382 ON THE VEGETATION OF CHUMEA STATE. 



Stipes 3-4-pollicaris ; lamina 4-5 poll, longa, 2-2| poll. lata. Pinnae 

 erecto-patentes, superiores sensim minores, inferiores 1 poll, late, petiolo 

 semipollicari ; segmenta tertiaria subquadrata 3-4 lin. longa, cuneata, 

 terminalia 2-3 lin. lata. Involucrum ^ lin. latum, ^-1^ lin. longum. 

 Intermediate between A. venustum and A. Capillus- Veneris : most 

 like the former in size and general habit, but the outer edge of 

 the barren segments obscurely crenulate, not distinctly toothed, 

 the sori narrower and often confluent, and not distinctly indented 

 into the segment, and the involucre different in size and shape 

 not nearly so large or so firm in texture.
