! Mayurbhanj ! Fr. Sept.-Jan. 



Rhizome woody very stout horizontal and ascending, thickly covered with the 

 old leaf bases and with large brown shining scales. Stipes pale shining 6-12" in 

 the barren, sometimes 2 ft. long in the fertile frond, base with brown fibrillie and 

 linear or lin. -oblong scales -2- -4" long similar to those on rhizome. Rhachis 

 terete, grooved above, firm, glabrous, or with a few fibriUae and hairs which may 

 also occur on the secondary rhachises esp. in the fertile frond ; sec. rhachis in bar. 

 fr. nearly always more or less winged by decurrent blade. Basal pinnae spreading 

 or somewhat reflexed in bar. fr., in fertile frond erect, pinnae of fer. fr. 7-12 prs. 

 (exc. subsidiary lobes), not exceeding 3-4" ; pinnules of bar. fr. oblong or ovate- 

 oblong attaining 1-5" by -5" when lobed, or usually about 1" by -25- -3" when 

 merely serrate; of fer. fr. rarely over -6" by lb" and often only -15" long and 

 broad, lobules often spiuulose serrate. The barren frond occasionally bears a few 

 sori which are generally smaUer than those of the fer. fr. Indusia persistent 

 orbicular-nephroid with sinus quite closed, glabrous. 



The rhizome does not appear to be used. 



Var. marginata, Hope. Barren fronds deltoid completely 2-pinnate at base 

 with sec. pinnae cut four-fifths down into oblong serrate segments. Meghasani.

2. L. calcarata, Bedd. Syn. Nephrodium falcilobum. Hook. 



A tufted fern from 8" to 2 ft. high. Fronds lanceolate or oblong- 

 lanc, pinnate with the pinnae pinnatifid or pinnae only lobed, in one
