38 TEENS : BKITISH AND FOREIGN. 



between the fascicles of veins, and varying so mucli 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 trip inn ate 

 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 "Icones Plantarum," 

 under the name of Acrostichum (Neuro call-is) aureo- 

 nitens, and more recently in the fifth vol. of the 

 " Species Filicum " as AcrosticJmm (Chrysodium) 

 aureo-nitens. Judging by either of the sectional 

 names, it might be supposed to have some resem- 

 blance to the well-known AcrosticJmm 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 Cetera cli officinarum is from Asplenium 

 (Hemidictyon) marginatum. The plant has simplo 

 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 (Eugymno gramme) Muellerii, a native of 

 north-eastern Australia, described and figured by Sir 

 W. J. Hooker, in the fifth vol. of the " Species Fili- 

 which also seems to me to be closely related to
