[A SEM observation on taxonomic and pharmacognostical identification of genus murraya produced in China].

OBJECTIVE
To Observe the morphological characteristics of the leaf epidermis of 9 Chinese species of genus Murraya and prepare and index for their differentiation.


METHOD
SEM(scanning electron microscope).


RESULT
Sect. Murraya was found having with blurred dividing lines on epidermis without ropy emblazonry, while sect. Bergera appeared the other way round.


CONCLUSION
M. kwangsiensis var. macrophylla should be ground under Sect. Murraya as a new species, while M. tetramera should be separated from M. euchrestifolia; SEM has been proved very useful in the identification, taxonomic and pharmacognostical study of Murraya.
