Hub. Woods on the clevaU'd niouiitaiiis of Java, Blume. Sylliol, Wal- 

 Ucli. Assam, Mrs. Mark, Mr. (JriJfil/i.—A fjraceful Fern, 2 — 4 feet high, 

 with rather a long stipes, ek)the(l below with very large, broad, opaque, 

 brown, membranaeeous scales. Similar scales, but smaller and almost ro- 

 tundatc, are seen at the axils of the jiinua; of the younger ])lants. I'ronds 

 tripinnate, primary pinnaj often nearly opposite : main and j)artial rachis 

 frequently beset with copious short setose scales, especially beneath, some- 

 times with long crinite scales which also appear on the veins above : these 

 afterwards disappear, and the rachis is then quite smooth. Pinnules sub- 

 membranaceous, oblong-euneate, pinnatifido-lobate, more or less decurrent, 

 so that the rachis of the ultimate pinna is generally winged : — the lobes 

 are deeper at the anterior edge. Veins dark-colored, simi)ly j)innale, the 

 veiidets undivided, not reaching quite to the margin. Involucres exactly 

 globose, attached by a small point, dark mahogany-colored. Presl has 

 strangely placed this in the geims Cistoptcris, and yet appears to have seen 

 a \\'allichian specimen in the Royal Berlin Herbarium. Kunze refers it 

 to the genus Physenuilium, but the firm texture of the involucre and the 

 whole habit of the plant seem to forbid such an union.

Hab. Summit of the mountain Burangrang, Java, Blume. — Of this we 

 have but a short and imperfect description given by its discoverer, Blume; 

 and its jdace among Ferns is doubtful to me. It is compared in its fruc- 

 tilication to Trichoptcris, Presl, or Chnoophora, Kaulf.; but the habit seems 

 very dilVcreut. A solitaiy specimen only apjiears to have been found, in 

 all respects resembling Aspidinm coriaccum, Sw., excei>t that the pinnules 

 are acute. " Nevertheless," Dr. Blume observes, " it cannot be associated 

 with the Aspidia, the structure of the involucre being so different. It con- 

 sists of a cobweb-like substance covering each sorus, soon evanescent, and 

 so tender that it can scarcely be said to form a membrane."'
