 kong, top of the ridge, Col. Urquhart, n. 29, 60, and 53, in various states be- 

 tween pinnate and copiously bipinnate. — From Ceylon, and Mauritius especially, 

 I have described a simply pinnated diplazioid Fern, which I take to be the 

 Diplazium sylvaticum of Svvartz and Willdenow, and Scbk. Fil. t. 85, b (see our 

 n. 267) ; but I am disposed to consider the present plant to be always difl^'ercnt, 

 and, when perfect, bipinnate. This is very abundant in Ceylon, but never, that I 

 know of, found in Mauritius. It is also a very common plant in India and the 

 Malay Peninsula, and, no doubt. Archipelago, etc. ; and it is very different from 

 any other of the Eudiplazium group. It has, however, a great deal the habit 

 of Aapl. (Anisogonium) esculentum, but that has anastomosing venation. An au- 

 thentic specimen of Hlume's A. dilafatum in my herbarium exactly corresjjonds 

 with this, a name which I therefore willingly adopt. The variation of the pin- 

 nules in different parts of the same specimen, renders it impossible to draw a 

 satisfactory character which shall include all their variations. 



285. A. (Eudiplazium) melanochlamys. Hook.; caudex ?, 

 stipes (upper portion only) 4-5 lines wide compressed and 

 angled dirty-brown, frond ample " (> feet in length" widely 

 spreading subcoriaceo-membranaceous deep green a little 

 paler beneath bipinnate, primary pinnae from 5-12 inches 

 long remote broad-oblong acuminate 3-4 inches broad at the 

 base, secondary pinnse or pinnules rarely petiolate sessile and 

 often decurrent on the pinnse towards the apex of the frond 

 and crenato-pinnatifid and then small 1-2 inches long, on the 

 lower pinnse 2-3 inches long from a rather broad base \ an 

 inch to 1 inch wide oblong acuminate deeply pinnatifid often 

 nearly to the rachis, segments oval-oblong obtuse serrated 

 approximate having narrow sinuses, veins pinnated in the 

 larger segments, veinlets simple or forked, sori narrow-
