弓形的

Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls. Stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all Species. The slomata apparatus mainly belong to the paracytic type and latercylic type; rarely anomocytic type occurs along with the paracytic one.

结果表明：这些植物叶片的上、下表皮细胞呈多边形或不规则形，垂周壁式样为平直、弓形或波浪状，平周壁偶有脊状条纹；少数种类上表皮还有气孔器或分泌细胞，所有种类下表皮具气孔器和分泌细胞；气孔器类型以平列型和侧列型居多，偶尔有无规则型；气孔极区呈稍角质加厚或棒状加厚，稀T形加厚。

The results showed that leaf epidermal cells were polygonous or irregular in shape. Stomatal complexes only present on abaxial epidermis and the stomata was paracytic type. There were five types of anticlinal walls of abaxial and adaxial cells (straight, rounded, undulated, sinuous, straight-curved). Trichomes on abaxial epidermis exist or not. Ornamention types of periclinal walls could be divided into punctuate, smooth and striate. Ornamention of periclinal walls on inner side of abaxial epidermal cells varied widely (irregular, smooth, roughly reticular, micro hairy, granular, scaly).

结果表明：润楠属植物叶表皮细胞形状为多边形或不规则形，气孔复合体均为平列型且仅分布在下表皮；上下表皮细胞的垂周壁式样有5种类型：平直、圆滑、浅波、波状、平直-弓形；下表皮毛被有或无；上表皮平周壁纹饰类型有：点状、平滑、条纹；下表皮内面平周壁纹饰类型有：不规则、平滑、粗糙网状、微毛状、颗粒状、鳞片状。

The results showed that leaf epidermal characters of the genus revealed a remarkable consistency: the leaf epidermal cells were usually polygonal and subpolygonal bearing with straight or arched anticlinal walls; and the stomatal apparatus was mainly anisocytic type and presented in abaxial epidermis of all studied species.

结果表明秋海棠属植物叶表皮形态在属内组间具有较大的相似性，表皮细胞为多边形或近多边形，垂周壁平直或弓形，大多数种类表皮细胞内具有晶体，气孔器仅分布于下表皮，且以不等型为主。
