cicutariwn.) Aspidium Zollingerianum, Bedd. F. B. I. t. 251, fertile 

 frond only. Nephrodium (Sagenia) variolosum, Hook. Sp. Fil. 298, 

 and Zollingerianum {I.e.) as far at least as the Birmese plant. 



East Bengal Plains, abundant from Assam to Chittagong; 

 Tenasserim near Moulmein ; Penang. 



7. Aspidium polymorphum. {Wall.) Rhizome suberect, 

 stipes tufted, yellowish or brown, paleaceous only at the base ; fronds 

 large, 1-4 feet long, by 1 foot or more broad, pinnate; pinnae 3-6 on 

 each side, oblong or elliptic, acuminate, unequal at the base, some- 

 times contracted when fertile, quite entire to crenate or coarsely 

 toothed, stalked or subsessile, the terminal one often more or less 

 lobed or subpinnatifid, the lowest pair generally (not always) bifur- 

 cate ; texture herbaceous to subcoriaceous ; main veins prominent 

 and distinct to the margin, with many free included simple or forked 

 veinlets ; sori on the netted veins, small and scattered in the un- 

 contracted fronds, large and more or less in two rows between the 

 main veins in the contracted ones ; indusium reniform or often 

 quite absent. Wall. Cat. 3S2. Hook. Syn. Fil. p. 297. Bedd.

 Northern India from Gurwhal to Mishmee and Chittagong ; Ceylon ; 

 Birma. 



(Also in the Malay Islands, the Philippines and Fernando Po.) 



8. Aspidium Simonsii. {Baker.) Very like polymorphum, 

 but with the stipes arid rachis polished blackish-purple, lowest pair 

 of pinnae pinnate below, deeply lobed upwards, others more or less 

 bifurcate below and rather deeply lobed throughout, venation as in 

 polymorphum ; sori rather large (in my specimens), in two series 

 between the main veins, or irregularly scattered sub-4-serial between 

 the main veins. Hook. Syn. Fil. 504. Bedd. Sup. Ferns, t. 367. 



Seetakand Hill, Chittagong ; Sikkim, and Bhotan. Mr. Clarke,
