72 TWO NEW ATHYRIUMS FR():M THE N.W. HIMALAYAS. 



free frond-filaments. The young frond-filaments of A. pap)ia7in are 

 (as has been pointed out) also quite free. TJje Chlorodesmis-iovm in 

 fact seems to stand in much the same relation to Avrahivillea as the 

 Espera-fovm. does to Penicilbis, according to the interesting research 

 of M. Woronin. In many specimens the characteristic constriction 

 of the filaments is situated a short distance above their bifurcation, 

 and one is often a little higher than the other.

TWO NEW ATHYEIUMS FROM THE N.W. HIMALAYAS. 

 By Col. R. H. Beddome, F.L.S. 



Asplenium (Athyrium) Duthiei, n. sp. — Rhizome wide- 

 creeping, black, nearly naked ; stipe 3-4 in. long, furnished with a 

 few ovate or lanceolate deciduous scales, glabrous, pinkish ; fronds 

 narrow, ovate-lanceolate, about 12 in. long by 3-4 in. broad ; 

 pinnaB lanceolate, alternate, about 20 on each side ; lower ones 

 gradually reduced, the central ones 1^-2 in. long, i-f in. broad, 

 piunatifid nearly or quite to the rachis into sharply-toothed obovate 

 or lanceolate lobes about 2 lines broad; texture herbaceous ; rachises 

 glabrous, pinkish, furnished with a few deciduous large lanceolate 

 scales ; both surfaces glabrous ; veiulets forked ; sori asplenioid or 

 hippocrepiform, G-8 to each pininile or lobe, /. e., 3-4 on each side 

 on the lower veinlets midway between the edge and the midrib. 



Collected by Dr. Duthie in the N.W. Himalayas. No. 389, 

 Gaugotee, near the source of the Ganges. No. 392, linder Srikauta, 

 12-13,000 ft. No. 36G7, at Ralam Glacier, Kumaon, 12-13,000 ft. 



It is very similar in cutting to Lastrea Brunoniana. Dr. Duthie's 

 three specimens had been sorted into that packet at Kew where they 

 were detected as an Athyrium by Mr. Hope.
