山西陵川南方红豆杉群落种间联结与生态位特征研究

基于对山西陵川县境内野生南方红豆杉群落的样地调查,采用总体相关性VR检验、Pearson相关系数、Spearman秩相关系数和生态位测度方法,在群落尺度上对南方红豆杉群落的种间联结性和生态位特征进行了研究。结果显示:(1)南方红豆杉(Taxus chinensis(Pilger)Rehd.var.mairei(Lemee et Levl.)Cheng et L.K.Fu)、荆条(Vitex negundo L.var.heterophylla(Franch.)Rehd.)、鹅耳枥(Carpinus turczaninowii Hance)、连翘(Forsythia suspensa(Thunb.)Vahl)和三裂绣线菊(Spiraea trilobata L.)的重要值和生态位宽度较大,为群落中的建群种和优势种;(2)物种间生态位重叠指数总体偏高,种间竞争较强,尤其是南方红豆杉与其他物种之间;(3)群落总体呈显著负联结,大多数种对间呈中性关联(χ23.84,P0.05);(4)群落中物种间的Pearson相关系数、Spearman秩相关系数与生态位重叠指数之间表现为极显著的正相关(P0.01),而生态位宽度与生态位重叠指数之间未表现出线性关系,即物种间的竞争关系随种间关联性的增大而增强,而与生态位宽度没有直接关系。本研究可为保护和利用本区现有野生南方红豆杉资源提供合理的理论支撑。

A Revision of the Genus Ligusticum (Umbelliferae) in China

Ligusticum is a highly specialized genus in the tribe Ammineae Koch of the subfamily Apioideae. It is transitional between the tribe Ammineae Koch and the tribe Peucedaneae DC., and shows a very close affinity to the genus Selinum. In the present paper, the taxonomic history is reviewed; the external morphology, pollen morphology and geographic distribution are analysed, and its evolutionary tendencies are discussed. In addition, a key to the 34 species is provided, and economic uses reported in the literature are summarized. Ligusticum consists of over 60 species widely distributed in Eurasia and North America; the genus is typically temperate. There are two principal distribution centers, one in the Himalayas, including the Hengduan Mountains of western China, and the other in North America. Thirty-four species occur in China, most of which are distributed in the alpine belt of south-western China, with only a few species occurring in northern China. They usually grow in alpine thicket meadows or in alpine meadows. Among them are 28 species endemic to China, 4 of which are described as new in the present paper, i. e. L.yuayuanense, L.litanense, L.filifolium, and L.yunnanense. L.elatum (Edgew.) C. B. Clarke, a species of India, Afghanistan, and Pakistan, and L. thomsonii C.B.Clarke var. evolutior C. B. Clarke, of India, Pakistan and Kashmir, are reported from China for the first time. Some species are important in traditional Chinese medicine, for example, L. sinense Oliv., L. sinense Oliv. cv. Chuanxiong, L. sinense Oliv. cv. Fuxiong, L. delavayi Franch., L. jeholense (Nakai et Kitagawa) Nakai et Kitagawa, L. tachiroei (Franch. et Sav.) Hiroe et Constance, etc. The genus Tilingia was established by Regel in 1858, based on Tilingia ajanensis. The chief characters of the genus are distinct calyx teeth and carpels bearing a solitary vitta in each furrow. However, these characters do not differentiate Tilingia from Ligusticum, so that Tilingia was transferred to Ligusticum by Kozo-Poljansky in 1916. Tilingia tachiroei (Franch. et Sav.) Kitagawa was transferred to Ligusticum by Hiroe et Constance in 1958. Shan et Sheh in “F1. Reip. Pop. Sin.” Tom. 55 supported the treatment by Kozo-Poljansky and Hiroe and Constance The genus Ligusticopsis was separated from Ligusticum by Leute in 1969, based on the prominent calyx teeth of the former. Ligusticopsis included 14 species, all confined to China. But this genus has not been accepted by any other botanists since its establishment. The subdivision of Ligusticum in this paper is based mainly on the characters of involucel bracteoles and mericarps, combined with the shape and aperture types of pollen grains. The genus is divided into the following two sections. Sect.1 Ligusticum, Bracteoles linear or lanceolate, entire; mericarps slightly lateral-compressed to slightly dorsal-compressed; vittae solitary to numerous in each furrow; leaf-segments ovate, lanceolate, or linear; pollen grains mainly rhomboidal or ellipsoidal; apertures gonitreme. Sect. 2 Pinnatibracteola Pu. Bracteoles 1-3-pinnatisect or 2-3-lobed at apex; mericarps dorsal-compressed; vittae usually numerous in each furrow; leaf-segments usually linear, rarely ovate or lanceolate; pollen grains rectangular, elongate-rhomboidal, or equatorially constricted; apertures mainly peritreme, rarely gonitreme or intermediate.     

中国杏属一新种

描述了中国杏属一新种,华仁杏(Armeniaca cathayanaD.L.Fu,B.R.Li et J.H.Li,sp.nov.)。该新种与杏(Armeniaca vulgarisLam.)和山杏(A.sibirica(L.)Lam.)相似,但又有其独特特征,主要区别如下:叶两面疏被短柔毛,边缘具单锯齿和重锯齿,基部全缘;叶柄无腺体;单花或2~3朵花簇生;子房密被白色长柔毛;果核三角状卵球形,腹缝线具5~7条锐纵棱,背缝线具1条浅纵沟;种子大,两侧压扁,种仁质脆,无苦味。该新种由傅大立于2008年7月11日在河北省涿鹿县发现并采集,模式标本存于中国林业科学研究院(CAF),标本号:No.2008071101。     

从种子和叶片特征论高山三尖杉(Cephalotaxus alpina(Li)L.K.Fu)的分类地位(三尖杉科)

长期以来,对高山三尖杉（Cephalotaxus alpina(Li) L.K.Fu）分类地位的争议缺少可靠证据。本文从居群采样的水平上比较了高山三尖杉和三尖杉（Cephalotaxus fortunei Hooker）的叶片和种子形态特征,两者除种子的长宽比率无显著差异外,种子长度,宽度,厚度,长厚比率,宽厚比率以及叶片长度和宽度均差异极显著。此外,通过散点图分析表明两者的种子宽厚比和叶片宽度的变异是间断而稳定的,这一特征能将高山三尖杉和三尖杉明显地区分,结果支持将高山三尖杉作为种的等级较为合适,不赞成将高山三尖杉作为三尖杉的变种或亚种的分类处理。同时,对标本和原始文献的研究认为胡秀英(1964)发表的园桃杉（Cephalotaxus fortunei Hooker var. globosa S.Y.Hu）和高山三尖杉应是同一分类群。
