Comparative stem anatomy of four taxa of Calycanthaceae Lindl.
Abstract
The anatomical character is potential value in Calycanthaceae for their taxonomic study. Four species of Calycanthaceae were collected for this experiment. The experiment was done using the resin methods for preparation of the permanent slide for anatomical studies. The anatomical character like two traces of the unilocular vascular bundle, in the primary vascular cylinder, contains four cortical vascular bundles in the stem, the unilocular structure of primary cylinder, the presence of numerous intercellular space in phloem, the presence of oil cell in the form of scatter in Calycanthus whereas small size in Chimonathus. Calycanthus possess boarder pit with circular aperture while Chimonanthus possess elliptical. The tracheid is a characteristic feature of the spiral band wider in Chimonanthus than that of Calycanthus and Sinocalycanthus. The noted sclerenchymatous cells are grouped of the colony which is a characteristic feature of Sinocalycanthus and Calycanthus but in case of Chimonanthus is the long chain with the layer of the cell. Collenchymatous cell was circular with an intercellular in Calycanthus; ovoid shape with the intercellular in Chimonanthus but in Sinocalycanthus is elongation with the minor regular shape. The different character of pith cells found in hexagonal and circular shape which is also distinguished feature in Calycanthaceae. The valu-able stem anatomical characters are the importance of their function, ontogeny, and phylogeny.
