Development of Morphological Descriptors of Some Orchid Species

Abstract

Amongst different morphological descriptors of commercially grown orchid genera, diversity in pseudobulb shape, leaf shape, inflorescence variation, and floral characteristics was studied in detail. Morphological descriptors of 42 orchid species namely Acampe rigida, Acampe papillosa, Aerides rosea, Arachnis labrosa, Arundina graminifolia, Ascocentrum ampullaceum, Calanthe masuca, Cattleya maxima, Coelogyne elata, Coelogyne flaccida, Coelogyne fuscescens, Coelogyne nitida, Coelogyne ovalis, Coelogyne suaveolens, Coelogyne orchracea, Coelogyne graminifolia, Coelogyne cristata, Coelogyne barbadense, Cleisocentron trichonum, Cottonia peduncularis, Cymbidium cyperifolium, Dendrobium nobile alba, Dendrobium farmerii, Diplomeris hirsuta, Epidendrum radicans, Epidendrum secundatum, Epidendrum xanthium, Eria bambusifolia, Eria coronaria, Eria flava, Eria suaveolens, Gastrochilus bellinis, Lycaste cruentus, Lycaste macrophylla Paphilionanthe vandarum, Paphiopedilum spicerianum, Phaius flavus, Phaius wallichii, Phalaenopsis mannii, Renanthera imschootiana, Thunia marshalliana and Vanda motesiana developed which could be useful for identification of unique germplasm for pot plants, medicinal orchids, breeding materials and preparation of value added products.
