牛紏吴茱萸柄锈菌新种

本文描述了采自海南省琼中县牛紏吴茱萸Evodia trichotoma (Lour.) Pierre(芸香科)上的柄锈菌一新种——Puccinia evodiae-trichotomae J. -y. Zhuang。本种与巴布亚一新几内亚产的吴茱萸Evodia sp.上的另一种柄锈菌Puccinia evodiae Cumm.略近似,但冬孢子堆裸露呈垫状,而后者则深埋于病瘿中。冬孢子形状与大小和后者相仿,然而少数孢子可长达60μm,顶壁有时略增厚,颜色很浅或近几色。镜下可见一些孢子已萌发,推测可能属无眠冬孢型。芸香科植物上的柄锈菌目前仅知10种,本种特征与它们均不相同,故鉴定为新种。本新种模式标本保藏在中国科学院微生物研究所真菌标本室。     

中国蓼科植物柄锈菌的分类研究

蓼科植物((Polygonaceae)具有重要的经济意义.其中有粮食作物,著名中药,蜜源植物,观赏植物以及其它经济植物.柄锈菌(Puccinia)是蓼科植物的重要的病原真菌.本文对我国寄生于蓼科植物的柄锈菌进行了分类研究. 在中国首先报告蓼科植物柄锈的是日本人三宅市郎(1914).我国真菌学家从30年代起分别描述或记载过各种蓼科植物的柄锈,并发表过一些中国特有的新种. 本文作者重新研究了中国科学院微生物研究所真菌标本室收藏的全部蓼科植物柄锈的标本以及近年来采集的未定名标本.共鉴定标本262号,得柄锈30种,包括5个新种:汶川柄锈(Pucinia wencuanensis),雾灵柄锈(P. wulingensis),南迩巴瓦柄锈(P.namjagbarwana),太白柄锈(P. taibaiana),掌叶大黄柄锈(P. rhei palmati),和五个国内新记录种:装饰柄锈(P, ornata),岩手山柄锈(P. iwateyamensis),山蓼柄锈(P. oxyriae),赫尔顿柄锈(P.hultenii),箭叶蓼柄锈(P.polygoni-sieboldii).寄主植物包括蓼科8属47种.

Corydalis hirtipes B.U. Oh et J.G. Kim: A new species ofCorydalis sectCorydalis (Fumariaceae) from Korea

Here we describe a new species ofCorydalis sectCorydalis (Fumariaceae), namely C.hirtipes B.U. Oh et J.G. Kim. This species, from the central part of Korea, is clearly distinguished from other species of sectCorydalis by its simple, unicellular hairs that are densely distributed on the stems, peduncles, and petioles. It is also distinctive from its close relative C.albipetala in having ternate leaves, lobate or parted leaflets, dentate or cleft bracts, and broad, fusiform fruits.     

Vier neue Arten der GattungJacaranda (Bignoniaceae) aus dem Südosten Brasiliens

Four new species ofJacaranda have been found in the coastal mountain-ranges of SE-Brazil where they occupy characteristic ecological positions.J. montana andJ. subalpina are related toJ. puberula agg.,J. pulcherrima shows affinities toJ. ulei but also toJ. subalpina. J. crassifolia is very distinct and possibly related toJ. obovata.

广西石灰岩地区苦苣苔科植物一新种——北流报春苣苔

报道了广西石灰岩地区苦苣苔科报春苣苔属(Primulina Hance)1新种——北流报春苣苔(P. beiliuensis B. Pan & S. X. Huang)。该新种在形态上与黄花牛耳朵[P. lutea(Yan Liu & Y. G. Wei)Mich. Möller & A. Weber]较近,但叶宽卵形,叶基部近心形,叶缘具浅钝齿或呈浅波状齿,花冠紫色,花冠、花序梗、花梗、苞片及花萼均被紫色短柔毛而区别与后者; 分子生物学证据表明,在系统发育上与桂林小花苣苔[P. repanda var. guilinensis(W. T. Wang)Mich. Möller & A. Weber]近缘,但两者在形态学上相差较远。     

Studies in Brazilian Passifloraceae III. A new species of Passiflora

A new species ofPassiflora from Minas Gerais, Brazil, is described and namedP. saccoi. This species belongs to subgenusPassiflora seriesLobatae harms because of its lobed leaves, foliaceous, semi-ovate to semi-oblong stipules that are attached on one side above base and, hence, often appear sub-reniform, and foliaceous, verticillate bracts borne near the apex of the peduncle.     

A new loach, Cobitis shikokuensis (Teleostei: Cobitidae), from Shikoku Island, Japan

A new species of spinous loach, Cobitis shikokuensis, is described based on 297 specimens from Shikoku Island, Japan. The new species was formerly known as the Shikoku group of Cobitis takatsuensis. It can be distinguished from other species of Cobitis and closely related genera by a combination of the following characters: dorsal fin with 6 branched soft rays; anal fin with 5 branched soft rays; one brownish streak across eye from the tip of nose, no streak on cheek; a black spot smaller than eye diameter near the dorsal corner of the caudal fin base; 3–5 small brownish speckles on ventral side of caudal peduncle; high caudal peduncle with well-developed fleshy keels on dorsal and ventral side; a lamina circularis at base of dorsal part of pectoral fin absent; first branched soft ray of pectoral fin broad in males; pectoral soft rays widely branched from the approximate midpoint; last anal fin ray with 2 elements; interorbital width 11.2–17.1% of head length.     

Saprolegnia salmonis sp. nov. isolated from sockeye salmon,Onchrhynchus nerka

A saprolegniasis occurred in cultured sockeye salmon,Onchorhynchus nerka, raised in Hokkaido, Japan. The lesions were mainly observed in the head, peduncle region and the caudal fin. All strains isolated were morphologically classified in the genusSaprolegnia. They were identified as a new species in the genus from the characteristics of the sexual organs, and namedSaprolegnia salmonis.     

A taxonomic review ofXenotilapia sima andX. boulengeri (Cichlidae; Perciformes) from Lake Tanganyika

Two cichlid fishes from Lake Tanganyika,Xenotilapia sima Boulenger, 1899 andX. boulengeri (Poll, 1942) are often confused owing to insufficient information on the diagnostic morphological characters for each species. Morphological and morphometric analyses showed thatX. sima differs fromX. boulengeri in having a greater number of teeth and anal and pectoral fin soft rays, thicker caudal peduncle, larger eyes, and a shorter snout and anal fin base.
