named species, and in the former five only near the margins, the meshes in the 
centre being long and narrow. Anyhow, I can see no difference between 
the N.-W. Indian specimens ana those I have gathered in Scotland, except 
that one of Gamble’s plants from Jaunsar and another of his from Katanga 
Hill in the Dun, both in my. possession, have two fronds, one of them sterile. 
So also has a specimen collected by Dr. King, in the Tees t a Valley, Sikkim, in 
1876. B.ddome, in Suppt. H. B., 1892, says lie believes “ all the Himalayan 
specimens are referable to retinRahim ; I can see no difference in the venation.'* 
Why, then, does he favour 0. rdiculatum ?

Indian specimens of this form used always to be ticketed B. domfolium, Wall. 
But I saw in Mr. Gamble’s collection a specimen of Mr. Clare’s, got in 
Assam in 1886, No. 45827, named B. daudfclwm y which seemed to me to be 
typical, and quite different from those others. A.bout the same time Mr. Trotter
