NEPIIIIODIUM, § LASTREA. 87 



entire or serrated chiefly above the middle, h)\vcr iMiina; dis- 

 tant, lobes of the apex obtuse, veins pinnated twice or thrice 

 forked, sori solitary dorsal on the lowest superior veiidet, 

 involucres coriaceous rotundato-cordiform and subpeltate, 

 rachis crinite with dark brown subulate scales. (Tab. 

 CCXLIII.) 



Hab. China: Foo-chow-foo, Alexander. — It is difficult to say if the involucre 

 is that of a Polystichum or Lastrea. The veins are free. Tlie hahit is very much 

 that of our A^. podophyllum («. 48), hut the frond is very much smaller, the 

 sti])ites are more slender and, as well as the rachis, want the large brown 

 ])eculiar scales of that species, the auricles of the pinnsc are entirely absent, 

 and the superior pinna; gradually become coadunate into a pinuatifid apex with 

 blunt segments. 



46. N. (Lastrea) semihastatum, Hook. ; caudex small 

 short copiously rooting, stipites tufted 2-3 inches long hairy, 

 fronds 6-8 inches long pubescenti-hirsute especially beneath 

 oblongo-lanceolate pinnated pinnatifid at the apex, pinnae less 

 than an inch long horizontal approximate subsessile oblong- 

 falcate very obtuse crenate at the margin auricled at the base 

 above rounded beneath, veins pinnated, sori small, involucres 

 " ciliated," rachis villous with patent hairs. — Aspidium, Kze.

Hab. Peru, dense woods at Pampayaco, Pceppiy. — This appears to be a good 

 species, hitherto found by no one but Pceppig. 



47. N. (Lastrea) Sieboldi, Hook. ; caudex short thick 

 densely paleaceous, stipites tufted 6 inches to a foot long, 

 fronds about a span long carnoso-coriaceous pinnate, pinnae 

 3-7-9 subpetiolate, lateral ones horizontally patent 6-8 inches 

 long an inch wide elongato-olDlong acuminate subfalcate trun- 

 cate or subcordate at the base hirsutulous beneath irregularly 

 crenato-lobate and serrated, sterile ones broader, terminal 

 pinna very large lobed or subpinnatifid at the base, veins 

 dichotomosely fascicled terminating within the margin, sori 

 dorsal on the veinlets very large and prominent, involucres 

 reniform convex. — Hook. Fil. Exot. t. 31. Aspidium, Van

 trea and Pycnopteris, Moore. Lastr. podophylla, J. Sm. [not 

 Hook.) 



Hab. Japan, Siehold. — A well-defined and most distinct species, but at present, 

 strange to say, better known in gardens than in the herbarium. 



48. N. (Lastrea) podophyllum, Hook. ; caudex a thick 

 scaly rhizome, stipites tufted a span to a foot long with in-
