Abstract

The leaf, stem and root anatomy of Dendrobium crurnenatum Swartz and Dendrobium anus-mum Lindl. var. dearei were studied by making stained and unstained transverse sections and epidermal peelings in order to characterize and compare their anatomy and correlate these features with their epiphytic mode of life. D. crumenatum Swartz and D. anosimum Lindl var. dearei possess similar anatomical features namely: hypostomatic leaf; paracytic stomata, collateral vascular tissue arrangement in stem, presence of bundle sheaths at the leaf and stem, thick velamen, presence of intercellular spaces and water storage cells in the stem and root. These similarities are also seen when compared to other Dendrobium species already studied. Differences on the anatomical features of the two orchid species are in cell shape, cell wall thickness and number of layers of the epidermis, ground tissue, velamen, cortex and pith
