THE FERNS OF NORTH-WESTERN INDIA, 453 
A Mussooree specimen of the type plant, I got long agos has 9 ears—3 on each 
side of the two lowest pinnee, 1 on each of the two next above, and the $th on 
one of the third pair, And I have another frond which has a remarkable 
development : it has deflexed ears on the three lower pairs of pinne, and 
abnormally developed inferior lower segments up to the seventh pair ; but it 
has also ears pointing upwards on the superior side of the lowest pair of pinne, 
two on each of them. These are not so large as the ears on the inferior side, 
but yet are about two inches in length, deeply pinnatified, and fertile like the 
rest, I have seen a frond collected by Mr. J. Marten, in Chamba, of which the 
fifth lowest pinna on the left side is prolonged, and as compound (bipinnate) as 
the frond itself,—the pinnules equalling in size the pinnee of the main frond. 
I have not seen on N.-W. Indian specimens of this fern the adventitious buds 
which are found on specimens from elsewhere, and are mentioned in books. 
Thinking these to be parasitical growths, I referred the question to Mr. G. 
Massee, F.L.8., of the Royai Herbarium, Kew, and he kindly looked up the 
subject, and showed me that Giesenhagen, in “‘ Flora,” 1892, says the abnormal 
growth is due to the presence of Taphrina Laurencia, Giesh. A similar growth 
on Asyidium arzstatum, Sw., is caused by Taphrina cornucervi, Giesh.

The following is Beddome’s description :— 
“* A small form, 8-10 inches high ; stipes stramineous ; fronds short deltoide 
lateral pinne, often only 1—2, rarely 8—4 pair, with a large terminal central 
pinna, segments long, nearly equally broad throughout, spreading at right 
angles from the midrib, lower basal segments of the lower pinnee only slightly 
enlarged and pinnatified, or quite entire and uniform with the others. 
Nepal (Wallich), Kumaun 2000, at Bagasar (Strachey and Winterbottom). 
Lachen Valley, “Sikkim,” (Levinge). Mr. Levinge’s specimens are more 
slender than Wallich’s type, more papyraceous in texture, and furnished with 
a broad, white band down the centre of each pinna; it would be a very pretty 
plant for cultivation.” 
N.-W. P. : Brit. Garhk.; (Found among the Mackinnons’ ferns, without ticket: they 
think it was got by Mr. P. W. Mackinnon in B. Garhwal in 1881—38 small fronds 
stipes incomplete) ; Awmaun—Sarju Vy,, Bagesar 3000’, S. and W. 1848, (named P.
