Under the head of “ Distribution ” the Synopsis gives the Himalaya gener- 
ally, and the other authorities give Nepal as the Eastern limit ; hut the same, 
comparatively glabrous, plant is got in Sikkim, for in Mr. Gamble’s collection I 
find three sheets from Goke and Singtam (Darjiling) and from the Jeylep 
Road ; and there is also a sheet from Manipur — Nonjaibang 750', Clarke 
No. 42338, 1885. 1 have a specimen of Clarke’s from West Manipur 1000', 
1885. D. lasiopter's, Kunze, which Clarke, and (whom following) Beddome, 
unite with A.japonicum, is rougher and coarser looking, and D. thtvaitesii , 
Bi\, and A. decussatum , Wall. (D. polyrhizon , Baker), though also so 
united by the same authorities, seem to have their differences. Beddome’s 
figure, E. B. T. 292 of the latter, shows an isolated plant with an erect caudex, 
but he says he has found typical decussatum with the rhizome creeping, though 
it is generally erect : this shows that he has confounded two distinct species, 
for this statement involves a physical impossibility. A fern with a slow grow- 
ing, erect caudex may be fixed in a recumbent position and then grow hori- 
zontally ; but that is quite a different case from that of a plant with a thin quick 
growing rhizome sarmentum which creeps and branches underground, and 
throws up fronds at intervals, forming a bed. But as no one has attributed 
any of these three similar plants to N.-W. India, I need not further deal with 
them.

Blanfcrd, who figures a small frond of this (PI. XVI., Journ. Asiat. Soc., 
Bengal, 1888), says he gives this species on Mr. Clarke’s authority, but he had 
regarded it as merely a simple form of A. polypodioides , Mett. Clarke and 
Baker have given Simla, Alt. 6000 ped., H. Blanford, as an additional 
habitat, in their joint paper referred to above. The specimen is in Kew. 
Beddome seems to consider this plant as merely a variety or form of A, poly- 
podioides .
