根据新疆中泥盆统的挤压化石，建立了一个新的草本石松类种Leclercqia uncinata Xu，Berry，Wang et马歇尔。新种具有细长的轴和三维，七尖叶，具有与该属的原始诊断一致的远端钩状中央节，它相对于模式种，L.来自纽约州的复形藻。孢子囊内含有孢子，可归属于形态分类群Acinoporites lindlariensis。在我们的压缩准备，iridopteridale可育附属物被发现困在远端钩叶L。钩状的文中还讨论了该新植物可能的攀援习性。
A new herbaceous lycopsid species, Leclercqia uncinata Xu, Berry, Wang et Marshall, is established on the basis of compression fossils from the Middle Devonian of Xinjiang, NW China. The new species has slender axes and three-dimensional, seven-tipped leaves with a distally hooked central segment conforming to the original diagnosis of the genus, and it is relatively smaller than the type species, L. complexa from New York State. The sporangium contains the spore, which can be assigned to morphotaxon Acinoporites lindlariensis. In our preparation of compressions, iridopteridalean fertile appendages are found trapped between the distally hooked leaves of L. uncinata. A possible climbing habit of the new plant is discussed.
