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) . 。 |

In cucumber , there were obviously si depoist on the older leaves from + si plant , si ca n ' t be observed on the younger leaves from + si plant . there were no silicon distribtion on the - si leaves . by analzing edx map of silicon , it was showed that , in the leaf blades of rices , si exsisted in the form , of fan - shaped and dumbbell - shaped . there were many trichomes which contained si on the surfaces of leave and stems on cucumber 在兩種植物中，水稻表現出老葉硅分布比嫩葉密集，從葉尖-葉中部-葉基部表現出硅分布密集程度逐漸降低的趨勢；加硅處理的黃瓜老葉硅的分布較明顯，但嫩葉和未加硅處理的葉片未見明顯的硅的染色。通過掃描電鏡及硅的x能譜分析顯示，水稻硅呈紡錘體及扇形硅質體。 |

After comparatively researching the morphology , anatomy and development process between carpel and leaf , we put forward a viewpoint that the carpellary disc of paeonia is not from the receptacular projection , but is a appendant organ of carpel . they come from leaf blade and leaf sheath separately . ( 3 ) after researching carpellary morphology and anatomy of nine groups of sect 通過對心皮和房衣與葉子的形態、解剖和發育的比較，認為芍藥屬植物的房衣不是花托上的突起，而是心皮的一個部分，即每個心皮及其房衣可能共同起源于一片完整的葉子，心皮來源于葉片，房衣來源于葉鞘。 |
