[Morphological and histological studies on Aralia plants].
OBJECTIVE
To make clear the descriptions and microscopic histological structures of the roots, stems and rootstocks for twelve species from Aralia plants.


METHODS
Observing the descriptions and histological characteristics.


RESULTS
The histological characteristics of the various species are basically identical. Each of them equally contains cluster crystals of calcium oxalate and starch grains; secretory canals exist extensively in the cortexes, phloem and piths; neither cortexes nor phloem of roots have thick-walled cells, but cortexes and phloem of the stems of the wood plants have fibers or stone cells.


CONCLUSIONS
The pharmacognostic and interspecies characteristics for wood and herbaceous plants identification were obtained. The wood and herbaceous plants in one natural group of a genus as its two subgenera was sustained by the study result.
