中国山矾科的初步研究(续)

This paper is a preliminary study on the morphology, taxonomy and geog- raphy of Symplocaceae, following the system of H. P. Nooteboom and H. Handel-Maz- zetti et E. Peter-Stibal, who divided the genus into two subgenera according to the floral characteristics.  But I disagree with Nooteboom's unduly broad specific concept, and adopt Handel-Mazzetti et Peter-Stibal's concept, which usually treated the species of this family according to their habitats in regions in a relatively narrow sense.  The ge- nus is divided in the present paper into two subgenera, six sections, among which two are new.  Nine new species and three new varieties are described in this paper.  Discus- sions on some taxa are also presented.      The family Symplocaceae consists of 300 species in the whole world.  They are dis- tributed mainly in tropical and subtropical Asia, Oceania and America.  In China there are about 77 species widely distributed in the  south-western and south-eastern parts, with only one species, namely Symplocos paniculata (Thunb.) Miq. extending northward to north-eastern part.

中国防己科药用植物的初步调查

 The Menispermaceae is a well-known alkaloid-rich family within the flowering plants.  Because of the therapeutic value and pharmacological actions of the alkaloids, contents of its members it has, besides taxonomists also attracted the attention of chemists, pharmacists and other research workers.  In the present work, the menisper- maceous medicinal plants of this country are dealt with from their taxonomical, phy- tochemical and therapeutic aspects.      As a result of our preliminary study, out of 18 genera with some 70 species so far found in China, 15 genera with 51 species and 2 varieties are known to possess medicinal value, of which some are famous Chinese drugs, viz. Stephania tetrandra S. Moore (粉防己), Tinospora callipes Gagnep. (金果榄), Sinomenium acutum (Thunb.) Rehd. et Wils. (青藤); some are important folk remedies, e.g. Archangelisia loureirii (Pierre) Diels (古山龙), Stephania cepharantha Hayata (金线吊乌龟); and some are raw materials for the preparation of medicines,  e.g. Fibraurea tinctoria Lour. for tetrahydropalmatine, Stephania sinica Diels for rotundine, etc.       After a careful taxonomic examination, two new species,  Cocculus mokaingensis Lien, Pericampelos omeiensis Lien, are found and herewith discribed.       Isoquinoline alkaloids are widely distributed in the whole family.  The Trib. Aniamirteae consisting of genus Arcangelisia,  the  Trib.  Fibraureae  consisting  of genera Tinomiscium and Fibraurea, as well as the  Trib.  Tinosporeae consisting of genera Tinospora and Parabaena are charaterized by the presence of proberberine alkaloids,  e.g.  berberine,  palmatine,  jatrorrhizine,  columbamine,  etc.  and  such alkaloid-bearing plants are commonly used as antiperiodic, antidote, antibiotic, anti- malarial,  etc.  On  the  other  hand,  the  Trib.  Menispermeae  elaborates  mainly bisbenzylisoquinoline-type alkaloids, and these plants are usually used in the treatment of rheumatism, and often as an anodyne, diuretic etc.      To facilitate identification, 10 plates are here provided.     

中国水锦树属的初步研究(续)

This paper presenta a brief introduction to the taxonomy and geographic distribu- tion of the genus Wendlandia.       The genus Wendlandia in tribe Rondeletieae of the family Rubiaceae was proposed by Bartling in 1830. There are now more than ninety species throughout the world. It is distributed mainly in tropical and subtropical Asia. Thirty species, ten subspecies and three varieties are recorded in the paper. Among these, nine species, two subspecies and one variety are new. They are distributed mainly in Yunnan, Guizhou, Guangxi, Guangdong, Xizang and Taiwan Provinces. Only one species, namely W. longidens (Hance) Hutch. Extends northward to Hubei and Sichuan.       The classification of the genus in this paper is based on Cowan's system. It is divided into four series mainly by their stigmatic and staminal characters, namely Euexsertae, Subinclusae, Montigenae and Clavigerae. The first two series are each subdivided according to the stipule feature into two subseries, designated as Cuspidatae, Orbiculares, Tinctoriae and Paniculatae.       From the distribution patterns of the genus in the flora of China, we may understand:       1.  The genus has the most species in China, where is its distribution centre, and Yurnan is the province richest in species of the genus.       2.  There are twenty-one species, five subspecies and three varieties endemic to China. Most of these endemics have their distributional area confined to a single province, and some of them are confined to an even narrower district, with only a few of them extending beyond province boundaries.       3.  The series Subinclusae Cowan has the most species not only in China but also in other regions of the world, whereas the series Montigenae Cowan has fewer species and they are all restricted to China.       The new species, new subspecies and the new varieties described in this paper are as follows: W. brevipaniculata W. C. Chen, W..villosa W. C. Chen, W. tinctoria  (Roxb.) DC. subsp. affinis How, W. laxa S. K. Wu, W. uvariifolia Hance subsp. pilosa W. C. Chen, W. guangdongensis W. C. Chen, W. parviflora W. C. Chen, W. scabra Kurz var. pilitera How, W. pubigera W. C. Chen, W. jingdongensis W. C. Chen, W. brevituba Chun et Howand W. oligantha W. C. Chen.     

