(1 )麻黄茎的初生结构与被子植物茎的初生结构相似 ,但在靠近表皮的薄壁组织中有许多束状厚角组织排列成一环。(2 )草麻黄的纱叶结构简单 ,无栅栏组织和海绵组织的分化 ,在叶片叶肉组织中仅有两束维管束(3)草麻黄茎节部有许多维管束斜向伸入叶内 ,分为两束。这种维管束斜生于茎内的部分 ,称为叶迹。在茎的维管系统内 ,位于叶迹的近轴处 ,由薄壁组织所充满。 (1) The epiphytic structure of the ephedra is similar to that of the angiosperm stem, but there are many bundles of thick and angular tissue in the epidermis near the epidermis. (2) The leaf structure of Ephedra sinica was simple, with no palisade tissue and spongy tissue differentiation. There were only two vascular bundles in leaf mesophyll tissue. (3) Divided into two beams. This vascular bundle oblique born in the stem of the part, known as the leaf trace. Within the vascular system of the stem, at the paraxial region of the leaf trace, is filled with parenchymatous tissue.
