In addition, it is also known as Phoenix tail because its branches and leaves are like the Phoenix tail, and the tree trunk is like the trunk of plantain and pine trees. The growth is slow, the life span is more than 200 years, and a new leaf can be produced from the top of the stem every year.

The stem of the iron tree is 1 to 8 meters high. Stem Terete, unbranched. After the destruction of the growing point, it can sprout clusters of branches and buds under the wound, showing a multi-head shape. Leaf bases and leaf scars persistent on the stem, scalelike. Leaves grow from the top of the stem, 1-pinnately compound, 0.5-2.0 m long, thick leathery and hard, pinnae strip.
