succession of fronds in one season : these are 1 — 2 fully developed, 1— -2 yourg 
ones emergen!', and several, withered laminae on the rhizome.’* The rhizome is 
M elongated 99 upwards, not horizontally. As I find this plant agrees with 
the figures given in Britten’s ‘ European Ferns ’ for 0. lusitanicum, I place 
it under that species provisionally, though I was at one time minded to 
make a new species of it — 0. Aitchisoni* Tt appears to me quite unlike 0. 
vulgatum. 
Mr. Clarke remarks : — “ A. Braun, in 8euber, FI. Azorica 17, descrih an 
0. polyphyllmi ; 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. lusitanicum , L., and 0. • polt/phyllum , A. Br., by H. C. Watson is to 
he found in “ The Azores,” by F. du Cane Godrnan, 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. 0. Watson by Bobert Shuttlewortb, Ph. D. } 
of 17th July 1871, which Mr. Baker has shown me, 1 find as follows : — “ 89, 
Although no Ophioglossum is in Drouet ’s collection, I have abundant speci- 
mens of the so-called 0. lusitanicum of the Azores. This has nothing really 
in common with the true 0. lusitanicum . I cousider it a distinct species from 
O. vulgatum (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 1 have received it, or a similar species (which for the present, on 
account of an apparent midrib— false, piobably — I have called 0. Reverchoni) 
from the neighbourhood of Briangon (Hautes Alpes) in good specimens, but as 
being very rare.”

I cannot make out the difference between O. vulgatum . , L., and O. reticulatum, 
X., unless it he that the net-work of veins is fine all over the frond in the latter
