Cycas brachycantha

A Vulnerable cycad endemic to Bắc Kạn Province in northern Vietnam, including Ba Bể National Park. It grows in soil-free cracks of limestone crests under evergreen forest. It has a short, often underground stem and leaves 1.4 to 2.5 m long. It wants filtered light, warm wet summers with a cool, drier winter, and a very free-draining mix.
