本文阐述樟科木姜子属及山胡椒属两者在形态、分布、起源及演化等方面有许多共同之处,不仅在属内具有平行演化的情况,而且各自平行演化成单花木姜子属 Dodecade-nia和单花山胡椒属Iteadaphne。同时两者又分别自4药室的拟擦术属Parasassafras和2药室的黄脉擦术属 sinosassafras演化而来。本文将单花木姜子亚属 Litsea subg.Uniflos Yang et P.H.Huang归人单花木姜子属,并把 Litsea monantha Yang et P.H.Hu-ang一种作为单花木姜子(原变种)Dodecadenia grandiflora Nees var.grandiflora的新异名,恢复了单花山胡椒属Iteadaphne Bl.,并将香面叶Lindera caudata(Nees)Hook·f.重新组合归入该属为Ⅰ.caudata(Nees)H.W.Li,comb.nov。此外,本文还发表了一个新属即黄脉擦木屑 Sinosassafras H.W.Li,gen.nov.,它具有2药室花药而不同于其平行演化的拟擦本属。  相似文献

本文为作者在研究樟科月桂族的基础上,通过对一些有关问题的讨论,阐明月桂族在樟科中的地位。假伞形花序下的苞片由螺旋状排列(互生)演变成外面的苞片增大、质地变厚变硬,并两两交互对生,可视为假伞形花序演进的重要阶段,构成了月桂族关键性的形态特征.月桂族在命名上过去延用木姜子族Tribus Litseeae Mez,因在这一族内包括有樟科Lauraceae的模式属月桂圆Laurus L.,根据现行的《国际植物命名法规》应该用月桂族Tribus Laureae的名称。  相似文献

This paper is an attempt to discuss the relationship and phylogeny within the genus Lindera, based upon on analysis of shortened brachlets, on which the inflorescences are inserted, and other morphological characters. The shortened branchlets are metamorphic shoots which are often at the transitional stage between branchles and inflorescences. The advanced shortened branchlets usually with an undeveloped terminal bud, posses scale-like leaves, and the inflorescences so formed are sessile and aggregate. In primitive taxa, such as Lindera nacusua (Don) Merr., L. gracilipes H. W. Li and L. tanchuanensis Feng et H. S. Kung, the branchlet is usually not shortened, with well-developed terminal bud, forming a single axillary pseudo-umbel, while its peducle is usually very slender and stamens of pistillate flower sometimes more or less developed. The leaves on the upper part of branchlet are normal and the lower part of branchlet becoming bracteal, In the genus the development of shortened branchlets (Fig. 1.) from the ones in the primitive taxa to the ones in the advanced taxa may be found. Other important morphological characters are the length of peducles. The peduncle is usually slender in the primitive taxa, short or even sessile in the adanced taxa. There are two types of venation in the genus: the pinnate and trinerved. As the primitive group trib. Perseeae Mez shows pinnate veins, pinnate ventation in Lindera is more primitive than trinerved one. It might be possible that a transition occure in the genus from evergereen habit to deciduous one as shown in Lindera glauca B1., L. angustifolia Cheng and L. praecox B1., whose leaves tardily wither but persistent over winter. The relationships within Lindera are shown in a hypothetical genealogical tree (Fig. 4), which includes the system of Litsea, developed parallelly with Lindera. From the study of morphological characters, the author infers that both Lindera and Litsea have originated from a common ancestory related to the tribe Cinnamomeae Baill. which has a single axillary inflorescence, with hermaphrodite flowers, 4-locular anthers and penninerved to trinerved leaves.  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: Cchinense (Rendle) DZ. Li et HQ. Yang, Cfuchsianum Gamble et Hook. f., Cmannii (Gamble) Stapleton et DZ. Li, Cpallidum Munro, Cpingbianense (Hsueh et YM. Yang ex Yi et al.) DZ. Li et HQ. Yang, Csanguineum (WP. Zhang) DZ. Li et HQ. Yang and Cscandens Bor. Leptocanna Chia et HL. Fung and Cvirulentum YM Yang et F. Du are synonyms of Cephalostachyum Munro and Cfuchsianum Gamble et Hook. f. respectively. On the other hand, Cpergracile Munro and Cvirgatum (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 seed oils of three species (Litsea cubeba (Lour.) Pers, L. auriculata Chien et Cheng, L. subcoriacea Yang et P. H. Huang) were examined and the fatty acid composition of these oils was determined by GLC. Their major fatty acid was identified as lauric acid, Its amount ranged from 34.6%–75.4%. The major acid of the fruit coat oil from L. subcoriacea Y. H. Huang was different from that of the seed oil. The former contained 50% linoleic acid. The unsaturated C10, C12, C14 acids of the seed oil from L. cubeba (Lour.) Pers were separated by distillation, column chromatography and were identified by Periodate-Perman-ganate oxidation, IR, NMR and MS. They are cis-4-decenoic, cis-4-dodecenoic and cis-4-tetradecenoic acids respectively.  相似文献
