simple leaf 【植物;植物學】單葉。

simple past

2 comparative study on morphology in the light of the form of the materials , hup shows more approximate relationship with gri : they are 50 ~ 70cm high at the period of fructescence ; both are perennials and reproduce themselves by root stock , and especially , hup can also reproduce itself by branch roots and buds growing from stipes when the stems fall againt the ground , and then those buds develop into new bodies ; while gri can reproduce itself not only by vegetative propagation but by seeds . both of hup and gri characterize with bigger leaf blade and with the approximate form of simple leaf , with root stock , and with two - line seeds in one fruit 2形態學比較從形態上來看,新種hup與分布海拔高度相近的gri比較接近:植株體高大,果期株高50一7ocm ;都為多年生,能以其根狀莖繁殖,但前者還以較為特殊的營養體繁殖后代,即倒伏后每個莖節上長出新的根和芽,發育成獨立的新植株,后者既能以營養體繁殖,又可通過種子繁殖;具有較大的葉片且單葉形態相近,果實內有二行種子(其它種為一行) . 。
