    Psammosilene tunicoides W. C. Wu et C. Y. Wu is a famous medical herb in Yunnan province. It is usually used as anodyne and haemastatic. The saponins are abundant in its root and possess physiological activities of analgesia, counteracting inflammation, bactriostasis. Two new oleanane type-triterpene glucosides I and II were isolated. Their structures were determined as 28-β-D-glucopyranosyl( 1-3 )-β-D-glucopyranosyl( 1 - 6 ) -β-D-glucopyra-nosyl-3α, 16α-dihydroxy-12 ene-23-dioic acid and 28-β-D-glucopyranosyl 1-6 [β-D-glucopyranosvl l - 3 ] -β-D-glucopyranside-3α, 16α-dihydroxy-12-ene-23-dioic acid, respectively. The two saponins and their sapogenins are all new natural compounds.

    Yanhusuo, the dried tubers of a species affiliated to Corydalis remota Fisch. ex Maxim., is one of the most famous Chinese herbal drugs frequently used as an analgesic in this country. The taxonomical treatment of Yanhusuo has been very confused and difficult because of the wide variations of its morphological features. However, the isoquinoline alkaloids in the above plants were found to be qualitatively and quantitatively different. The aporphinc type alkaloids such as glaucine were found in Yanhusuo while corynoline type alkaloids found in C. remota. These results can be used to differentiate them each other, even by a simple authenticated TLC chromatogram described in this paper. Therefore, it is more rational to consider that Yanhusuo as an indepen-dent species Corydalis yanhusuo W. T. Wang ex Z. Y. Su et C. Y. Wu than as C.turtschaninovii Bess f. yanhusuo Y. H. Chou et C. C. Hsu or others.

    This paper is a continuation of the previous one which has been dealing with a numerical taxonomic study on the variation patterns on popula-tion level of 5 species of Mosia (Labiatae) in the same region.In the prev-ious paper, we have come to the conclusion that the 5 species of Mosia had differentiated into two main phylads in its early stage of evolution. In the present study, the essential oil extracted from the same species was analysed by means of a gas chromatograph-mass spectral in order to reveal the phylogenetic relationships of the said species on chemical level.

    Gloriosa superba is a herbaceous plant of Liliaceae, the tuber contains colchicine. In the present paper the tuber formation and change of substance in tuberization are described. The results are briefly summarized as follows: 1. After sowing of tuber, the growth of tuber was slow in the early and later growing stages, however, growth of tuber was the fast in the interme-diate growing stage, it also was main stage of tuberization. 2. The nutrition substance in tuber was mainly starch, the starch content in new tuber increased gradually from sowing to ripeing stage. 3. The photosynthetic rate and leaf area were increased gradually after the sowing of tuber, and before flowerring, they reached maximum and gradually slow down afterwards. 4. The colchicine content in new tuber increased with ripeness of tuber and increasing of starch content, it reached the maximum at ripe stage. The results showed if unripe tuber was harvested, the colchicine content was lower than that of the ripe tuber.

    Seeds of parasites of Loranthaceae have no dormant period. They can germinate within fruit, but their germinating vigour are affected greatly. The effect varies with time length and species of the parasites. Pulp has some impact on its seed germination. Gemination rate as well as cotyledons and leaves appearing rate of seeds without pulp are higher than those of seeds with pulp. Germination and cotyledons appearing rate of seed in the dark is lower than those of seeds illuminated, and seedlings of the former are yellowing, spindling, and not well. Seeds reguire high temperatures to germinate. It takes 2-8 days to begin germinating and germination rate is 93.6 at room temperature (18-32 °C).While at lower temperatures ( 4 - 5 °C), 10-31 days are needed to start germinating, and germination rate only 78 . And the seeds of one or two species even can not germinate. Lower temperatures produce great impact on the vigour of germinating seeds. When moved from lower temperature to room temperature, most of seeds are died in a short time, Under suitable condition of temperature, humidity and light, seeds of the parasites can germinate on every kind of living or dead bodies or substances without any man-made substratum. Their total average rate of germination is as high as 87.3, and hostoroa, cotyledons and leaves can be formed. It is short from sowing to germinaring. To most of seeds, it is within one week. These features are closely related with the plump endosperm, abundant nouri-shment stored in seed. Glutinous substances covering seeds, which prohibits water loss, green seeds undertaking photosynthesis while germinating, seeds without dormant period and mature embryo germinating within a short time also have closely relations to seed germination and seedling growth.

