Abstract

Premise of research. Malvaceae, or the mallows, are well known from the Cenozoic sediments of Asia and are represented by many fossil leaves, woods, fruits, and pollen. Until now, no fossil flower of Malvaceae has been reported from the Cenozoic sediments of Asia. The present study addresses this lacuna and documents the evidence of mallow fossil flowers from Asia for the first time. Methodology. Fossil flowers similar to modern flowers of Bombax L. (Malvaceae) were recovered from the latest Neogene (Pliocene) sediments of Chotanagpur Plateau, Jharkhand, eastern India. They were revealed by careful removal of the overlying matrix and studied under light microscopy. Pivotal results. The fossil flowers, characterized by irregularly lobed sepals, obovate-elliptic petals, numerous stamens bearing long filaments, and characteristic reniform anthers, are recognized as a new species, Bombax asiatica Hazra, Bera et Khan sp. nov. A morphological principal coordinates analysis and cladistic parsimony analysis based on floral morphological characters support this taxonomic assignment. Conclusions. This fossil evidence provides an important clue about the past diversity and paleobiogeography of the mallow family in the Indian Cenozoic. This finding and earlier reported Malvaceae fossils from the same locality also indicate the presence of tropical climate in Jharkhand, eastern India, during the time of deposition.

亚洲第一个锦葵花化石

研究的前提。Malvaceae，或称malmall，在亚洲的新生代沉积物中很有名，以许多树叶、树木、果实和花粉的化石为代表。到目前为止，在亚洲新生代沉积物中还没有发现锦葵科花的化石。本研究填补了这一空白，并首次记录了亚洲锦葵花化石的证据。方法。在印度东部贾坎德邦乔塔纳格布尔高原新近纪(上新世)沉积物中发现了类似于Bombax L. (Malvaceae)现代花的化石。通过仔细去除覆盖的基质，并在光学显微镜下研究了它们。关键的结果。Bombax asiatica Hazra, Bera et Khan sp. 11 .该花化石具有萼片不规则浅裂、花瓣倒卵形椭圆形、大量雄蕊长花丝、肾形花药等特征，是一个新种。基于花形态特征的形态主坐标分析和枝系简化分析支持了这一分类定位。结论。这一化石证据为研究印度新生代锦葵科过去的多样性和古生物地理提供了重要线索。这一发现和早期报道的来自同一地点的Malvaceae化石也表明，在沉积时期，印度东部的贾坎德邦存在热带气候。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
