Transcribed Image Text:IDENTIFICATION OF FERNS
The objective of this practical is for you to identify the genus of true ferns (Phylum
Polypodiophyta) based upon their leaf blade characteristics.
Instruction:
1. Draw the FIVE named ferns below
2. Label and describe the leaf type and leaf arrangement of the species
3. Search a taxonomic key for ferns
4. Identify the species of the ferns and its Family by using the description from
the taxonomic key
(You may refer to any taxonomic keys from references, OR you may use either
the two provided taxonomic keys, if the ferns are applicable)
a)
Salvinia sp (floating fern): Fronds round, fingertip-sized, bent in the middle;
tiny hairs apparent upon close examination of the upper side; form loose
mats
b)
Azolla sp (mosquito fern): Fronds irregularly branched, like flattened juniper
twig
c)
Lygodium sp (climbing fern): Fronds 1" to 12" long; forms thick climbing
mats
d)
Asplenium sp (bird's nest fern): Fronds flat, wavy or crinkly; forms a rosette
e)
Nephrolepis sp (Boston fern): Fronds long, lacy and narrow; forms a
delicate arch
