bottom, however, marked their specimens Phymatodes cyrtolobum, J. Smith, and Baker 
accepted this reduction. Nor do I feel sure P. Stewartii may be not the erect form of 
P. cyrtolobwm. But contra, my very large collection of P. cyrtolobum has not an example 
that tends towards P. Stewartii in any point; and, secondly, if P. Stewartti is to be 
reduced to a var., it seems to me nearer P. ebenipes, or even nearer P. hastatum, than to 
P. cyrtolobum. l 
58. P. manacopoy, Hook. Sp. Fil v. 87, excl. B. Rhizome rather slender, somewhat 
extensively creeping; scales lax, lanceolate-linear, brown-black; frond often sub- 
cordate at base; margin acutely. serrulate; teeth mucronate, often spinescent.—

Nepaul to Bhotan, alt. 10,000—13,000 feet ; very common, €. B. Clarke. 
A very common fern, known at once by its strongly serrate margin. It is remarkable 
that I find no example in the Kew Herbarium (other than my own), except some pieces 
mixed on a sheet of T. Thomson’s, said to have been collected “ Top of Hattu, alt. 
10,500 feet, in the North-west Himalaya." 
59. P. EBENIPES, Hook. Sp. Fil. v. 88. Rhizome somewhat widely creeping, stout, with 
adpressed lanceolate black scales, similar scales often present on the main rhachis 
beneath ; margin minutely serrulate, teeth not mucronate.—Hk. & Baker, Syn. Fil.

From Gurwhal to Bhotan, alt. 6000-11,000 feet; very common. 
The scales on the rhizome often have rusty almost yellowish tips ; the fern is, however, 
then (as are. scraps without rhizome) easily sorted from P. hastatum (oxylobum), by the 
serrulate margin. The real difficulty is to separate it from P. Stewartii, Bedd., which 
I think can hardly be done in the absence of the rhizome.—1 have collected plants of Rois 
from young rhizomes with simple entire fronds. 
Var. B. Oakesü. Large; pinne 5 by j in., caudate; rhachises above hairy. 
Darjeeling, alt. 7000 feet ; Dr. Jerdon, C. B. Clarke —As this fern grows in Darjeeling 
station I have often observed it, and doubted whether it was worthy specific rank. The 
pinns are cut down very nearly indeed to the main rhachis, as many as 15 on each 
side, and very unlike the common outline of P. ste ap but the rapa — seales are 
typical ebenipes.
