to describe it as a Fern, to which Linnæus gave the name ` 
of Polypodium Barometz. 
About fifty years ago the late Mr. John Reeves, who had 
long resided at Canton, succeeded in obtaining living plants 
of it, which he transmitted to this country, and which first ' 
produced fructification in the Birmingham Botanic Garden, 
which having come under my notice it became at once 
obvious that it was a species of Oibotium, and which, in my 
Definition of Ferns, 1841, I called C. Barometz. 
A closely allied species, C. Cummingii, is found in Luzon, 
and another, C. Assamica, in Assam; this Fern also 
appears to be represented in Sumatra, as some of the 
soft silky hairs similar to those of Barometz have been 
imported from that island into Holland, under the name of ` 
" Penghawar D’joumbi,” and are found to be useful as a 
. styptic. 
— €. Ohamissoi, O. Menziesii, and C. glaucum, natives of 
the Sandwich Islands, differ from C. Barometz in being 
arborescent, the stem of C. glaucum attaining the height of ` 
24 feet, the crown of fronds adding 12 feet more, making - 
the total height of the tree 36 feet. The base ofthe stipes - 
of the fronds is densely furnished with fine silky hairs, Ss 
which being permanent clothe the stem, forming a thick 
wool-like coat, which is collected and used for stuffing ` 
cushions, mattrasses, and the like, During the ten years — 
previous to 1865 it became an grücle of commerce under | 
the name of Pulu, and ship loalls of it were sent to Aus- 
fratia and California, but lately it has fallen into Ze,
