It is a shrub with many thorns and branches. It can grow up to 3 metres high.
The leaves are very small, and it has two types of thorns: some are wider, in the shape of a cross or anchor, and the others are more narrow.
The flowers are white and have no petals. They come together in groups of 6 and have a scent reminiscent of almonds.
You will find 2 specimens in the Chile bush area, next to the cliff path, which mark the entrance to the stairs. The largest is over 2 metres high.
