''Aiphanes minima'' is a spiny palm tree which is native to the insular Caribbean from Hispaniola to Grenada, and widely cultivated elsewhere. Usually tall, it sometimes grows as an understorey tree and only in height.
==Description==
''Aiphanes minima'' is a single-stemmed, spiny palm with pinnately compound leaves—rows of leaflets emerge on either side of the axis of the leaf in a feather-like or fern-like pattern. Stems are usually tall, though occasionally as little as tall and in diameter. Younger stems are covered with rings of black spines, but on older stems these are often lost. Individuals bear 10–20 leaves which are pinnately compound, bearing 18 to 34 pairs of leaflets along a central rachis that is long. The leaflets are borne in a single plane, and are usually linear in shape, but sometimes widen towards their apex, especially in Puerto Rico. The lower surface of the leaf can be covered with spines up to long or can be unarmed; the upper surface has a row of spines about long along the midrib. The rachis can be unarmed but is often covered with black spines up to long. The petiole, which connects the rachis with the stem, is long and covered with black spines up to long.〔Borchsenius & Bernal (1996), pp. 71–75〕
