The quoted part of the description given above is Mr. Clarke’s, represent- 
ing, as he says, the fairly developed average, though he had examples much 
larger. The plate in Beddome’s Suppt. to F. B. I., t. 373, was, Mr. Clarke 
says, drawn from a high-level scraps and the description in the Synopsis, 2nd 
Ed. p. 498 ; seems to have been written from that scrap, which Is even more 
unlike N. F.-mas. than are the fairly developed fronds® which Mr. Clarke 
after wards (?) contributed to the Kew Herbarium, some of which run to 
fully 13 inches in length ; 6—7 inches is, however, the greatest breadth I see 
there. 1 have incomplete fronds collected by Dr. T. Thomson in Sikkim (?) 
which measure 16—17 in. 1., but they are not more than 6—7 in, br. These 
and some smaller fronds were named by Dr. Thomson (?) Nephr odium Bnmonia- 
, num var ,, but *are unlike that species. I would modify Mr. Clarke’s descrip- 
tion by saying that the pales are dark to pale chestnut ; that the segments are 
not serrate— only toothed so as to enclose the veinlets ; that the venation is 
very distinct ; that the sori are one to each of several of the lower lobes of the 
segments or pinnules, placed near the costa. Also that the secondary pinnae 
a*re never stalked, but have a broad base getting narrower near the main rhachis. 
The upper half or more of each pinmu is only bipinnatifid. Many small
