pouring through fissures into the valley below. This fem was 
also seen growing in several places on the hill above on the west 
side of the valley, where water runs out of rocks at 8000 feet, 
The ground here must be under snow for certainly four months, if 
not more. ‘There is close by here a crater, apparently of volcanic 
origin, which may account for the fern being found here, but no 
difference was perceptible in the temperature of the water.”’ 
Another remarkable westerly and northerly extension of a tropical fern is the 
case of Lygodium microphyllum, A. Br., which ane was found by General Gatacre 
in the Zidrat Valley, at 5000’ alt.

Beddome’s description amends -that in the Synopsis Filicum as regards the 
veins, which anastomose distantly in the fertile fronds, and closely in the sterile 
ones. But I would add that in pressed and dried specimens the whole fertile 
frond—stipes, rhachises, and lamina—appears homogeneous, and the stipes even 
is veined. Living plants should be examined as to this. 
T have seen this fern in its natural state only in the Dehra Din. Mr. Angus 
Campbell and I were on an elephant, picking out a line for the proposed railway 
from Hardwar to Dehra (since constructed and lately opened for traffic), and on 
seeing water draining froma swamp I said—this looks like a place where 
Ceratopteris would grow.” I had hardly spoken when I saw bright green patches 
in the water, and told the “ Mahaut” to get down and hand up a sample: it 
proved to be this fern. Both here and at Mr. Campbell’s station,-a few miles 
westward, the plant was of course rooted, as there was a considerable current.
