The somatic chromosome number and detailed chromosome morphology have been studied in ten species of Anemone, one species of Anemoclema, and six species of Clematis, all from China, namely Anemone davidii Franch. (2n=4x= 32), A. stolonifera Maxim. (2n=2x=16), A. flaccida Fr. Schmidt (2n=2x= 14), A. rivularis Buch.-Ham. (2n=2x= 16), A. begoniifiolia lévl. et Vant. (2n=2x= 16), A. hupehensis Lem. f. alba W. T. Wang (2n =2x = 16), A. tomentosa (Maxim.) Péi (2n=2x= 16), A. rupestris Hook. f. et Thoms. (2n=2x= 14), A. trullifolia var. colestina (Franch.) Finet et Gagnep. (2n = 2x = 14), A. trullifolia var. holophylla Diels (2n=2x= 14), A. demissa Hook. f. et Thoms. (2n=2x= 14), Anemoclema glaucifolium (Franch.) W. T. Wang (2n= 2x= 16), Clematis kockiana Schneid. (2n= 2x=16), C. rehderiana Craib. (2n = 2x = 16), C. ranunculoides Franch. (2n = 2x = 16), C. puberula var. ganpiniana(Lévl. et Vant. ) W. T. Wang (2n = 2x = 16), C. brevicaudata DC.

The species of x = 8 in Anemone, and those in Anemoclema and Clematis have very similar karyotypes which consist of five pairs of large median-centromeric (rarely one pair of which are submedian-centromeric) and three pairs of subterminalor terminal-centromeric chromosomes.

中国姜黄属植物的订正

将白顶姜黄（CurcumaalbicomaS．Q．Tong）归入川郁金（C．sichuanenslsX．X．Chen),将另一种“川郁金”（C．chuanyujinC．K．HsiehetH．Zhang）归入广西莪术（C．kwangsiensisS．G．LeeetC．F．Liang）。认为过去把莪术鉴定为C．zedoaria（Christ．）Rose．C．caesiaRoxb．或C．aeruginosaRoxb,其实都是C．phaeocaulisVal．的误定;C．elataRoxb．是C．wenyujinY．H．ChenetC．Ling的误定;认为广西莪术的两个变种,即紫脉莪术（C．kwangsiensisvar．affinisY．H．Chen）和毛莪术（C．kwangsiensisvar．puberulaY．H．Chen）不能成立．对台湾是否产C．viridifloraRoxb．表示怀疑。附有中国产姜黄属植物12种的检索表及其分布．     

双蝴蝶属和蔓龙胆属（龙胆科）种子表面特征的研究

在扫描电镜下观察了龙胆科双蝴蝶属8个种和蔓龙胆属6个种的种子表面纹饰,观察结果表明,2属的种子表面特征均为网状纹饰类型。其中Tripterospermun cordatum,T.volubile,T.chinense,T.discoideum,T.japonicum,T.filicaule,Crawfurdia delavayi和C.pri-cei的种子表面为细网状;T.hirticalyx,T.pingbianense,C.puberula,C.tibetica,C.campanu-lacea和C.crawfordioides的种子表面为粗网状,在龙胆属Gentiana的不同组中均存在网状纹饰,因此,从种子表面特征可看出,龙胆属,双蝴蝶属和蔓龙胆属3属间具较近的亲缘关系。同时,在双蝴蝶属中,种之间在种子表面特征上有分化。在表面纹饰的具体特征上存在较大差别,而在蔓龙胆属中种间差别很小,仅在一些种子表面有无附属物上存在差异。     

Does cladode inclination restrict microhabitat distribution for Opuntia puberula (Cactaceae)?

In contrast with other Opuntia species, most of the cladodes of Opuntia puberula have a horizontal position. This study explores whether the horizontal cladodes are an adaptive trait to increase light interception in the understory or are a neutral trait, and if this characteristic may prevent its distribution in full sun habitats. Cladode inclination angle and its effect on light interception, cladode temperature, and carbon gain are characterized, and anatomical and physiological traits of upper and lower cladode surfaces are described. Inclination angle was under 50° for 95% of the cladodes, and the frequency of low inclination angles increases as light availability decreases. Nocturnal acid accumulation increased with total daily PPFD intercepted, but no significant differences were detected between typical horizontal cladodes and the few vertical cladodes. Chlorophyll content differed in the upper and lower surfaces of horizontal cladodes; however, chlorenchyma thickness, stomatal conductance, and nocturnal acid accumulation were similar between surfaces. The horizontal position of O. puberula cladodes, which is anatomically determined, restricts it to shaded habitats, where the plants do not overheat, but seems to have no effect on carbon gain.     

Responses of common and successional heathland species to manipulated salt spray and water availability

Coastal sandplain heathlands are a rare plant community in the northeastern United States. Salt spray and water availability are likely important factors determining heathland distribution. Field surveys and manipulative experiments were performed to examine heathland species' responses to salt spray and water availability. We surveyed field distributions of four typical heathland species: Solidago puberula, Solidago rugosa, Gaylussacia baccata, and Myrica pensylvanica. The distributions of two native tree species, Pinus rigida and Quercus ilicifolia, were also surveyed because they succeed into coastal heathlands with low disturbance frequency. We then manipulated salt spray and water in the field and measured species' water status, necrosis, and growth responses to the treatments. Predawn xylem pressure potential and necrosis were strongly affected by high salt spray and low water availability. Shoot elongation was also limited in S. puberula and S. rugosa grown in high salt, low water treatments. Gaylussacia baccata and Q. ilicifolia were particularly sensitive to high salt spray and low water, suggesting that they might excluded be from areas with those conditions. The interaction between salt spray and water availability could affect the landscape scale and should be incorporated into conservation management plans.
