 form, like the Indian P. GreviUeana, Wall., but the barren and 

 fertile fronds not dimorphic. The texture firmer than usual. The 

 rachis with a broad wing, as in P. hiaurita, and the veins crowded 

 and obscure.

203.''-' Asplenium (Diplazium) porphyroeachis, Baker. Caudex 

 suberect, producing many short-stiped barren fi'onds to a few 

 long-stiped fertile ones. Stipes purple, of the barren h'ond two to 

 three inches, of the fertile six to twelve inches long, clothed 

 throughout with spreading black linear- subulate paleae. Frond 

 lanceolate, six to twelve niches long, one to two inches and a half 

 broad, cut down throughout to a narrow wing to the rachis, which 

 is purplish in colour and clothed on the under side with spreading 

 paleae, like those of the stipe. Pinnae lanceolate, one-quarter to 

 one-third of an inch broad, toothed towards the tip, several of the 

 lower ones reduced in size. Texture moderately firm. Both 

 surfaces glabrous. Veins fine, close, distinct, erecto-patent, 

 usually once forked. Sori reaching from the midrib to the edge, 

 few double. Involucre narrow, x^ersistent, glabrous. — This is the 

 plant described by Sir. W. Hooker from a single barren h-ond without 

 fruit gathered by Mr. A. K. Wallace, as Polyjjodiiun subserratum 

 (Hook, and Baker Syn. Fil., p. 325). In Asplenium that specific 

 name is already occupied. Of the present ]3lant A. zeylanicum, 

 Hook., is the only near ally. The same species was gathered by 

 Beccari near Sarawak.
