    The best medium to grow immature sunflower (Helianlhus annuus L.) cmbryos is the B, basic mcdium among MS (Murashige and Skoog, 1962), White (1963) ,B5 (1968) and Nitsch (1969) media used in our experiments. When NAA is cmployed in the immature sunflower embryos cultured in vilro, it promotes embryonic growth of the immature embryos mainly. When IAA und KT are used in combination in immature embryo culture, they have considerably regulative actionl the lower proportion of KT/IAA lnakes young embryo grow roots only while the higher proportion grow buds. Similarly, nature plant extract apparently promotes development and growth, globular embryo of sunflower can normally grow into sceedling in the medium supplemented with Bi Qi (water chestnut) Juice.

    In this article authors have compared carbohydrate contents in secon-dary sink (stem+ leaf sheath) of rice grown at three different altitude localities under the same variety is used and conditions of the same soil, basal and top dressing. The fesults showed that all the contents of total sugar or starch in secondary sink increase as the raising altitude during the +full heading time and the yellow ripe stage. As compared with the full heading titue, their contents increase at the high-altitude,localities, but deerease at the low-altitude localities, during the yellow ripe stage. At the full heading time the starch contents in secondary sink decrease as the increasing dose of basal dressing with nitrogenous fertilizer. At the yellow ripe stage the starch contents in secondary sink of each treatment increase as the increa-sing dose of basal dressing with nitrogenous fertilizer in the warm-cool rice belt. The starch contents in secondary sink of rice tend towards conformity at the low-heat localities, as comparcd with each treatment at different localitieS, however, all the increases of starch contents in secondary sink are due to raised altitude.

    Camellia is a genus with many specics complexes interlocked each othcr.There are four subgencra and twenty sections in Professor Chang Hung Ta's (1981) phylogenetic system of Camellia. Based on the system, this paper furtherly discusses the basic principles guideing the classification of Camellia into fewer taxa and the phylogenetic relationship among them. Then Camellia is suggested to distinguish into two ancestor groups, four subgenera, ten groups and twenty sections.

    Qiongzhuea is a genus published several years ago. There are 8 species and 1 form in the genus which have been found up to now in China. This genus is endemic to China. The concept of the genus and its relation with the neighbouring genera were discussed. The authors believe that Qiongzhuea, because of its inflores- cence, the culm-node without any aerial-spines ring, its turion season, and the plant chemistry characteristics, is a natural taxon and it is different from the genus Chimonobarnbusa. A key to the spceies of the genus was given. A new species and a new form named as Qiongzhuea intermedia Hsueh et D.Z. Li and Qiong-zhuea macrophylla f.leiboensis Hsueh et D. Z. Li were described respectively.

    The present paper recognized that according to the morphology comparison autoallopolyploid Sequoia sempervirens with genomic formula AAAABB[3] may originate from the hybridzation between romeone ancient species of Metasequoia and Sequoiadendron which were the parents. Metasequoia glyptostroboides and Sequoiadendron giganteum were direct descendants of the parents probably, which proyided gcnomes AA and B for S. sempervirens res- pectively.The concluson was the same as that based on the karyotypic data[19], but did not agree with Stebbins' inference that another ancestor,except Metasequoia, was extinct and did not left any close relatiyes.

    Yuanmou river valley is situated in the north-central part of Yunnan plateau. It is one of the most dry and hot river valley in Yunnan province. The vegetation of the valley is somewhat like the "savanna" of tropics. The flora below 1600 m of the valley has been studied in this paper. There are 78 families, 266 genera and 399 species appearing in the valley flora. Large number of tropical plantr, (specially the savanna elements are found in this area. The floristic com- position of the river valley and its relationship to the flora of neighboring district, the India savanna, have been discussed.

    Lastly, works haye been done in the comparative study on the features of physiognonly and structure with tropical cquatorial rainforest. The discussion and comparison show that the floristic component of the forest oil horizontal distribution there are some species are the preyalence everywllere, others due to the cvolution and spread of specics, new species cvolve, old species die out or come to occupy more rcstricted areas, and according as the different local geo- morphy, soil, climate are formed diversity society, from the further constituted mosaic. these society and mosaic in the same a forestland are striking too. The vertical structure of forest consists of the seven layers in natural forest, and the species of structure each layer, D layer is more than others layer of which appears that have the major independent charactcr interlayer relationship. The trees layer, the shrubs layer, the herbaceous layer and the grounds layes are fundamental synusia and they make up the skeleton in forest structure.
