VEGETATIVE MORPHOLOGY AND LEAF ANATOMY OF CATOPSIS (TlLLANDSIOIDEAE: BROMELIACEAE)

摘要

Members of Catopsis were examined for taxonomically useful morphological and anatomical characteristics related to leaves. External features included rosette shape, leaf size and shape, presence of epicuticular wax, abundance and character of trichomes, and ratio of trichomes to stomata. Leaf anatomical characters included arrangement of stomatal-complex cells, thickness of water storage tissue, and features of the vascular bundle sheath. In general, leaf morphology and anatomy were found to be similar across all species of Catopsis. A number of the characters are associated with habitat preference and thus presumed to be of ecological and ecophysiological significance, but of little taxonomic value.
