对国产(竹思)(竹劳)竹属(Schizostachyum Nees)进行了系统整理。对属的范围进行了修订,认为本属应包括乔草竹属(Dendrochloa Parkinson),薄竹属(Leptocanna Chia et H.L.Fung),长穗竹属(Teinostachyum Munro)和李海竹属(Neohouzeaua A.Camus),并首次建立了本属的属下分类系统。此外,对二种竹子起了新名:甲竹(Bambusa austro-sinensis Xia)和毛环单竹(B.yunnanensis Xia);作了4个新组合,即Schizostachyum coradatum(Wen et Dai)Xia, S.dumetorum(Hance)Munro var.xinwuense(Wen et J. Y Chin)Xia, Bambusa glaucescens glaucescens(Willd)Sieb. ex Munro var.annulata(W.T.Lin et Z.J.Feng)Xia和B.glaucescens (Willd)Sieb.ex Munro var.pubivagina(W.T.Lin et Z.J.Feng)Xia. 相似文献

(竹思)篣竹属及其近缘属叶表皮微形态特征 总被引:1,自引:0,他引:1
用扫描电镜和光学显微镜对(竹思)篣竹属(Schizostachyum Nees)7个种,及其近缘的梨竹属(Melocanna Trin.)、泡竹属(Pseudostachyum Munro)、薄竹属(Leptocanna Chia et H.L. Fung)各1个种以及空竹属(Cephalostachyum Munro)6个种的叶表皮微形态特征进行了观察.结果表明竹叶下表皮乳突的形状和在气孔器上及周围的排列式样在这5个属中各有不同,具有重要的分类学和系统学价值.同时我们的结果不支持广义的以属;而梨竹属、空竹属和泡竹属则被支持独立成属.另外,薄竹(Leptocanna chinensis)和红毛葸(竹思)篣竹(Schizostachyum sanguineum)的叶表皮微形态特征非常接近空竹属;香糯竹(Cephalostachyum pergracile)和金毛空竹(C.virgatum)的叶表皮微形态特征则十分接近(竹思)篣竹属. 相似文献

我国竹亚科空竹属(Cephalostachyum Munro)植物发现于云南和西藏两省区,集中分布于云南。根据形态学性状,以及近年来叶片微形态和分子系统学研究结果,作者对我国空竹属物种进行了整理并编制了分种检索表。结果显示,我国空竹属现知有7种,云南均有分布:薄竹(Cephalostachyum chinense(Rendle)D.Z.Li et H.Q.Yang)、空竹(C.fuchsianum Gamble et Hook.f.)、独龙江空竹(C.mannii(Gamble)Stapleton et D.Z.Li)、小空竹(C.pallidum Munro)、屏边空竹(C.pingbianense(Hsueh et Y.M.Yang ex Yi et al.)D.Z.Li et H.Q.Yang)、红毛空竹(C.sanguineum(W.P.Zhang)D.Z.LiH.Q.Yang)、真麻竹(C.scandens Bor)。薄竹属(Leptocanna Chia et H.L.Fung)和毒空竹(C.virulentum Y.M.Yang et F.Du)分别为空竹属和空竹的异名。另一方面,原置于空竹属的香糯竹(C.pergracile Munro)和金毛空竹(C.virgatum(Munro)Kurz)的形态特征则更接近狭义的竹属(Schizostachyum Nees),应该处理为狭义竹属成员。本研究对空竹属今后的修订工作有重要意义。 相似文献

竹叶中黄酮类化合物丰度的文献调研 总被引:1,自引:0,他引:1
《天然产物研究与开发》2015,(7)
(淡)竹叶具有很高的药用和食用价值,黄酮类化合物作为标志性的功能组分,其含量高低决定了竹叶的开发利用价值。本文综述了自1994~2013年间国内外公开发表的58篇文献,对涉及竹亚科18个属、91种竹叶的黄酮类化合物含量水平进行了分析研究。结果表明,干竹叶的总黄酮含量分布在4.60~25.43 mg/g之间,其中四种特征性碳苷黄酮(荭草苷、异荭草苷、异牡荆苷和牡荆苷)的总量为1.23~2.49 mg/g;倭竹属(Shibataea Makino ex Nakai)的总黄酮含量最高,思簩竹属(Schizostachyum Nees)最低;刚竹属(Phyllostachys Sieb.et Zucc.)叶片的总黄酮含量平均为16.34 mg/g,四种碳苷黄酮的含量合计为1.38 mg/g,其中异荭草苷含量最高(0.55 mg/g)。纵观整个研究现状,对刚竹属毛竹[P.heterocycla var.pubescens(Nazel)Ohwi]叶中黄酮类化合物的研究文献最多,涉及面最广。本研究结果以期为竹叶黄酮的开发利用提供一些帮助和指导。 相似文献

