We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips, and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone, and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem, and rays are rather rich in secondary xylem
結果表明：氣生不定根具有以下結構特徵和發育特點： （ 1 ）根為二原型，側根正對著木質部發生； （ 2 ）幼根內皮層細胞具凱氏帶加厚，維管柱內緊挨中柱鞘內側具有2 ~ 4層大型薄壁細胞； （ 2 ）根中無髓和樹脂道； （ 4 ）次生結構發生於根毛區，維管形成層由初生木質部和初生韌皮部之間的薄壁細胞轉化形成； （ 5 ）中柱鞘和栓內層細胞富含單寧類物質； （ 6 ）次生韌皮部有石細胞，次生木質部射線發達。 -
1. the study of comparative anatomy on the structure of seedlings of acorus tatarinowii and zantedeschia aethiopica suggested a. tatarinowii was more primitive " x " - shape mesarch haplostele, while z aethiopica atactostele ; the actinostele of root of the former was di - to octoarch, but the latter only di - to pentarch ; the pattern of endothecial wall thickening in a. tatarinowii was characteristic of five - face thickened and contained passage cell, while z. aethiopica four - faced thickened and known as casparian strip
通過對石菖蒲和馬蹄蓮幼苗結構的比較解剖學研究，發現石菖蒲幼苗的子葉節區下部為原始的中始式二原型的「工」字形的單中柱，而馬蹄蓮為散生中柱；石菖蒲根的維管柱為2 - 8原型星狀中柱，馬蹄蓮為2 - 5原型星狀中柱。石菖蒲根的內皮層細胞壁為馬蹄形五面加厚；而馬蹄蓮為凱氏帶四面加厚。 -
