Etymology
The name is derived from the Greek word lepis (λεπίς) meaning scale,[2] which refers to the scale-like structure of the stem and leaf bases.
Species
| Image | Scientific name | Distribution | Leaf | Cone |

 | Lepidozamia hopei (W.Hill) Regel | northern Queensland |  |  |
 | Lepidozamia peroffskyana Regel | southeastern Queensland, northeastern New South Wales |  |  |
A specimen of L. hopei is known as the tallest living cycad at 17.5 m tall. These cycads are generally unbranched, tall, and with persistent leaf bases. They are easily cultivated as ornamental plants and are relatively cold hardy; L. peroffskyana was first described by a specimen grown at St. Petersburg's botanical garden in 1857.
