摘要

The taxonomic position of fossil woods suggested to be related to Bischofia is reassessed based on the examination of the wood anatomy of recently collected samples of its two modem species (B. javanica and B. polycarpa). Woods of B. palaeojavanica from the middle Pliocene of India, and B. javanoxyla from the early Miocene of northern Taiwan have features of extant B. javanica. In contrast, the Eocene Bischofia maomingensis (South China) differs from Bischofia in a number of features and we propose a new combination Chadronoxy- lon maomingensis (Feng et Jin) Oskolski, Stepanova, Huang et Jin. Bischofia palaeojavanica from the latest Cretaceous-earliest Paleocene Deccan Inter-trappean Beds, India, and all other pre-Miocene woods assigned to Bischofia differ from extant Bischofia in vessel diameters, vessel element lengths, inter-vessel pit sizes, position of vessel-ray pits, and/or abundance of sheath cells in rays. Therefore, their generic position must be reconsidered, and there is no reliable record of Bischofia wood older than Miocene.

Javanica的特点。相比之下，艾茂碧雪索毛明根（华南）与碧雪亚比亚在许多功能中不同，我们提出了一个新的组合Chadronoxy- Lon Maomingensis（Feng et Jin）Oskolski，Stepanova，Huang et Jin。 Bischofia Palaeojavanica来自最新的白垩纪最早的古世纪Deccan Inter-appean床，印度和分配给Bischofia的所有其他前普通树木不同于血管直径，血管元件长度，血管内坑尺寸，容器射线的位置不同凹坑和/或丰富的鞘细胞在光线中。因此，必须重新考虑它们的通用位置，并且没有比新世的双思卓木的可靠记录。
