通过文献和标本考证，发现《中国植物志》第77卷第2分册和《Flora of China》第20~21卷中均误将黑穗橐吾(Ligularia melanothyrsa Hand.-Mazz.)鉴定为植夫橐吾(L. fangiana Hand.-Mazz.)，而真正的植夫橐吾应处理为川鄂橐吾[L. wilsoniana (Hemsl.) Greenm.]的异名。

Through literature and herbarium surveys, it was found that Ligularia melanothyrsa Hand.-Mazz. had been misidentiifed as L. fangiana Hand.-Mazz. in the Flora Reipublicae Popularis Sinicae 77(2) and in the Flora of China 20-21, and that L. fangiana should be placed in synonymy under L. wilsoniana (Hemsl.) Greenm.

将康定橐吾(Ligularia kangtingensis S.W.Liu)处理为细茎橐吾[L.hookeri(C.B.Clarke)Hand.-Mazz.]的异名。Senecio ficariifolius H.Lév.Vaniot长期以来被处理为细茎橐吾的异名,但我们检查模式材料后发现其头状花序盘状,与头状花序辐射状的细茎橐吾明显不同,而与头状花序盘状的贵州橐吾[L.leveillei(Vaniot)Hand.-Mazz.]没有区别,故将其处理为贵州橐吾的异名。

Ligularia kangtingensis S. W. Liu is reduced herein to the synonymy under L. hookeri (C. B. Clarke) Hand.-Mazz. The name Senecio ficariifolius H. Lév.&Vaniot has long been placed in synonymy under L. hookeri, a species with radiate capitula. Examination of the type specimens of S. ficariifolius has shown that it has discoid capitula, and thus is readily distinguishable from L. hookeri, but not essentially different from L. leveillei. We therefore place S. ficariifolius in synonymy under L. leveillei.

摘要：通过查阅标本和野外观察,发现根据采自云南西北部丽江玉龙山标本描述的玉龙山翠雀花（DelphiniumyulungshanicumW.T.Wang）和硕片翠雀花（D.grandilimbumW.T.Wang＆M.J.Warnock）实际上属于目前仅知在该山体有分布的鞘柄翠雀花（D.coleopodumHand.-Mazz.）的较小个体,故将它们处理为鞘柄翠雀花的异名.

Both herbarium and ifeld observations have shown that Delphinium yulungshanicum W. T. Wang and D. grandilimbum W. T. Wang&M. J. Warnock, both described from Yulong Shan, Lijiang, northwestern Yunnan, China, are no more than a diminutive form of D. coleopodum Hand.-Mazz., a species currently known only from Yulong Shan. We therefore reduce them to the synonymy of D. coleopodum.

为筛选适合恩施州高山地区生长、适应市场的茭白[Zizania caduciflora(Turcz.)Hand.-Mazz.]优良品种,试验以浙茭2号为对照,对鄂茭2号(6、8号株系)、"208"、"005"、蒋墅、秋玉和鄂茭1号7个茭白材料进行了引种及适生性试验。结果表明,不同茭白材料物候期各异。鄂茭2号6号株系和8号株系成熟最早,鄂茭1号最晚熟。鄂茭2号6号株系和"005"产量最高,综合性状最好的是鄂茭2号6号株系,良好的有"005"和秋玉,这3个材料适合在恩施州高山地区大面积发展。

Seven different cane shoots varieties were selected to screen suitable cane shoots variety in the alpine areas of En-shi prefecture. Results showed that different variety had different phenophase. No. 6 and No.8 strain of Ejiao No.2 had the earliest maturity stage. The maturity stage of Ejiao No.1 was the latest. The yield of No.6 strain and “005” were the highest, increased by 2.7% compared with the average yield. The quality of “005”, Qiuyu and Ejiao No.1 were the best and Jiangshu was the worst. The comprehensive characters of No.6 strain of Ejiao No.2 was the best, followed by “005” and Qiuyu, suit-able for planting in the alpine areas of Enshi prefecture.

对皖南亚热带常绿阔叶林林下灌木层主要树种草珊瑚〔Sarcandra glabra(Thunb.)Nakai〕、乌药〔Lindera aggregata(Sims)Kosterm.〕、香桂(Cinnamomum subavenium Miq.)、红楠(Machilus thunbergii Sieb.et Zucc.)、连蕊茶〔Camellia cuspidata(Kochs)H.J.Veitch〕、甜槠〔Castanopsis eyrei(Champ.ex Benth.)Tutch.〕、矩叶鼠刺(Itea oblonga Hand.-Mazz.)、红淡比(Cleyera japonica Thunb.)和小叶蚊母树〔Distylium buxifolium(Hance)Merr.〕叶片养分(包括C、N、P、K、Ca和Mg)含量、单位叶面积养分含量和比叶面积进行了测定,并分析了比叶面积与养分含量和单位叶面积养分含量的相关性。结果表明:9种树种叶片的C、N、P、K、Ca和Mg含量分别为438.09~492.31、9.79~15.60、0.33~2.06、11.39~32.52、3.84~13.34和2.85~14.05 g·kg-1,单位叶面积C、N、P、K、Ca和Mg含量分别为24.48~47.38、0.66~1.03、0.02~0.21、0.73~1.82、0.22~1.35和0.20~1.05 g·m-2,C/N比、C/P比和N/P比分别为31.40~47.88、227.76~1 495.66和5.26~32.90。9种树种叶片的比叶面积平均值为14.5 m2·kg-1,其中草珊瑚的比叶面积最大(17.90 m2·kg-1)、小叶蚊母树的比叶面积最小(9.89 m2·kg-1)。相关性分析结果表明:供试树种叶片的C/P比与N/P比间呈极显著正相关;比叶面积与叶片N含量呈显著正相关,与单位叶面积C、N和Ca含量分别呈极显著和显著负相关,与其他指标的相关性均不显著。综合分析结果表明:皖南亚热带常绿阔叶林下灌木层主要树种叶片的养分含量及比叶面积差异明显,其中,乌药、草珊瑚、矩叶鼠刺和香桂叶片的养分含量较高,而小叶蚊母树、红淡比和红楠的单位叶面积养分含量较高。

Nutrient ( including C, N, P, K, Ca and Mg) content in leaf, nutrient content per unit leaf area and specific leaf area ( SLA ) of main tree species Sarcandra glabra ( Thunb.) Nakai, Lindera aggregata ( Sims ) Kosterm., Cinnamomum subavenium Miq., Machilus thunbergii Sieb. et Zucc., Camellia cuspidata ( Kochs) H. J. Veitch, Castanopsis eyrei ( Champ. ex Benth.) Tutch., Itea oblonga Hand.-Mazz., Cleyera japonica Thunb. and Distylium buxifolium ( Hance) Merr. in shrub layer under subtropical evergreen broad-leaved forest in Southern Anhui were determined, and correlations of SLA with nutrient content and nutrient content per unit leaf area were analyzed. The results show that contents of C, N, P, K, Ca and Mg in leaf of nine tree species are 438. 09-492. 31, 9. 79-15. 60, 0. 33-2. 06, 11. 39-32. 52, 3. 84-13. 34 and 2. 85-14. 05 g·kg-1 , respectively; contents of C, N, P, K, Ca and Mg per unit leaf area are 24 . 48-47 . 38 , 0 . 66-1 . 03 , 0 . 02-0 . 21 , 0 . 73-1 . 82 , 0 .
