134 XEPHRODIUM, § LASTREA. 



below broad-oblong acuminate varying in length from 3-4 

 inches above to Ih foot in the lowest or basal pair their ra- 

 chises stramineous glossy singularly and broadly winged to- 

 wards the apex and decurrent till the wing gradually disap- 

 pears, secondary ones also distant subsessile 2-3-4 inches 

 long broad-lanceolate often finely acuminate, pinnules oblong 

 ^-f inch long horizontal lobato-pinnatifid with entire short 

 segments approximate with very narrow acute sinuses (in 

 this case the secondary pinnae may be said to be pinnatifid) 

 but more frequently they are distant with a broad sinus and 

 are all united by a wing on each side the costee analogous 

 to the wing at the extremity of the main rachises, veinlets 

 simple or forked, sori in two series between the costule 

 and the margin, involucres orbicular-reniform. — Aspidium 

 divisum, JFall. Cat. n. 393. Lastrea, Moore.

 Hills, Madras Presidency, Beddome, n. 175. — This is, as far as I know, quite an 

 undescribed species, nor have I ever received a named specimen ; but it is, accord- 

 ing to Mr. Moore, the Aspid. divisum of Dr. Wallich's catalogue. It is indeed 

 very distinct as a species, and must, judging from the specimens in my herbarium, 

 attain a very large size. In structure, and in the winged rachis, the secondary 

 pinnaj very much resemble the pinnae of N.flaccidum ; but that is small and 

 slender, and only bipinnate, and wants the decurrent wing towards the apex of 

 the main rachis. Although I have not seen a perfect caudex, one of my specimens 

 has a stipes which throws out stoloniferous wiry roots, like those of Nephrolepis.

 long (8-10, Wilson) 3 inches broad [Plum.) copiously subu- 

 lato-paleaceous, fronds most ample 12 feet long {Purdie, 

 16-18, Wilson) firm-membranaceous more or less villous or 

 pubescent especially on the costae often glandular beneath 

 tripinnate, primary pinnae distant from a span (near the apex) 

 to 2-6 feet long (in my herbarium) petiolate broad oblong-lan- 

 ceolate acuminate, secondary pinnae very numerous approxi- 

 mate 2-6-8 inches long H inch wide sessile oblong finely 

 acuminate deeply almost to the rachis pectinato-pinnatifid 

 or below quite pinnate, segments nearly horizontal approxi-

 less deeply lobato-pinnatifid the lobes entire, veinlets simple 

 or forked, sori copious in two series on each pinnule or large 

 segment between the costule and the margin one to each 

 lobule, involucres large plane persistent orbicular with a very 

 obscure sinus (apparently often quite peltate), rachises pubes-