中国水玉簪属Burmannia L.区系特征的初步研究

The genus Burmannaia is one of the largest genera in the Burmanniaceae, of which 12 species have been recorded in China.  It is mainly a tropical genus.  The species in China are all confined to the region south of Yangtze River. They are distributed chiefly in the provinces Guangdong (9 species) and Yunnan (6 species). After having studied the areas of all the species in China, we are able to classify them into follow- ing 4 area-types:      1.  Area-type of Tropical Asia to Tropical Australia. The two non-saprophytic species (Burmannia disticha, B. caelestis) and one saprophytic (B. championii) belong to this area-type.  It is an ancient type.  The plants of this type mostly have a wide ecological amplitude, for example, B. disticha may be found in tropical and subtropical regions.  The plants occur not only in evergreen forests, in bushs, but also in rather arid herbosa and on the side of streams (Fig. 2).     2. Area-type of Tropical SE Asia.  In the type are 3 saprophytic species i.e. B. oblonga, B. wallichii and B. nepalensis.      3. Area-type of E. Asia.  (Fig. 3) Burmannia in China with E. Asian distribu- tion is poor in species.  There are only 2 saprophytic species. B. cryptopetala is distri-buted in Haina (China), Kyushu and Honshu (Japan); B. itoana occurs in Taiwan (China), Riukiu and Kyushu (Japan).  They are known only on the islands of E. Asia. Such a pattern of distribution may suggest connection of these islands once in the prehistoric time in spite of their present isolation.      4.  Endemic area-type. (Fig. 4).  Here are 3 saprophytic species and one variety with green leaves.  B. nana occurs only in E. Taiwan.  One of the two new species described by present author in this paper, B. fadouensis, is known from Xichou Xiao, S. E. Yunnan, to Longzhou Xian of the province Gaunxi; the other one, B. pingbien- ensis occurs only in Pinbien Xian of S. E. Yunnan. The last species is endemic to China. B. pusilla var. hongkongensis is non-saprophytic and known from the province Guang- dong and its bordering islands.  Both B. fadouensis and B. pingbienensis are characte- rized by the axillary bulbils, which enable them to adapt to rather arid and cold condi-tions in northern part of the tropical region.     

浅析资产质量

资产的数量可以反映一个企业的生产经营规模。但是 ,等量的资产往往不能带来等量利润。这是因为资产不仅有量的规定性 ,还有质的规定性。因此 ,必须重视资产质量的管理。在实践中 ,从固定资产按使用情况分为在用、不需用、未使用等几类 ,到对存货提取“商品削价准备”“存货跌价准备”再到资产重组中的“剥离不良资产 ,注入优质资产”都是资产质量管理的具体手段。因此 ,本文拟对资产质量的几个理论与实务问题进行初步探讨。一、资产质量的概念资产质量是企业资产盈利性、流动性和安全性的综合水平。资产的盈利性是指资产获取未来经济利益的…     

中国梅花衣属的初步研究

 Parmelia is a genus of economical importance.   According  what  was  recorded, Meyen & Flotow were the first foreigners to study Chinese lichens in 1843.  Up to the present time 74 species, 24 varieties and 11 forms have been described from China.      The majority of specimens reported in this paper were collected by many Chinese botanists and collectors from 21 provinces from 1928--1962, while a few of them were collected by Licent from 1916 to 1917 and by Poliansky in 1957.      The system of classification adopted here is that held by A. Zahlbruckner in 1926. But in section Hypotrachyna, the two subsections-Myelochroa and Myeloleuca proposed by Asahina are adopted and Parmelia xanthocarpa which has not been properly placed before, is here referred to the subsection Myelochroa.      In the subgenus Hypogymnia the writer discovers that the length of spores of two species are longer than 10μ, especially  Parmelia macrospora reaches  17.5μ long.  So far as the writer knows, the upper limitation of the spore length  recognized  by  many lichenologists has been 10μ in this subgenus.  The spore measurement of this subgenus needs, therefore, to be revised in future.       In this paper 78 species, 14 varieties and 6 forms are presented.  Among them, 5 species, 5 varieties and 1 forms are considered as new and two new combinations have been made.  Out of all these, 31 species, 6 varieties and 2 forms are first recorded from China.  All the materials cited are deposited in the Mycological Herbarium of Instituteof Microbiology, Academia Sinica, Peking.

中国凤尾蕨属细胞学的初步研究

本文报道了中国产10种凤尾蕨属植物和2种蕨属和栗蕨属植物的细胞学研究结果。  在凤尾蕨   属中，8种是多倍体或具有多倍体细胞型，4种是无性孢子繁殖的后代，6种实际上是种复合体或种复合   体成员，单纯有性生殖的二倍体只有2种。凤尾蕨至少具有9条孢子发生路线，在其同一个体上除了产   生二倍孢子外，还可能产生少量加倍或多倍孢子；广义的蜈蚣草实际上是个种复合体，其祖先的二倍体   细胞型广泛分布于中国亚热带地区说明这里可能是该复合体的起源中心；岩凤尾蕨具有不寻常的染色  体数目n＝55，这说明在本属和本科中可能存在着非整倍体进化。
