PERKS : BRITISH AKD FOREIGN. 
between the fascicles of veins, and varying so ranch in 
the more or less compound division of its fronds, that 
one state of it was described as a distinct species by 
Sir W. J. Hooker, under the name P. myriocarpon ; 
Asplenium Sandwichianum, with large tripinnate 
fronds three feet high, with numerous small segments, 
bearing some resemblance to a Mimosa leaf, and others 
too numerous to mention. 
The Galapagos, although not rich in Ferns, are 
worthy of notice, on account of a very rare and 
remarkable species, first described and figured by 
Sir W. J. Hooker, in the “ leones Plantarum,” 
under the name of Acrostichum (Neurocallis) aureo- 
nitens, and more recently in the fifth vol. of the 
“ Species Filicum ” as Acrostichum ( Chrysodium ) 
aureo-nitens. Judging by either of the sectional 
names, it might be supposed to have some resem- 
blance to the well-known Acrostichum aureum , but 
such is not the case, reticulated venation and appa- 
rent amorphous sori being the only characters that 
place it in that alliance ; in habit it is totally dis- 
tinct, just as distinct from Acrosticum ( Chrysodium ) 
aureum as Ceterach offidnarum is from Asplenium 
(Hemidictyon) marginatum. The plant has simple 
barren and pinnate fertile fronds 6 to 10 inches in 
length, the whole plant being densely clothed with 
shining scales. To me its relationship seems to be 
with Hemionites vestita , a beautiful Fern of India, and 
also with another little-known species, the Gymno- 
gramme ( Eugymnogramme ) Muellerii, a native of 
north-eastern Australia, described and figured by Sir 
W. J. Hooker, in the fifth vol. of the “ Species Fili- 
cum,” which also seems to me to be closely related to
