摘要
灌木,高5米;嫩枝无毛,红色。叶互生,叶柄长6—12mm,叶片厚革质,椭圆形,长10—16cm,宽4—6cm,先端渐尖,叶基部一般阔契形或略钝,无毛,有微小黑腺点,边缘有细齿或只上半部有细齿,齿刻相隔3—8mm,侧脉7—9对,干时主脉上下突起。花1—2朵,顶生或腋生,直径可达9cm;无梗。苞片和萼片不分化,共15片,革质,背被绒毛,由外至内渐变大,最外1片长2mm,宽3mm,最内2片各长1.5—2cm,宽1.
Camellia multibracteata Chang & Z. Q. Mo is a new species. Its karyotype was studied. According to the classification systems given by Le-ven et al (1964), the karyotype formula of the species is K(2n) = 30 = 16m+ 2m(SAT) + 9sm + 3sm(SAT).
