Ilab. Nepal, Wallich. Assam, Griffith. Khasia, temperate region, alt. 6000 

 feet. Japan, Goring, n. 128 {Metfeniun). — This fine species, thoiigli only re- 

 cently described and figured by Kunze as a Japan plant, has been long known in 

 British, and, jjcrhaps, represented by less perfect specimens, in Continental her- 

 baria, as the Acrostichum triquetrum of Dr. Wallich ; and I must do Dr. Wallich 

 the justice to say that in his MS. volumes of Indian Ferns in my possession, he has 

 accurately describeil what I consider the most remarkable feature of the Plagiogyria 

 section of Lotnaria : — " Stipites fragiles, 12-18-pollicares, basi crassi carnosi 

 triquetri, angulis membranaceo-marginatis acutissimis, latere interiore latiore 

 piano, reliquis convcdis." lie failed to observe the peculiar glands, and he has 

 united into one species what I am here disposed to consider as two, and which 

 have been so described by others. But it is to the present plant that Dr. 

 Waliich's name of Acrostichum triquetrum is attached in my herbarium. Ap- 

 propriate as the name is, seeing it has never been accompanied by any description 

 or character till after the publication of Kunze's Lomaria euphlebia, I do not 

 hesitate to adopt that latter name. There can, I think, be no question of the 

 identity of Kunze's plant and ours. It is by no means a solitary instance of a 

 Fern of the mountain districts of eastern Bengal being common to Japan. 



27. L. (Plagiogyria) pycnophylla, Kze.; caudex stout erect 

 very woody and having many wiry roots, fronds fascicled, 

 stipites subquadrangular 2-furrowed in front (as is the rachis) 

 at the base dilated lieshy triquetrous subalate bearing spongy- 

 glands, fronds 1-2 and more feet long, sterile ones subchar- 

 taceous opaque brown when dry, oblong-ovate pinnated for 

 its whole length except that the small terminal ones are con- 

 fluent into a lobed (or pinnatifid) and finely acuminate and 

 serrated apex, pinnee horizontally patent sessile or very 

 nearly so numerous approximate narrow oblong-lanceolate 

 very finely almost caudately acuminate, the base very obtuse 

 and truncate (neither dilated nor contracted) at the base be- 

 neath furnished with one or two prominent glands (some- 

 times wanting), the margin very minutely serrulate, the 

 caudate apex strongly serrated, veins numerous closely placed 

 simple and forked, fertile fronds narrower pinnated, pinncc 

 linear obtuse on very short petioles with a gland on the 

 under side, sori as in the other Playiogyrice, involucre at 

 first vaulted conspicuous membranaceous brown at length 

 forced back by the capsules. (Tab. CXLVIII.) — Kze. in Bot.
