Description

Aiphanes lindeniana is a small palm 1.5 to 7 m (4.9 to 23 ft) tall with stems 3 to 7 cm (1.2 to 2.8 ) in diameter, sometimes up to 10 cm (3.9 in) which are covered with black spines
Thorns, spines, and prickles
In botanical morphology, thorns, spines, and prickles are hard structures with sharp, or at least pointed, ends. In spite of this common feature, they differ in their growth and development on the plant; they are modified versions of different plant organs, stems, stipules, leaf veins, or hairs...

 up to 10 cm (3.9 in) long. Individuals are usually multi-stemmed, with up to 10 stems, but occasionally are single-stemmed. Stems bear 4 to 10 leaves which consists of a leaf sheath, a petiole
Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

 and a rachis
Rachis
Rachis is a biological term for a main axis or "shaft".-In zoology:In vertebrates a rachis can refer to the series of articulated vertebrae, which encase the spinal cord. In this case the rachis usually form the supporting axis of the body and is then called the spine or vertebral column...

. Leaf sheaths, which wrap around the stem, are 15 to 42 cm (5.9 to 16.5 ) long and are densely covered with black spines up to 12 cm (4.7 in) long. Petioles are 6 to 56 cm (2.4 to 22 ) long, and are covered with spines up to 8 cm (3.1 in) long. Rachises are 38 to 172 cm (15 to 67.7 ) and covered with spines. Leaves each bear 18 to 48 pairs of leaflets.

The male flowers, which are white to violet in colour, are 2 to 3 mm (0.078740157480315 to 0.118110236220472 ) long. The female flowers are slightly larger—3 millimetre long. The fruit are red or orange 14 millimetre in diameter.

 in 1857 as Martinezia lindeniana. In 1878 Wendland transferred it to the genus Aiphanes.
