摘要

摘要天南星科植物具有物种多样性高、习性多样性高、特有率高、新种发现率高的特点。讨论了该科早白垩纪的起源及其现代在世界范围内的分布，在亚洲表现出高度的属多样性，在南美洲表现出高度的种多样性。在过去的40年里，大多数新热带属的已知物种数量急剧增加，但大部分增长来自中美洲。计算机化测定键的发展使人们认识到，更多的物种可能是科学上的新物种。本研究还建议了今后应集中研究的方向和地点或地区。

Araceae, a Family with Great Potential1

Abstract This paper highlights the most unique characteristics of Araceae: their high species diversity, high habit diversity, high rates of endemism, and high rates of new species discovery. Also discussed is the origin of the family in the Early Cretaceous period and its modern-day worldwide distribution, which shows high generic diversity in Asia and high species diversity in South America. The last 40 years have shown dramatic increases in the number of species known for most of the Neotropical genera but with most of the growth coming from Central America. The development of computerized determination keys has led to the realization that many more species are likely to be new to science. This study also recommends future directions and localities or regions where most aroid research should be concentrated.

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
