In some Camellia classification literatures

C. longgangensis

C.ptilosperma and C.longruiensis were treated as synonyms of C. flavida

and C.quinqueloculosa

C. longgangensis var.patens

C.multipetala and C.wumingensis were treated as synonyms of C.flavida var.patens

the taxonomic status of these species was discussed in this paper. The morphological characters of flowers

fruits

seeds and leaves in the 15 populations of these species were studied.According to the similarity of the characters

15 populations were divided into three classification groups. Based on the data of prominent classificational characters including corolla tube height

characteristics of flower color

locular number of ovaries

pericarp thickness

with indumentum of the testa of seeds or not

the correlation between the texture and the thickness of the leaves with the lateral nerves

etc

the morphological variations of samples from three groups were compared and analyzd. The results are as follows: The prominent classificational characters except locular number of ovaries among three groups show significant differentiations. Therefore

these species reduced as synonyms of C. flavida are unreasonable. After examining the type specimens and the original literatures

the authors suggest that C.ptilosperma and C.longruiensis are treated as synonyms of C. longgangensis

and C. longgangensis var.patens and C.multipetala are treated as synonyms of C.quinqueloculosa; both and C. wumingensis should be regarded as three independent species.
