Abstract: Leaf morpho-anatomy and indumentums of ferns and fern allies along Mae Yen waterfall nature trail were studied. Forthy three species belonging to 12 families of fern (21 genera and 37 species) and 1 fern ally’s family (1 genus and 6 species). This research provides plant descriptions, indumentum characteristics, stipe and leaf epidermal anatomy. All data was analysed to find unique characteristics of family or genus and to develop keys to family and species of ferns and fern allies at Mae Yen waterfall nature trail. The results showed that the indumentums can be used to classify ferns and fern allies into 3 groups. Four types of stele were found including protostele, solennostele, dictyostele and eustele. The epidermal cells were jigsaw shape. For types of stomata, anomocytic type was found in fern allies whereas 4 types were found in ferns including anomocytic, polocytic, paracytic and pericytic. The study showed paracytic stomata was unique characteristics of Equisetum and pericytic stomata was unique characteristics of Pyrrosia. The knowledge from this independent study was used to develop the teaching materials for laboratory manual in the topic of preparation of semi-permanent slide of leaf epidermal tissue which was used for teaching in science subject and basic science laboratory for Grade 11th.
