XEPIIROniUM, § LASTREA. 123 



it is remarkable that the only specimens from those regions are what I here consider 

 the var. j3. — It is one of the most beautiful of all Kerns, in the minutely-divided 

 fronds, full-green, destitute of scales above, while the whole of the rest of 

 the jilaut is riclily jialeaceous with aureo-nitent scales. My finest specimens are 

 from Russian North-west America {Secmann), and from Manchuria {{I'ilford), 

 and the Anmr {Madimowicz). 



107. N. (Lastrea) Falconeri, Hook.; caudex ?, sti[)es a 

 foot long very coarse and stout quite squarrose for nearly its 

 whole length with large broad silky ferruginous soft scales 

 mixed witli smaller subulate ones, these latter only still 

 smaller also clothe the main and secondary rachises, fronds 

 1 ^ foot long oblong scarcely acuminate firm rigid coriaceous 

 slightly villous bipinnate, pinnee 4-6 inches long an inch 

 wide erecto-patent oblong-lanceolate, pinnules sessile linear- 

 oblong 4-f of an inch long about halfway down pinnatifid 

 with short round entire lobes, the margins reflexed, sori 

 rather large copious one to each lobe, involucre brown very 

 membranaceous cordato-reniform very convex so as to be al- 

 most hemispherical. (Tab. CCLIV.) 



Hal). Kashmir, Falconer. — This is a most distinct and very beautiful species, 

 with not a little of the habit of N.fragram, but, if I may so say, upon a gigantic 

 scale; the pinnules are lobed, so as to resemble those of the small Gleichenias 

 of South Africa. The rachises appear to be resinoso-glandulose. 



108. N. (Lastrea) Napoleonis, Bory; caudex a short thick 

 rhizome densely crinite clothed with very long erect flexuose 

 linear subulate glossy brown scales, stipites tufted 4 inches 

 to a span and more long smooth and glossy scaly only at the 

 very base (as is the caudex), fronds G-12 inches and more long 

 coriaceous deltoid or deltoid-ovate acuminate glabrous and 

 scaleless pinnate or usually more or less bipinnate below, 

 pinnce sessile oblong acuminate deeply pinnatifid with oblong 

 segments very obtuse and toothed at the margins, those of 

 the lower pinnae and the pinnules of the lowest pinnae more 

 elongated, those of the lowest pair on the lower side most 

 elongated especially at the base subacuminate and pinnatifid 

 the lobes coarsely serrated, veinlets simple or forked, sori 

 copious large close to the costule, rachis and costcc rigid and 

 polished. (Tab. CCLV.) — Aspid., Borrj, in Belang. Voy. Ind.

Hah. St. Helena: close to Napoleon's tomb, Wallich, Belangcr, Cuming, n. 

 434 ; on walls, rocks, and in woods near Diana's Peak, alt. 2000 feet, /. D. 

 Hooker, llarveg, Seemann, etc. — This rare and distinct species is peculiar, we 

 believe, to the locality above-mentioned.
