High Quality Content by WIKIPEDIA articles! Syagrus romanzoffiana (Queen Palm or Cocos Palm) is a palm native to South America, from northern Argentina north to eastern Brazil and west to eastern Bolivia. It is very similar to the coconut palm. It had been classified within the Cocos genus as Cocos plumosa, was assigned to Arecastrum, then moved to Syagrus. As a result of the nomenclature confusion, they often retain a previous, incorrect name in popular usage. It is a medium-sized palm, growing to 15 m tall, with pinnate leaves.
