Abstract. The present study analyzed the characteristics in
leaf of Terrestrial Orchidaceae member i.e different species ofHabenaria Wild ( H. plantaginea Lind1.,H. ovalifolia. Wight., H. multicaudataSedgw. , H. crinifera Lind1 ., H.
heyneana. Lindl., H. elwesii Hook.f., H. longicorniculataJ.Graham. , H. pelorioides Par. & Rchb.f. (Odisha
cleistantha S.Mishra).). Anatomical characters are important in
identification and ecological adaptations. The anatomical characters
have serving as a tool for the genus’s systematic. The plants was
collected at different forest types from Shivamogga district. Materials
was fixed in FAA solution. Transverse sections were obtained by freehand
sections, stained with 1% safranin. Leaf anatomical organization ofHabenaria species ( Stomata ,epidermis, mesophyll, vascular
bundles, hypodermis.) was observed. There was a distinct variation in
the anatomical characters of the leaf. Detailed leaf anatomical
characters can be used to distinguish species from others. Leaf
anatomical characters with structural adaptation helps plants to survive
in different vegetation. The implication of this study is the importance
of leaf anatomical features to support species identification and to
increase understanding of orchid biology which are important in orchid
conservation.
