- Anomocytic stomata were confined to the lower epidermis. 气孔器不规则型,仅分布于下表面;
- Some populations have unicellular hairs on lower epidermis. 有的居群下表皮有单细胞表皮毛分布。
- In most plants stomata are located mainly in the lower epidermis of the leaf, where evaporation rates are lower. 气孔和保卫细胞合称气孔器。
- The leaf was two-sided and was composed of upper epidermis, lower epidermis and mesophyll.There had feathery stockwork in the mesophyll. 叶为两面叶,由上、下表皮和叶肉组成,在叶肉中有羽状网脉,具有药用价值。
- The leaf structures of these two plants were basically alike: their epidermis were made up of one layer cells. Stomatas only existed disorderly on the lower epidermis and their arrangement was a irregular type. 两者结构基本相似,表皮均由一层细胞构成,气孔仅分布在下表皮,无一定排列方向,为无规则型。

- On the lower epidermis, bushy trichomes including glandular hairs and non-glandular hairs are observed and some strumaes distributing regularly are hypothesized as oxalic calcium. 同时在下表皮还分布有瘤状的草酸钙簇晶。
- The value of stomatal conductance was higher on lower epidermis than upper one, and the stomata of low epidermis were more sensitive to the environmental condition. 乾旱季节上下表皮气孔日间开启程度不同,下表皮气孔受环境因子的影响较大;湿润季节则相同。
- The studies show common features among them such as the stomata which is found in the lower epidermis, the wavy anticlinal walls of the epidermmal cells and the cyclocytic stomatal type. 结果表明,其间存在明显共性:表皮构造均为单面气孔式,上下表皮细胞垂周壁皆呈不同程度的波状起伏,气孔器类型皆为环列型。
- The olive leaf is a badge of peace. 橄榄叶是和平的象征。
- Why is it so hard to be like the rest of the flock, Jon Why can't you leave low flying to the pelicans, the albatross Why don't you eat Jon, you're bone and feathers! 为什么你不能把低空滑翔的事留给那些鹈鹕和信天翁呢?为什么你不去觅食。乔仔,你现在已经瘦的“毛包骨头”了!
