Classifying Taiwan Lianas with Radiating Plates of Xylem

摘要: Radiating plates of xylem are a lianas cambium variation, which, 22 families have this feature. This study investigates 15 liana species representing nine with radiating structures. The features the transverse section and epidermis in fresh samples documented, including shapes colors phloem, ray width numbers, skin morphology. Experimental results indicated that shape phloem fibers ＂Ampelopsis brevipedunculata＂ var. ＂hancei＂ is gradually tapered flame-like, which contrast other characteristics type, those classified as rays. Both inner outer cylinders vascular bundles found ＂Piper kwashoense＂, irregularly cylinder persists yet diminishes. Red crystals numerous cortex ＂Celastrus kusanoi.＂ ＂Aristolochia shimadai＂ ＂A. zollingeriana＂ develop combination two variants, lobed xylem. ＂Stauntonia obovatifoliola＂ square or truncate, its rays numerous. Meanwhile, ＂Neoalsomitra integrifolia＂ blunt fewer. As for stem surface within same family, ＂Cyclea ochiaiana＂ brownish color has deep vertical depression lenticels, ＂Pericampylus glaucus＂ greenish shallow depression. Within genus, develops not zollingeriana＂; although periderm developed ＂Clematis grata＂ ring bark tears easily, tamura＂ thick soft.
