MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 567 
Var. niphoboloides. Surface beneath densely brown tomentose, the sori buried in the 
tomentum. 
Bhotan, Griffith.— But there is a series of examples connecting this var. with the type. 
—As to the name of this species, I cannot find where P. venustum, Desv., was described ; 
it has, at all events, so completely slipped out of sight that it no way interferes with 
P. venustum, Wall. 
67. P. LEIoRHIzON, Wall. Cat. 308, chiefly. Rhizome creeping shortly, with lax slaty- 
brown, ovate, not acute scales; pinnze narrow, lanceolate-linear, coriaceous ; primary 
parallel veins hardly more prominent than the secondary venation, with one sorus 
between each pair of such parallel obscure veins.—Mett. Fil. Hort. Lips. 37, t. 25.

Lachen Valley, Sir J. D. Hooker.—Distrib. South Europe and the Mediterranean Region 
from Maearonesia to the Caucasus and Abyssinia. 
The scales on -the back of the fronds may be called “ pseudo-wool"' (Añvoc); I do not 
see how the fern can be said to have a **pseudo-indumentum ;" it has a real indu- 
mentum. Rob. Brown called it Notholena ; and I am convinced that he meant Notholena, 
and that Desveaux blundered.
