Syagrus romanzoffiana

life science Maturity 5-7 Next article →

The queen palm, known scientifically as Syagrus romanzoffiana, is a medium-sized palm tree. It is also frequently called the cocos palm or the Jerivá. This species is native to South America, but it is grown globally as an ornamental garden tree. These palms are highly valued for their beauty in landscaping. They can grow quite tall as they reach maturity.

The structure of the queen palm is quite distinctive. It features pinnate leaves, which means the leaves have a feather-like shape. Each leaf is made up of many small parts called pinnae, or leaflets. While a typical leaf has around 300 pinnae, some can have as many as 494. These leaflets vary in length and width to create the lush appearance of the tree.

Scientific naming for this palm has been a complex process involving many experts. The tree was first described in 1822 in Paris. This description was published in a folio of illustrations by the artist Louis Choris. The text was written by the French-German botanist and poet Adelbert von Chamisso. Both men were part of a Russian scientific expedition led by Otto von Kotzebue. This expedition was funded by Nikolay Rumyantsev, a Russian Foreign Minister and Imperial Chancellor. The tree was named in his honor.

For a long time, the botanical identity of the queen palm was debated. In 1825, the Loddiges nursery in England imported seeds from Brazil. They called the plant Cocos plumosa in their catalogs. In 1859, a specimen at Kew Gardens flowered and produced fruit for the first time. This event helped botanists realize previous identifications were wrong. Joseph Dalton Hooker eventually published a valid description for the name Cocos plumosa in 1860. Later, in 1912, Alwin Berger classified Cocos plumosa as a variety of Syagrus romanzoffiana.

The queen palm plays a vital role in its local ecosystem. Many different animals rely on the tree for food. Birds such as the rufous-bellied thrush and the bananaquit eat the fruit pulp. Toucans like Ramphastos vitellinus pluck the fruit and then regurgitate the seeds. This process helps spread the seeds to new locations. Other mammals, including tapirs and the pampas fox, also interact with the fruit. Even the coati is an important seed disperser in certain areas.

However, some animals view the palm as a food source to be destroyed. The squirrel Guerlinguetus brasiliensis ingrami is a significant seed predator. It uses its teeth to break open the nutshell at one of three pores. This squirrel often targets nuts that are infested with bugs. Other insects, like the weevil Revena rubiginosa, also attack the developing seeds. Additionally, the larvae of the giant day-flying moth can eat the pith of the trunk. This damage is serious enough that it can kill the palm tree.

The distribution of the queen palm is vast. In its native range, it grows from Paraguay and northern Argentina to Brazil and Uruguay. It is very common in many Brazilian states, such as Rio de Janeiro and São Paulo. The tree has also spread to other parts of the world. It is naturalized in Florida and parts of the Mediterranean. In Australia, the state of Queensland views it as a potential invasive plant. Because of this, officials may discourage people from planting it in their gardens.