    Abstract The present paper deals with the classification on the genus Neobarbella. A key to species is described. This genus consists of 4 species, of which 1 species is new, it occurs only in southeastern Asia. N. pilifera widely distributes in East Asia. N. comes is a Sino-Himalayan species, but extending to Philipoines and Indonesia. N. amoena and N . serraiiacuia are endemic species, the former only distributed in Ceylon, another one in China. The morphological characters of N. pilifera and N. comes seem to be comparatively similar each other their branch-leaves are different from stem-leaves. While in N .amoena and N.serratiacuta, their brach-leaves are similar to stem-leaves. All of the species of the genus Neobarbella, the secondany stems usually hanging, long, pinnately branched. The cells of the central tissue are large and thin-walled.

    Ten Species of Dysoxylum Bl. were recorded in Yunnan, China including several endemic species, but some species have not yet been recorded. Based upon a comparision of specimens collected from Southern and Southeastern Asia, and studies of relevant data, one new record, Dysoxylum densiflorum (Bl.) Miq. is confirmed in Yunnan.The uniting of species: Dysoxylum s pica-turn into D .binectariferum, D. hainanense into D. mollissimum, D.gobara into D.excelsum is suggested. The supplemental morphological descriptions for some endemic species are added in this paper as well.

    Pollen analysis of five surface samples on Liangwang Mountain of Chenggong (N24°57',E102°37') provides information about the quantitative pollen-vegetation relationship for major plant taxa. Vegetation data with coverage are estimated from each sampling site within the range of 20m. Acorrding to the difference of R-values, the pollen types could be divided into two groups: 1. R> 1 .over-represented, the type containing Pinus, Ainus, Coriaria, Artemisia and some ferns; 2 . R< 1 , under-represented, the type containing Keteleeria, Castanopsis+Lithocarpus, Cyclobalanopsis Quer-cus, Myrsine. The pollen deposition of Pinus is dependent on the pollen production and on the wind velocitie and wind direction in the April-May flowering seasons. The west wind is mainly reason to affect distribution of Pinus pollen.

    The present paper deals with the cytogeographic study of 3 species on the genus Remusatia, Araceae. Their karyotypes can be formulated as followings: Remusatia vivipara (from Mt. Cangshan, Yunnan) K(2n) = 3X =42= 42m; R. hookeriana (also from Mt.Cangshan, Yunnan)K( 2 n) = 2X= 28 = 22m (6SAT) + 6sm ( 2 SAT); R. ornata (from Mt. Shizishan, Wuding Xian, Yunnan) K ( 2 n) = 3X = 42 = 36m (3SAT) + 3sm + 3st. In the genus Remusatia, R. vivipara is primitive and R. ornata is evolutional. Remusatia is a minor genus which distributes both in tropical Asia and in tropical West Africa (Came-roon) . In South India (Kerala) the population of R. vivipara is diploid. And we conclude that the origin site of the genus Remusatia is Gondwana Land. The dispersal of the genus Remusatia towards tropical Asia would be related with the Himalayan movement.

    The precent paper reports the chromosome numbers and karyotype analysis of Paeonia obovata Maxim., P. delavayi Franch. and P. delavayi Franch. var. lutea Finet et Gagnep., which were collected from Jiangxi and Yunnan Province of China. On the chromosomes of these species, it is show a similarity that the somatic chrosome number of all species are 2 n = 10, their karyotype formulae are 2 n= 6 m+ 2 sm + 2 st. In these species, however, each species may be distinguished from anothers by number and position of secondary constriction. The P. obovata has two pairs of SAT-chromosome, the secondary constriction are on the short arm near terminal of 4 th and 5th pairs. The SAT-chromosome of P. delavayi and P. delavayi var. lutea both have 3 pairs. 4th and 5th pairs of these as similar as P. obovata. But there is one secondary constriction on the long arm near centromere of 1st pair of P.delavayi, one on the long arm near centromere and another on the short arm near terminal of 2nd pair of P. delavayi var. lutea.

    Taxodiaceae Warming consists of 19 species belonging to 9 genera (excl, Sciadopitys), of which 5 genera and 11 species are endemic to China and its neighbouring regions. The cytolpgical studies on the family were initia-ted in the early years of this century. To-date, karyotypic analyses for most of the genera(excl.Athrotaxis) have been made.The karyotypes of them:that of Cryptomeria,Glyptostrobus,Taxodium(T. mucronatum, "2A"), Metase-quoia and Sequoia semperuirens-AA belong to Stebbins' (1971) "1A" type of karyotypic asymmetry; that of Sequoiadendron, Cunninghamia and Sequoia semperuirens-B to "1B"; Taiwania to"2B".The type "1B" may be a new one in higher plants beacause it has not been found (Stebbins 1971).
