Macrozamia macdonnellii, also known as the Macdonnell Ranges Cycad, is a species of cycad native to the Northern Territory of Australia. It is characterized by large, bluish-green pinnate leaves that emerge from a stocky trunk, and distinct male and female cones. The seeds are egg-sized with a bright red outer layer.

About Macrozamia macdonnellii
The Macrozamia macdonnellii, commonly known as the MacDonnell Ranges Cycad, is a distinctive species of cycad native exclusively to the Northern Territory of Australia. It is a member of the Zamiaceae family.
Botanical Description
This species is characterized by its stocky trunk, from the top of which a crown of large, frond-like pinnate leaves emerges. These leaves are notable for their bluish-green coloration. Macrozamia macdonnellii is dioecious, meaning that male and female reproductive cones are borne on separate plants. The female cones are broader than their male counterparts and partially enclose the seeds. These seeds are approximately egg-sized and are distinguished by a vibrant red outer layer, or sarcotesta.
Ethnobotany and Ecology
While indigenous to the region, the Macrozamia macdonnellii is not commonly consumed by the Arrernte people of the Macdonnell Ranges. This is due to the significant and extensive process of toxin leaching that is required to render the plant safe for consumption, highlighting its inherent toxicity in its natural state.
