| Abstract | We report a new species of the genus Weltrichia Braun with a special Bennettitalean male reproductive organ-W. daohugouensis Li et Zheng sp. nov., which was discovered from Haifanggou Formation (Middle Jurassic) in Daohugou Village, Shantou Town, Ningcheng County, Inner Mongolia (Nei Mongol) Autonomous Region, China. It is a unisexual male strobile which was a laterally compressed preserved specimen being fan-shaped and appearing as half of a whole. Its base and peduncle are lost while the lower part of the strobile consists of eleven narrowly wedged segments fused together into a funnel or cup-like. In the upper part of the strobile these segments separate into free structure (microsporophylls), each bearing two rows of pollen sacs (synangia). In this paper a new species W daohugouensis Li et Zheng sp. nov. is described and the identification of the W. huangbanjigouensis Sun et Zheng is emended. |
