云南凤仙花属一新种及一新记录种

报道了在云南西南部发现的凤仙花属一新种——滇红凤仙花（Impatiens quintadecimacopii G.W.Hu&Q.F.Wang）和一新记录种——伸展凤仙花（I.porrecta Wall.ex Hook.f.&Thomson）。这两个种在形态上很相似,但在花色、侧萼片形状、旗瓣形状和蒴果颜色上明显有别。根据形态特征,这两个种应属于凤仙花亚属（I. subg.Impatiens）单花组（I. sect.Uniflora）。结合核糖体DNA内转录间隔区序列（ITS）与叶绿体atpB-rbcL间隔区序列开展系统发育分析,结果进一步确认了这两个种关系紧密,以及它们在单花组内的系统位置。

Chamaelirium shimentaiense (Melanthiaceae), a new species from Guangdong,China

Chamaelirium shimentaiense (Melanthiaceae), a new species from Shimentai Nature Reserve, Guangdong Province, China is described. This species is similar to C. shiwandashanense and C. viridiflorum in having actinomorphic flowers with six tepals and unilocular anthers, but is easily distinguished from them by its strongly undulate leaf blades with crispulate margins and inconspicuous venation, purplish tepals with a slightly broadened and obtuse apex, and purple-tinged filaments. The infrageneric assignment of this species is discussed and a color plate is provided.     

Comparative morphology of the carpel in the Liliaceae: Helonieae

Most Helonieae have only slight septal indentations between the three carpels: in Xerophyllum deep septal clefts extend centripetally and completely enclosed, narrow septal pockets occur in Metanarthecium . Other unique generic features are found: tepallary-staminal nectarial glands in Heloniopsis , zygomorphy in Chionographis , and dioecism in Chamaelirium . The carpels are biovulate in Chionographis; there are two to several ovules per carpel in Xerophyllum; 8–12 ovules occur in the carpel of Chamaelirium; and numerous bitegmic ovules are borne in many longitudinal rows on enlarged placentae in Helonias, Heloniopsis, Metanarthecium , and Ypsilandra . Except for Metanarthecium , this last-named group of genera displays a near ring composed of 'accessory' placental bundles and a compound septal bundle (with normally oriented xylem and phloem) in cross-section at the inner edge of each septum. Ventral bundles occur in the other four genera.     

Parentage analysis in Chamaelirium luteum (L.) Gray (Liliaceae): why do some males have higher reproductive contributions?

Much of the contemporary study of adaptation in natural populations involves the regression of some component of fitness, usually survivorship or viability, on one or more characters of interest. It is difficult to apply this approach to measures of paternal reproduction, however, because paternity is typically estimated indirectly from genetic markers, rather than being measured directly from progeny counts. Here, we present maximum likelihood methods for modelling relative male reproductive success as a log-linear function of one or more potentially predictive features, as well as providing a framework for the assessment of pairwise (male:female) effects, as they affect male reproductive performance. We also provide nonparametric statistical tests for alternative models. Using this formulation, we examine the impact of inflorescence morphology on male reproductive success in Chamaelirium luteum L., and we also assess the importance of intermate distances between males and particular females. While male reproductive success and male inflorescence morphology are both quite variable, reproductive morphology does not appear to predict male reproductive success in this study. Intermate distance is an extremely effective predictor of pairwise success, however; but averaged over females, there is almost no net effect for different males.

Genetic Analysis of Male Reproductive Contributions in Chamaelirium Luteum (L.) Gray (Liliaceae)

Genealogical analysis is a powerful tool for analysis of reproductive performance in both natural and captive populations, but assignment of paternity has always been a stumbling block for this sort of work. Statistical methods for determining paternity have undergone several phases of development, ranging from straightforward genetic exclusion to assignment of paternity based on genetic likelihood criteria. In the present study, we present a genetic likelihood-based iterative procedure for fractional allocation of paternity within a progeny pool and apply this method to a population of Chamaelirium luteum, a dioecious member of the Liliaceae. Results from this analysis clearly demonstrate that different males make unequal contributions to the overall progeny pool, with many males contributing essentially nothing to the next generation. Furthermore, the distribution of paternal success among males shows a highly significant departure from (Poisson) randomness. The results from the present analysis were compared with earlier results obtained from the same data set, using likelihood-based categorical paternity assignments. The general biological pattern revealed by the two analyses is the same, but the estimates of reproductive success are only modestly (though significantly) correlated. The iterative procedure makes more complete use of the data and generates a more sharply resolved distribution of male reproductive success.
