The present study was aimed to describe the morphological and anatomical characteristics of the leaf, stem/pseudobulb, and root in
Coelogyne ovalis Lindl., (classified under section Fuliginosae) with a view to understand adaptations related to water regulation and their
taxonomic implications. The vegetative tissues were fixed and preserved in 70% alcohol, and sections were prepared using a rotary
microtome. Anatomical observations revealed that the key features namely the leaf exhibits stomata, a thick cuticle, and a vascular bundle
in the mid-rib; the stem contains specialized water storage cells and distinct tracheids; and the root possesses a multilayered velamen and
endodermal lignification. The inflorescence of Coelogyne ovalis is characterized as a stachyoid (or stachyoid-type) structure, which is
defined as a closed, determinate bracteous spike.
