COMPARATIVE LEAVES ANATOMY OF PANDANUS, FREYCINETIA AND SARARANGA (PANDANACEAE) AND THEIR DIAGNOSTIC VALUE
ABSTRACT: Study in leaves
anatomy of twenty nine samples of the species classified under Pandanus,
Freycinetia and Sararanga of Pandanaceae had been undertaken to unravel generic
relationship among of these taxa with a view to provide a set of diagnostic
characters for taxonomic identification. The fourth genus of Pandanaceae,
Benstonea is not included in this analysis since there are no representative
samples. Four anatomical diagnostic characters had been identified at the
generic level such as present and absent of papillae, stomatal arrangement types,
present and absent of bundle sheath extension and hypodermal thickness and its
shape. Pandanus has papillae, amphistomatous stomata, bundle sheath extension
present and hypodermis thin and rectangular; Freycinetia lacked of papillae,
stomata hypostomatous or amphistomatous, bundle sheath extension absent and
hypodermis thick and hexagonal or rounded; meanwhile Sararanga has no papillae,
stomata amphistomatous, bundle sheath extension absent and hypodermis thin and
flatten. An identification key to those genera based on anatomical diagnostic
characters is provided.
