This new cycad is the oldest microstrobilus to our knowlege of cycads. In the same locality and layer, there are Primocy- cas chinensis Zhu et Du, Sphenophyllum emarginatum Brongn. , S. costae Sterz. , S. vertical- latum (Schloth.) Brongn. , S. oblongifolium (Germ. et Kaulf. ) Ung. , Tingia carbonica (Schenk.) Halle, T. hamaguchii Kon’no, Macrostachys huttoniformis Halle, Sphenopteris norinii Halle, S. firmata Sze, S. gothanii Halle, Sphenopteridium pseudogermanicum (Halle) Gu et Zhi, Pecopteris feminaeformis (Schloth.) Sterz. , P. wongii Halle, P. tuber- culata Halle, P. unita Brongn. , P. taiyuanensis Halle, Emplectopteris triangularis Halle, Taeniopteris norinii Halle, T. spp. , Cordaites principalis (Germ.)
