Allagoptera produces very short or acaulescent trunks and in cases where the trunk grows erect it often makes a downward turn leaving the crown below the trunk-base. The trunks in Allagoptera are among the few in the palm family which tend to bifurcate, producing multiple heads per unit. The pinnate leaves are gently arching to 2 m and are carried on long, slender petioles which are adaxially channeled. The single-fold leaflets are regularly or irregularly arranged on the rachis each protruding into a different plane, creating a plumose leaf. The unusual spicate inflorescence emerges from within the leaf-crown carrying the pistilate flowers basally with the staminate flowers growing distally. The single-seeded fruit is yellow to brown, growing in crowded clusters.[4]
