48 Ferns of British India and Ceylon. 



2. Pleocnemia Trimeni. This must be altered to Pleocnemia 

 gigantea {Bl.), as it is the same as the Java plant of Blume. It is 

 the gigantea of the second edition of the Syn. Fil. p. 503, but 

 only part lythat of Hooker's Sp. Fil. iv. p, 50, and of first edition 

 of the Sy?i. Fil. Perak {Dr. King's collectors, No. 327 and 2,043). 



2A. Pleocnemia megalocarpa. {Hook, under Dictyopteris.) 

 Caudex erect, scaly at the crown ; stipes stout, 18-20 inches long, 

 scaly towards the base ; fronds 2 feet or more long ; oblong- 

 deltoid, pinnate ; pinnae about 10 inches long, 3^- inches broad, 

 cut down to a broad rachis into narrow oblong crenated segments 

 about ij inch long, f inch broad ; texture subcoriaceous, opaque ; 

 above furnished with scattered, small, jointed, transparent scales ; 

 venation pleocnemioid in the wing, and there forming areoles ; 

 in the lobes also the veins anastomose, and form a series of 

 areoles near the midrib, but are free towards the margin ; sori 

 medial or nearly so on the veins, in two rows on each side of the 

 costa along the wing, and in a single row on each side of the 

 midrib in the segments. Hook. Sp. Fil. v. 102. Syn. Fil. 318. 

 Nephrodium oligodictyon. Baker, Ann. Bot. v. 328. 



Larut, Perak, 2,000-2,500 feet alt. {King's collector, No. 2,236.) 



(Also in Java.) 



3. Pleocnemia membranacea. Perak, 300-600 feet alt. 

 {Scortechinz, King, No. 2,191.) 



4. Pleocnemia membranifolia. The lamina of the fertile 

 fronds in the Indian examples often becomes very contracted and 

 narrow, though it is sometimes as fully developed as in the sterile 

 frond ; these contracted forms Mr. Clarke calls var. dimorpha 

 {Jour. Linn. Soc. xxv. 96.) From the Malay Peninsula, however, 

 Scortechini forwarded examples as fully contracted as any typical 

 Acrostichum (Stenosemia) auritum, together with various inter- 

 mediate stages from quite uncontracted, and pointed out that 

 there is no distinction between the two ferns. He is quite 

 correct, the sterile fronds, scales, indumentum, &c, offering no
