29. The following Analysis consists of two tables. 
Table first containing genera, the second species. 
Table I should be studied with the aid of any ferns 
at hand, and the principal genera made familiar, 
Asplenium, Aspidium, Nephrodium, Polypodium, then 
Davallia and Gymnogramme, and in the southern 
Himalayas, Acrostichum. When a plant can at sight be 
assigned to one of these genera, the student will find his 
labor easy. Fronds should be gathered at intervals by 
the way, examined, and the genera determined for practise 
until the horseshoe shapeu sori of Athyrium is not liable 
to be mistaken for the full kidney sorus of Nephrodium. 
When Table I is thus mapped out m memory so as to 
require only occasionally consulting, reference to the 
genera can be made directly to Table II, and the name 
of the fern under examination at once found. 
30. Abbreviations have been freely used to save 
space and facilitate reference, but with the occasional full 
printing they need be no puzzle, as pinjid. for pinnatifid, 
membr., cor., for membranaceous, coriaceous, fr. and segm. 
— frond and segment, &c.
