    Salvia in China includes 78 species, 24 varieties and 8 for-ms of which 20 species have been studied both by light micros-cope and scanning eletronic microscope. The shapes of Salvia grains are mainly elliptic, spheroidal and oblate with 6 furrows, only few species with more than 6or 15 furrows. According to the research on sculpture of exine, 7 types of sculpture have been divided:shallow reticulum, reticulum with 2 types of size of lumina, two beds of reticulum, deep reticulum, disorderly reticulum, large reticulum with small lumina in it and reticulum with baculum. Based on the sculpture difference, exine thickness as well as furrow shape, structure of furrow bottom and size of pollen grain, these species can be distinguished from each other.

    A numerical taxonomic study on genus Salix L. of China(Ⅰ) is presented. At first, 37 operational taxonomic units(OTU's) were chosen according to 37 sections of Chinese Salix(Wang & Fang et., 1984), each section were represented in it's type species or primitive species (table 1). After removed the correlation and homology among all Salix characters, 32 morphological characters including four deriative characters were employed. Through standardization for original data matrix,we used the coefficients of correlation (rij) and distance (dij)as similarity measure and utilized several cluster analysis methods Being of comparison of the cophenetic correlation coefficient res values, UPGMA method were selected as the optimal one and it's result taked shape phenograms, figure 1, figure 2. On the basis of figure 1 and figure 2, 37 sections of Chinese Salix form seven greater sections. The order from A sectionto G section shows evolutionary process. Particularly, the relationships among 37 sections are our primary results. We found and explained some problems about morphological classification, divided and merged many sections, such as a few of the primitive sections in the A section, 10 Sect. Floccosae Hao and 11 Sect. Lindleyanae Schneid., 22 Sect. Hasatatae A.Kern. and 23 Sect. Arbuscella Ser. ex Duby, 7 Sect. Fulvop-ubescentes C. F. Fang and 25 Sect. Lanatae Koeh., 14 Sect.Eriocladae Hao and 9 Sect. Denticulatae Schneid., 8 Sect. Magnificae Schneid., and so on. On numerical method, we discussed and evaluated the distance coefficient. The combined line (Xu et., 1983) were satisfactorily applied to divide the taxa.

    The development of the endosperms of Trillium begins in the chalaza end. The first division of the cndosperm nucleus is accompanies by the formation of a horizontal wall which divides the embryo sac into two, usually unequal, chambers of which the micropylar one is larger than the chalazal. This is followed by several nuclear divisions in the micropylar chamber where the resulting nuclei remain free, while in the chalazal chamber the nucleus does not divide or occurs a few of divisions. In the course of further development, the nuclei in the chalazal chamber begin to disintegrate. Cell walls may appear in the micropylar chamber. Hence, the endosperm of Trilliumis of Holobial type.

    The genus Athyrium is a larger one in the class Leptos-porangiatae. There are about 300 species which mainly distribute in the warm temperate zone of the world. In the region of southwest China, Himalayas and Japan, there are more species than in other regions and the morphology of plants and the shapes of the sori here are various, so it is difficult to classify them. The auther of this paper classifies the genus Athyrium into two subgenera which include five sections and ten series, according to the characteristics of rhizoma (creeping, erect or adscending), the degree of frond pinnation (pinnate, bipinnate or tripinnate), the shapes of scales, the hairs types, whether there are spines on the rhachis of fronds, pinna and pinnules or not,the types of serrature, spores morphology. At the same time,the characteristics of venation (catadromous, anadromous or opposite), the shape of sori and whether the sori have indusia or not and their shapes, etc. are used.

    Based on a study of the type specimens of Sedum algidum Ledeb. var. tanguticum Maxim. (=Rkodiola algida (Ledeb.) Fisch.et Mey. var. tangutica (Maxim.) Fu), the var. tangutica should be a different species from Rhodiola algida. The two species may be summerized as below:Rhodiola algida:Flowers usually bisexual, sometimes with pistils obsolete; petals linear-lanceolate; stamens distinctly shorter than the petal. Distr. Altai region of China(?), USSR and Mongolia. Rhodiola tangutica:Plants dioecious, or occasionally with bisexual flowers(?):petals narrowly linear; stamens longer than the petals. Distr. Gansu,Qinghai and Sichuan (Dege Xian).

    Whether the Pinus koraiensis plantation can keep the in-organic activity balance and its steady growth, except the weather condition, depends mainly on the amount of litters' nutrient elements turned back into the soil every year. The purpose of this paper is to find out various laws of the litter change, and in order to improve the plantation condition as well as establish the best structure of typical stand we provide scientific basis here so that the maximum increasing of production per unit area may be appear. This experimental material is from the result of periodical observation during 1980——1984 in the Pinus koraiensis plantation of 26 years old, which is within the Laoshan experimental plantation station in Maoershan of Shangzhi County in Heilongjiang province. The litter's of Pinus koraiensis come from needle leaves,needle leave branches, needle leave bark, flowers, fruits, bud scales, birds' excrement, etc. ……. The average dry weight of five years is 1701.6kg/ha.; The amount of nutrient elements of various litters are evidently different. The contents in leaves is the highest and the least in leaf sheathes; The average amount of nutrient elements (N, P, K, Ca, Mg, Cu, Fe, Mn)turned back into the plantation floor is 32.78kg/ha.
