    Two new species of Camellia, C.pubisepala and C. pingguoensis are described from Guangxi (Kwangsi). Both belong to the section Chrysantha H.T. Chang. The golden-yellow flowers of these taxa have very high ornamental and horticultural value.

    酮(Xanthone)又称苯骈色原酮,是一类黄色或无色的酚性化合物,具有与黄酮类(Flavonoids)相似的颜色反应及色谱特性,因此曾被归入黄酮类讨论,但从其光谱特征看酮与黄酮是有区别的。 酮类主要分布于龙胆科(Gentianaceae)、藤黄科(Guttiferae)、桑科(Moraceae)和远志科(Polygalaceae)。但有一特殊例外:芒果甙(mangiferin-2-C-β-D-毗哺葡萄糖基-1,3,6,7-四羟基酮)不仅广布于被子植物的漆树科、藤黄科、豆科、山榄科、大风子科、百合科、鸢尾科、禾本科等,而且在蕨类植物的水龙骨科(Polypodiaceae)中也有发现。

    The purification of protoplasts from cellular and subcellular debrids by floatable washing method with a modified centrifuge tube is described. In this method a modified centrifuge tube, which possesses opened narrow and short tube at the bottom, is used. The yield of protoplasts is relatively high by means of this purification method. The average numder of protoplasts obtained from the stems of corn (Zea mays L.) was 6.2 x 10^5 gm^-1 fresh weight. The average number of protoplasts obtained from the leaves of Petunia hybrida Vilm. was 2.7x10^6 gm^-1 fresh weight. After purification the viability of plant protoplasts is high. During progress the protoplasts were cultured cell division of corn stem protoplats was observed. Cultured protoplasts of Petunia leaves underwent cell division and developed into calli. After the calli were transferred onto differential medium the roots grew.

    In 1976,six hundred green pollen plantlets from F1 hybrids of rice were obtained by anther culture with an average induction-frequency of 5%. Spontaneous doubling diploids among grown plants was about 50%. Between the spontaneous doubling plants (H1) grown in greenhouse and its progenes (H2) grown in field, significant relation in heading date (n=37, r= 0.714), no significant relation in grain weight (n = 37, r = 0.301), and no relation in fertility were found. This figure related partially to the more or less confusion in ploidy level of H1 pollen plants.

    Panisea, a small orchid genus of about nine species known, is confined to the northern parts of tropical Asia, mostly to Indochina and the Himalayas.In China, the first record of this genus was in 1924 by R. Schlechter, who published a new species from Guizhou Province. It was not until 1976 that another species, P.bia, was reported from Yunnan Province (Iconographia Cormophytorum Sinicorurn V). However, the second one is in fact quite different from true P.bia of Laos, as proyed by a comparison with the type specimen (Kerr 0971) at Kew. Instead it is an undescribed species. In addition, in the preparation of an account of the genus Panisea for the forthcoming "Orchid Flora of China", two more species, including a new one, are detected. Thus,there are now altogether four species in China.

    We analyzed the oils from the seeds or fruits of 100 species of the Chincse plants which belong to 71 genera of 41 families. Their contents, refractive index, specific gravity, saponification value, acid value, and iodine value were examined. The quantilative determination of fatty acid was also made by means of GLC. According to the results of the experiment, the percentages of various saturated fatty acids, unsaturated fatty acids, and uses of oils in Compositac, Styracaceae, Oleaceae, Theaceae, Lauraccae and Guttiferae were mainly discussed in this paper.

    During the course of a study on the resupinate Aphyllophorales of China in 1963-1965, a lot of specimens collected from 18 provinces in this country by colleagues of the Mycological Department of our Institute were examined by the present author. In this paper, 5 families, 20 genera and 67 species of resupinate Aphyllophorales are reported. Of which, 5 genera and 42 species are considered to be new records to China. Among these new records, l6 species had already been cited in the late Professor F.L. Tai's work entitled "Sylloge Fungorum Sinicorum" (1979), although no descriptions were provided. All new records, including the 16 species discussed above are briefly described for the first time in this paper. Keys to the families, genera and species, as well as synonyms and distribution of all species are given. Scanning electron microsco-pic photographs of some new records are also presented.
