ruffle palm, coyure palm
Stems: Solitary, upright, grayish stems to 10 m tall and up to 15 cm in diameter, ringed with flattened black spines (up to 2 cm long) and leaf scars. Leaves: Pinnate, with a short, spiny petiole and drooping, spiny rachis. Leaflets, clustered in groups of 4-6, grow in several planes, and the praemorse tips have three major teeth. The wedge-shaped leaflets are dramatically wider at the leaf apex. The blades may be glabrous to more or less covered with small spines. Flowers and fruits: Inflorescences (about 60-90 cm long) are borne among the leaves and are once branched. Separate staminate and pistillate (male and female) flowers are held on the same inflorescence. Fruits are spherical, 1.6-2.3 cm, and bright red or orange-red when ripe.
Lab: Spines on new leaves may be covered with grayish white tomentum.
Aiphanes minima is similarly spiny, but its leaflets are more or less lanceolate, widest at the midpoint and gradually tapering toward the base and praemorse tip while Aiphanes horrida has wedge-shaped praemorse leaflets with a ruffled appearance.
