This is one of those ferrs that are so common along the foot of the Himalaya 
that one neglects or postpones collecting them. It grows even by the road- 
side in the heart of the town of Dehra, and onwards to Rajpur on the way up 
to Mussoorie, Far to the southward I gathered it in 1860, in Bagelkhand, 
Centr. Ind., alt. about 800’. Mr. Gamble got it in Bengal—Lohdardaga Dist., 
Mr. Clarke in Centr. Ind., and Mr. Duthie in the Centr. Provs. Mr. Clarke 
says it is plentiful in ditches in Calcutta. 
The cutting of the pinnee of this species varies much, The largest fronds 
I have from Darjiling, collected by Zevinge, have entire pinnze, with only the 
marginal row of sori broken. Smaller fronds of the same gathering have pinne 
cut down 4 to 3-way to the lower edges, with one, two, or three lengths of 
sorus to each of the 5 or 6 lobes. In the Syn. Ful., the pinnz are said to be 
subdimidiate ; but I should say that the costa, or main vein, of a pinna 
forms the lower edge: the veins radiate from the attachment of the petiolate 
secondary rhachis, or from the costa near it, and may be said to be about 12 
in number at the base of the pinna. They form dichotomous groups stretch- 
ing to the lobes, and sub-lobes if any, and they continually fork or branch 
up to close to the edge of the pinna, until there must be from two to three
