| Notes | In order to confirm the taxonomic status of a new variant C.sinensis var.niaowangensis,the comparisons of pollen morphology for 9 samples （6 C.sinensis var.niaowangenis,1 Doupengshan Camellia,1 Jiangbi Camellia,and 1 Fuding Camellia） were observed under SEM.The results showed that：firstly,the main characteristic of pollen morphology of 9 samples belonged to tribute tea C.sinensis with single pollen grain,3-lobed sub-spheroidal in polar view,and reticulate pollen exine sculpture.Secondly,the characteristic of pollen morphology for 6 C.sinensis vat.niaowangensis belonged to wild original shrub or arbor,2 Camellia samples in Doupengshan and Jiangbi with arbor evolution characteristic,and Fuding Camellia with cultivar shrob evolution characteristic.Pollen polar axis length of 6 Yunwu C.sinensis var.niaowangensis was 50.23 to 52.41 micron,exceeded the scope of 50 micron,followed by 2 Camellia samples in Doupengshan and Jiangbi with length of 42.29 to 44.44 micron,and the other Fuding Camellia with length of 45.89 |
