The wild ancient camellia (Camellia japonica L. ) is distributed on off-shore islands near Mount Lao inQingdao. As the cold-resistant type,it was so-called"Naidong Camellia" by the local people. Accordingto the stable morphological diversity,the Naidong Camellia can be divided into such groups as'long androecium","less petais" ,"grand flower", etc. Naidong Camellia on off-shore islands in Qingdao has attracted much attention not only for the high appreciating value,but also for its being natural gene-poolof Camellia in North China. This paper dealt with the distribution of Naidong Camellia and its presentstatus,some ecobiotic traits and the morphological variation. The siginificance of the studies for NaidongCamellia diversity was also discussed.
