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 Silddm, 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. lasiopferis, Kunze, which Clarke, and (whom following) Beddome, 

 unite with il.yapmcMw, is rougher and coarser looking, and D, thimitesii, 

 A. Br., and A. decussatum, Wall. (D. polyrhizon, Baker), though also so 

 united by the same authorities, seem to have their differences. Beddome's 

 figui'e, F. 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 

 ik 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 gTow 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.

Blanford, who figures a small frond of this (PI. XVI., Joum. Asiat. Soc, 

 Bengal, 1888), says he gives this species on Mr. Clarke's authority, but he bad 

 regarded it as merely a simple form of A. polijpocUoides, Mett. Clarke and 

 Baker have given Simla, Alt. 6000 ped., H. Blanford, as an additioual 

 habitat, in their joint paper referred to above. The specimen is in Kew. 

 Beddome seems to consider this plant as merely a variety or fonn of A. poly- 

 podioides.
