Generic Segregation of Pithecellobium and Revision of Abarema and Macrosamanea (Leguminosae)

分类学研究是基本工具， 对物种的进化、生态学和其他生物学研究 可以实现。此外，为了研究濒危物种， 对于目前正在编制的众多生物清单， 错误识别或误解，未记录的发现， 错误的物种名称会造成混乱和灾难。 纽约植物园的鲁珀特·巴内比博士和他的 我的同事詹姆斯·格莱姆斯博士正在进行一项基本的分类学研究 属于热带豆科植物木豆属和其他属 与之相关，试图找到稳定的形态学 这些特征将允许可靠地识别所有物种。 他们将在南美洲进行实地考察， 材料，以补充现有的植物标本，他们 将增加花粉扫描电子显微镜的新数据， 在这些植物中显示出广泛的变异。开始 该项目，他们将集中在一些分离的属， 50种左右，在处理整个属之前，估计 包括超过160种，主要分布在新大陆的热带地区。 在纽约植物园的资源是极好的， 项目

Taxonomic research is the basic tool by means of which all evolutionary, ecological, and other biological studies on species can be accomplished. Also, for studies of endangered species and for the numerous biological inventories now in preparation, misidentifications or misinterpretations, undocumented findings, and incorrect species names can produce confusion and disaster. Dr. Rupert Barneby of the New York Botanical Garden and his colleague Dr. James Grimes are conducting a basic taxonomic study of the tropical legume genus Pithecellobium and other genera associated with it, in an attempt to find stable morphological features that will permit reliable identification of all species. They will conduct field work in South America to gather new material, to supplement existing herbarium specimens, and they will add new data from scanning electron microscopy of pollen, known to show extensive variation among these plants. To begin the project, they will focus on a number of segregate genera with 50 or so species, before tackling the whole genus, estimated to include over 160 species, mostly in the New World tropics. Resources at New York Botanical Garden are excellent for this project.
