Dissertation Research: Systematic Monograph, Cladistic Analysis and Biogeography of the Neotropical Salacia, Species Group Ellipticae (Hippocrateaceae)

9311097绅士和塔尔博特在热带植物迷人的生长形式中，藤本植物或木本藤本植物在森林中很常见，具有重要的生态意义。它们在分类学上的研究也很少，部分原因是难以从林冠高处获取开花和结果材料。研究生塔尔博特在金特里博士的指导下，正在研究希波克拉特科沙拉西亚属的新大陆物种，主要是藤本植物和小乔木，在南美洲北部地区有非常多样化的花型。对保存标本的植物标本馆研究将得到巴西、秘鲁和厄瓜多尔的广泛实地工作的补充，以获取新材料并观察授粉和种子传播。通过对花粉和叶表面的扫描电子显微镜的使用，将在传统的解剖和形态特征的基础上获得新的形态特征。热带物种的多样性仍然很少被认识或记录，特别是对于藤本植物或木本藤本植物，那里的花和果实很难从高高的森林树冠上采集。这项研究将集中在柳属植物上，并将提高我们对物种识别、物种之间的系统发育关系以及地理分布和特有模式的理解。***

9311097 Gentry and Talbot Among the fascinating growth forms of tropical plants, lianas or woody vines are common in forests and ecologically important. They are also poorly studied taxonomically, in part because of difficulties in procuring flowering and fruiting material from high in the forest canopy. Graduate student Talbot under the supervision of Dr. Gentry is studying the species of the New World genus Salacia of the family Hippocrateaceae, mostly lianas and small trees, with a great diversity of floral form in regions of northern South America. Herbarium study of preserved specimens will be supplemented by extensive field work in Brazil, Peru, and Ecuador to acquire new materials and to make observations on pollination and seed dispersal. New morphological characters will be acquired through use of scanning electron microscopy of pollen and of leaf surfaces, adding to traditional anatomical and morphological features. %%% The diversity of species in the tropics is still little appreciated or documented, and in particular for lianas or woody vines, where flowers and fruits are difficult to collect from the high forest canopy. This research will focus on plants of the genus Salacia and will improve our understanding of species recognition, phylogenetic relationships among the species, and patterns of geographical spread and endemism. ***