Species of Cephalostachyum Munro (Poaceae: Bambusoideae) from China are distributed in Yunnan and Tibet, mainly in Yunnan. In this paper, we discussed species of Cephalostachyum and compiled a key to species from China, based on recent studies on micromorphological characters of leaf epidermis and molecular phylogenetics of paleotropical woody bamboos. There is a total of seven species of Cephalostachyum distributed in China, all in Yunnan: Cchinense (Rendle) DZ. Li et HQ. Yang, Cfuchsianum Gamble et Hook. f., Cmannii (Gamble) Stapleton et DZ. Li, Cpallidum Munro, Cpingbianense (Hsueh et YM. Yang ex Yi et al.) DZ. Li et HQ. Yang, Csanguineum (WP. Zhang) DZ. Li et HQ. Yang and Cscandens Bor. Leptocanna Chia et HL. Fung and Cvirulentum YM Yang et F. Du are synonyms of Cephalostachyum Munro and Cfuchsianum Gamble et Hook. f. respectively. On the other hand, Cpergracile Munro and Cvirgatum (Munro) Kurz are morphologically closer to Schizostachyum Nees than to Cephalostachyum, and they should be treated as members of Schizostachyum. This paper is of significance to a worldwide revision of Cephalostachyum. 相似文献

The foliage leaf epidermis of 35 species representing 12 key genera of woody bamboos of the Asian tropics was investigated using light and scanning electron microscopy. The results indicated that papillae forms and distributional patterns around the stomatal apparatus of the abaxial foliage leaf epidermis were usually constant and were of great taxonomic significance at the specific and generic levels. However, papillae characters were not suitable for dividing subtribes within woody bamboos of the Asian tropics. On the basis of papillae characters, Schizostachyum s.s. and Cephalostachyum were confirmed, but their delimitations should be modified. The transfer of Leptocanna chinensis and Schizostachyum sanguineum into Cephalostachyum was supported, and Cephalostachyum virgatum and C . pergracile were confirmed to be members of Schizostachyum s.s. The subtribe Racemobambosinae did not obtain support and Racemobambos appeared to be better placed in subtribe Bambusinae. Neomicrocalamus was supported as a close relative and better treated as a synonym of Racemobambos . Gigantochloa was closely related to Dendrocalamus . © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 411–423. 相似文献

The fruit fly genus Ceratitis MacLeay (Diptera, Tephritidae) comprises several important pest species attacking a wide range of unrelated fruits. This is the third paper in a series revising the genus, and deals with representatives of the subgenus Ceratitis s.s . Eight species are recognized: Ceratitis brachychaeta Freidberg, C. caetrata Munro, C. capitata (Wiedemann), C. catoirii Guerin-Meneville, C. comuta (Bezzi), C. malgassa Munro, C. manjakatompo Hancock and C. pinax Munro. Lectotypes are designated for C. catoirii and C. pinax . A key for both sexes is provided, with illustrations of cephalic bristles, mesonotal and wing patterns, and shape of aculeus. All species are Afrotropical, except for 67. capitata , which has become widespread. The phylogeny and biogeography of Ceratitis s.s . are discussed, based on a cladistic analysis, and showing indications that the mediterranean fruit fly, C. capitata , may have its origins in eastern Africa. The relationship of this subgenus within the genus Ceratitis s.l . is also outlined. 相似文献

A new species of scorpion belonging to the family Pseudochactidae and the genus Vietbocap is described from the Tham Nam Lot cave, located in the Laotian part of the Khammouan-Ke Bang karst in Southeast Asia. Like the previously described species of the genus, Vietbocap lao sp. n. is a true troglobiont, but presents an even greater degree of adaptation to cave life, with a total lack of pigmentation and a very weak sclerotization of the tegument. This is the third troglobitic element known for the family Pseudochactidae. It represents the fifth known species of pseudochactid, four of which are from the Khammouan-Ke Bang karst system. Taking into account some marked differences between Vietbocap and the other two pseudochactid genera, a new subfamily, Vietbocapinae subfam. n., is proposed to accommodate this genus. 相似文献
