THE FERNS OF NORTH-WESTERN INDIA. 107 



succession of fronds in one season : these are 1 — 2 fully developed, 1 — 2 young- 

 ones emergent, and several withered lamina? on the rhizome." The rhizome is 

 *' elongated " upwards, not horizontally. As I find this plant agrees with 

 the figures given in Britten's ' European Ferns ' for 0. lusitanicwn, I place 

 it under that species provisionally, though I was at one time minded to 

 make a new species of it — 0. Aitehismi. U appears to me quite unlike 0. 

 vulgatum. 



Mr. Clarke remarks : — " A. Braun, in Seuber, Fl. Azorica 17, describes an 

 0. polyphyllum ; but this has venose fronds, the whole plant only 1 — 2 in. high, 

 and comes from Terceira, and is probably not near 0. Aitchisoni." A discussion 

 regarding 0. Insitamcum, L., and 0. polyphyllum, A. Br., by H. C. Watson is to 

 be found in " The Azores," by F. du Cane Godman, F.L.S., F.Z.S., &c, and in 

 manuscript " Notes on the plants contained in the collection made by M. Drouet 

 in the Azores in 1857," sent to H. C. Watson by Boberfc Shuttleworth, Ph. D. 

 of 17th July 1871, which Mr. Baker has shown mo, I find as follows : — " 89. 

 Although no Ophiogloss'um is in Drouet 's collection, I have abundant speci- 

 mens of the so-calkd 0. lusitanicum of the Azores. This has nothing really 

 in common with the true 0. lusitanicum. I cousider it a distinct species from 

 O. wig at urn (under two of the forms of which Milde quotes it) for it is appar- 

 ently widely distributed— Silesia (Milde). I have it from Arabia and else- 

 where ; and I have received it, or a similar species (which for the present, on 

 account of an apparent midrib— false, probably — I have called 0. Reverchoni) 

 from the neighbourhood of Briancon (Hautes Alpes) in good specimens, but as 

 being very rare.''

I cannot make out the difference between O. vulgatum, L., and O. reticulatum, 



L., unless it be that the net-work of veins is fine all over the frond in the latter
