Ptychosperma elegans, commonly known as the solitaire palm (or elegant palm after the scientific name), is a very slender palm endemic to Queensland in Australia. In the nursery trade and in the United States it may be confusingly referred to as Alexander palm, which is an often-used but misnomered name of another Australian palm species Archontophoenix alexandrae, the Alexandra palm (note the difference in gender between the two names).
