Cycas plants have spike-shaped strobilus at the apex (50 cm). Stamen strobilus is surrounded by numerous sporangia or microsporophylls. Microsporophylls are 3-5 cm long and 12-23 mm wide. The microsporophylls are spirally and densely arranged. It is flat, thick and scaly. Its base is narrow and its tip is wide. Anteriorly there is a triangular apophysis. Each microsporophyll contains numerous sporangia. 2-5 sporangia together form a sorus. Inside the sporangium is the spore mother cell. Each spore mother cell divides by the process of meiosis to produce spores or microspores. Microspores produce sperm. Spermatozoa of Cycas are Latim-like, multi-flagellated and the largest in the plant kingdom.
