The bodies of imp are 20 ~ 60cm high at the period of fructescence , which is alike to that of hup and gri ; the other characters are alike to those of hir and scu 分布在中等海拔的imp植株体较为高大，果期株高20一60cm ，这一点与hup和gri较为接近;仅以种子繁殖后代，无根状茎;羽状复叶，叶片较小，且有明显的小叶柄;果实
The bodies of hir and scu are short and small comparing with the two former , 15 - 30cm at the period of fructescence ; both characterized with no root stock , and with small leaf , which is pinnately compound leaf , and with only one - line seeds in a fruit 广布于较低海拔地带的hir与scu植株体相对矮小，果期株高15一30 。 m ;没有根状茎，仅以种子繁殖;叶片较小，均为羽状复叶，且有明显的小叶柄;果实内为一行种子。
With many efforts , the scientists of china have succeeded in researching the plant rapid propagation of many kinds , yet only about ten kinds of economic plants have been industrialized and spread over an extensive area , though in a low speed 而针叶树种有许多植物品种进行组织培养难度很大，基本上不能大规模生产。常规拖插又存在著生根慢、成活率低。致使这些品种的苗木一直在用用种子繁殖，后代性状变异非常大。
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形态学比较从形态上来看，新种hup与分布海拔高度相近的gri比较接近:植株体高大，果期株高50一7ocm ;都为多年生，能以其根状茎繁殖，但前者还以较为特殊的营养体繁殖后代，即倒伏后每个茎节上长出新的根和芽，发育成独立的新植株，后者既能以营养体繁殖，又可通过种子繁殖;具有较大的叶片且单叶形态相近，果实内有二行种子(其它种为一行) . 。
