 Kl. — This is, I think, a good species, but, like other Asplenia, very difficult of 

 definition on account of its variable pinnae. It has been in Herbaria confounded 

 with A. Icetum, Sw. (A. abscissum, Jl'illd., a name still retained by Mettenius, 

 but his synonyms and references sliow that this is the species intended by him). 

 It differs from that in the less coriaceous fronds, in the absence of distinct 

 auricles, etc. It has also by Kunzebeen compared with A. marinum, which is of 

 a more succulent nature, has auricled pinnse, and shorter and black stipites. 

 Moore quotes Plumier's Fil. Am., t. 61, under his A. abscissum. It may be an 

 exaggerated form of our A. Icetum, but such figures are little aids to botanists. 



94. A. (Euasplenium) Borneense, Hook. ; stipes short thick 

 furrowed in front 3-4 inches long (perhaps much more when 

 perfect), frond more than 3 feet long 2\ inches broad, subco- 

 riaceo-membranaceous dark-green opaque elongato-lanceolate 

 acuminate? (apex imperfect) long-attenuated below pinnated, 

 pinnte very numerous approximate almost imbricate at the 

 base spreading nearly horizontally oblong falcate very obtuse

 and under his A. abscissum.
