Aiphanes eggersii, known locally as corozo, [1] is a species of spiney, pinnately leaved palm which is native to the coastal plain of Ecuador and adjacent dry forests of Peru. [1] [2]

Description

Aiphanes eggersii is a small, multi-stemmed palm 1 to 6 metres (3.3 to 19.7 ft) tall with up to 10 stems. Stems are 7 to 8 cm (2.8 to 3.1 in) in diameter. Stems are covered with black or grey spines up to 10 cm (3.9 in) long. Individuals have between 7 and 10 leaves which consists of a leaf sheath, a petiole and a rachis. Leaf sheaths, which wrap around the stem, are about 40 to 75 cm (16 to 30 in) long and are covered with black or grey spines up to 10 cm (3.9 in) long. Petioles are 0 to 10 cm (0.0 to 3.9 in) long and spiny. Rachises are 115 to 205 cm (45 to 81 in) with 50 to 65 pairs of leaflets (or more rarely as few as 30 pairs). [1]

Inflorescences consist of a peduncle 42 to 137 cm (17 to 54 in) and a rachis 35 to 48 cm (14 to 19 in) long. The rachis bears 35 to 75 rachillae, which are the smaller branches which themselves bear the flowers. Flowers are borne in groups consisting of one female and two male flowers. The male flowers are yellow, while the female flowers are yellow with brown sepals. The ripe fruit is bright red, spherical, and 18 to 22 millimetres (0.71 to 0.87 in) in diameter. [1]

Taxonomy

Aiphanes has been placed in the subfamily Arecoideae, the tribe Cocoseae and the subtribe Bactridinae, together with Desmoncus , Bactris , Acrocomia and Astrocaryum . [3] In his 1932 revision of the genus, German botanist Max Burret placed Aiphanes eggersii in the subgenus Macroanthera, one of the two subgenera into which he divided the Aiphanes. In their 1996 monograph, Finn Borchsenius and Rodrigo Bernal recognised that if Macroanthera was reduced to three species ( A. horrida , A. minima , and this species) it could form a viable grouping, but that this would leave the other subgenus, Brachyanthera overly heterogeneous, and consequently the abandoned Burret's use of subgenera. [1]

Aiphanes eggersii was described by Burret in 1932 based on collections made by Danish botanist Henrik Franz Alexander von Eggers in February 1897. The generic epithet, Aiphanes, coined by German botanist Carl Ludwig Willdenow in 1801, derives from Greek ai, meaning "always" and phaneros, meaning "evident", "visible" or "conspicuous". [1] The specific epithet, eggersii, honours Eggers. [1]

Reproduction

The flowers of A. eggersii produce small quantities of nectar, but lack a scent. Male flowers open once the inflorescence is freed from the bract in which it develops. They last eight to ten days. Female flowers open about a week after the male flowers, and last for another week. The flowers are visited by bees and wasps and contained micromoth larvae; they are believed to be pollinated by bees, with a possible contribution from the wind. [1]

Distribution and habitat

Aiphanes eggersii is native to the dry forests of the coastal plain of Ecuador and northern Peru, [2] in areas receiving as little as 500 millimetres (20 in) of precipitation annually.[ citation needed ] It is commonly found in the Ecuadorian province of Manabí. [1]

Uses

The fruit and seeds are edible, and trees are sometimes planted near houses. [1]

<i>Bactris</i> Genus of palms

Bactris is a genus of spiny palms which are native to Mexico, South and Central America and the Caribbean. Most species are small trees about 2 m tall, but some are large trees while others are shrubs with subterranean stems. They have simple or pinnately compound leaves and yellow, orange, red or purple-black fruit. The genus is most closely related to several other spiny palms—Acrocomia, Aiphanes, Astrocaryum and Desmoncus. The fruit of several species is edible, most notably B. gasipaes, while others are used medicinally or for construction.

<i>Aiphanes</i> Genus of spiny palms native to tropical South and Central America and the Caribbean

Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean. There are about 26 species in the genus, ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 metres (66 ft). Most have pinnately compound leaves ; one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and mammals, including at least two species of amazon parrots.

<i>Roystonea</i> Genus of palms

Roystonea is a genus of eleven species of monoecious palms, native to the Caribbean Islands, and the adjacent coasts of the United States (Florida), Central America and northern South America. Commonly known as the royal palms, the genus was named after Roy Stone, a U.S. Army engineer. It contains some of the most recognizable and commonly cultivated palms in tropical and subtropical regions.

<i>Aiphanes horrida</i> Species of palm

Aiphanes horrida is a palm native to northern South America and Trinidad and Tobago. Aiphanes horrida is a solitary, spiny tree. In the wild it grows 3–10 metres tall tall with a stem diameter of 6–10 centimetres ; cultivated trees may be as much as 15 m (49') tall with a 15 cm (6") diameter. The epicarp and mesocarp of the fruit are rich in carotene and are eaten in Colombia, while the seeds are used to make candles. In parts of the Colombian Llanos endocarps are used to play games.
