658 Maxon: A NEW ASPLENIUM 
Asplenium modestum is apparently an aberrant member of the 
lanceolatum group of Hooker and Baker’s Synopsis Filicum, its 
nearest Mexican allies being, perhaps, A. szcropteron Baker and 
A. Glenniet Baker, the latter hardly distinct from the Asiatic 
A, exiguum Bedd. From these, however, it differs conspicuously 
in many particulars, but notably in its wholly green stipes and in 
its broad divided pinnae, the lowermost scarcely at all reduced. 
The flabellate aspect of the pinnae is pronounced and should serve 
at once to distinguish the species. 
The writer is indebted to Mr. H. D. House for the accom- 
panying drawing, which represents at natural size one of the five 
fronds of the type-specimen before mentioned.
