Ahstract In order to find the aroma characteritics of Valeriana officinalis var. latifolia, the chemical composition of the essential oil of this plant have been examined. This essential oil was analysed by GC-MS on the Finnigan -4510 instrument. As a resu1t (see Tab1e 1 and Fig. 1 ) 21 compounds were identified. The major components are bornyl acetate (50.56 % ), α-pinene (6.76% ), camphene (16. 17% ), β-pinene (6. 48% ), limonene (1.77% ), carveyl acetate (5.47% ), dihydrocarveyl acetate (1.62%) etc. This essential oil having a delicious aroma shows to be suitable for compounding perfume of cigar and food flavor, and cosmetic flavor too.

In this review, in nine plants the interrelations of phytoecdysones on their chemical structure and their biosynthetic pathway have been discussed. We propose the general character of C27, C28, C29 phytoecdysones in their biosynthetic processes, which based on the biogenesis of C27 phytoecdysones was expounded, and consider the common biogenetic precursor existed, and suggest the biosynthetic mechanism of some special phytoecdysones, and predict some special new phytoecdysones (Fig. 9 ) possibly existed in the special plant.

From the root of Melasma arvense (Benth. ) H.--M., aucu- bigenin-1-O-β-gentiobioside (2 ), a new iridoid glucoside and hydroxy-β- ionone glucoside (1 ) was obtained. Their structures were establlished by spec- troscopic analysis.

In this paper we used data of "the study of physiological--ecological rules on high-yielding culture of rice in the plateau", of which are obtained from the field plot experiments of rice grown at Yuanjiang (dry--heat river valley about 400 m altitude), Kunming (warm-cool plateau lake-shore about 1900 m altitude), Lijiang (cold-cool plateau area about 2400 m altitude), Yunnan, respectively, from 1983 to 1985. The total tendency of dry-matter production and partitioning in the aerial part of rice grown at different altitude localities was compared, based on the total mean value of six treatments in eighteen plots for three years, The main results are as followst.

Ahstract Erythroagglutinin components (E2-SML) are purified from Snow Mountain Bean Lectin (SML) by ion exchange chromatography on SP-Sephadex C-50 and Phosphocellulose column They are monitored by polyacrylanlide gel clectrophoresis analysis and hemagglutinating assays. The cathodal proteins (E2 -SML) are potent hemagglutinins With hemagglutination titers 64 and 512 times more potent than SML and L-SML respectively. The methods we used can separate active cornponents of erythroagglutinin lectin in large yield and high purity.

Some precious reports (Yan, Zang, Zhang etc.) concerning the Ganbajun (干巴菌) in Yunnan have been determined as Sparassis crispa (Wulf.) Fr. The uthor subsequently determincd that it was misidentified and is, in fact, it would be nice to place the correct Ganbajun's nomenclature in genus Thelephora and considering it as a new species Thelcphora ganbajun, it might be acceptcd as being more resonable. It appears to be an abundantly characterized the new species, probab1y close to Thelephora robusta Corner, which differs by the hyaline and brownish spores and shorter basidia (25--35 um), however the larger basidia of Thelephora robusta Corner, is often longer than 75-100 um.

Among 56 seedlings with red--colored cotyledons and hypocotyls obtained after hand pollination betweed Camellia pitardii var. yunnanica (hexaploid) and C. chrysantha (diploid), 55 (98.2%) were of true tetraploid-hybrids (X2 = 0.0128, D. f. = 1, 0.95> p >0.90), while among 50 seedlings with yellowish-white-colored cotyledons and hypocotyls, 13(26%) were of true tetraploid-hybrids (X2 = 27.38, D. f. = 13, 0.02> P >0.01). In contrast, among 78 seedlings with red-colored cotyledons and hypocotyls obtained after hand pollination between C. reticuIata (hexaploid) and C. chrysantha, 77(98.7%) were of true tetraploid-hybrids (X2 = 0.0l28, D. f. = 1, 0.95> p >0.90), while among 78 seedlings with yellowish- white-colored cotyledons and hypocotyls, 2l (26.9%) were of true tetraploid-hybrids (Xz = 4l .65, D. f. = 24, 0. 02> p >0.01).

About 71 species of Agaricales, Boletales and Cantharellales are repor- ted by Lohwag in Handel--Mazzetti (l937) from N-Yunnan, China. The bulk of material was collected on the forested slopes of the mountain massif Yulong shan, north of Lijiang, The revision of the authentic specimens yielded the following results: original identification is confirmed for 32 taxa, another 32 species are misidentified; finally the material of 7 records is absent in WU.

Summary 1. In present paper Corydalis Sect. Racemosae Fedde including 3 species and 2 varietes is revised. In spite of it is a small section, but distr- ibuted in a vast regions in China and Japan. 2. Sect. Racemosae Fedde was established by Fedde in Fedde, Repert. 20:62. 1924 and companied with a Key including 6 species (C. racemosa, C. giraldii, C. fumaria, C. handelmazzetti, C.balansae and C.lofouensis). In 1936, he reduced the section into a subsection and placed under Sect. Eu- corydalis Prantl sensu Fedde. Here he added a heterogeneous species C. edulis Maxim. in it and rewrote the diagnosis, in which some inportant characters (e. g. color of flowers) had a mind to be omitted. Fedde's diagnosis is so confused with other short-calcar groups (e. g. Subsect. Strictae Fedde etc. )that he could not make a key for them. (Engler et Prantl, Pflanzenfam. 2 ed.,17b: 129 note 3 ). It should be revised again as in present paper. By the aid of mode of branching, shape of stigma and capsulae it is easy to differ Sect. Racemosae from other short-calcar groups (Subsect. Strictae, Thalictrifoliae sensu Fedde and Sect. Sophorocapnos sensu Popov).

The present paper is a preliminary outcome of taxonbmic study of chinese plants of sect. Cucubaloideae. It contains 3 subsections, 25 species,2 varieties, of which 2 subsections are described as new and 1 belong to new grade. Besides, 6 species, 1 variety and 3 forms have been reduced to synonyms. The chinese plants of section Cucubaloideae in Silehe are mainly distributed in the Southwest, the Northwest, passing along the Central to the Northeast China. Himalayas--Hengduan Mountains is a centre for distribution of this section Cucubaloideae.
