Rhopalostylis baueri

provided by wikipedia EN

Rhopalostylis baueri is a species of palm native to Norfolk Island (Australia) and to the Kermadec Islands (New Zealand). Norfolk Island is the type locality. The common names on Norfolk Island are 'Norfolk Island palm' or 'niau'. In New Zealand the name 'Kermadec nikau' is used to refer to the Kermadec Islands population.[1]

Distribution

R. baueri has a prominent crownshaft

On Norfolk Island it now occupies a small range in the centre of the island near the national park, where the species is somewhat threatened by rats that eat the fruit and young seedlings. It is rare elsewhere on the island. In the Kermadec Islands part of its range it is not threatened, but it only occurs on Raoul Island. Following the successful eradication of rats on Raoul Island, the palm has greatly extended its range. On Norfolk Island, which is still infested with rodents, R. baueri is regenerating and is abundant in some localities. If rodents were eliminated from Norfolk, the palm would benefit greatly.

Description and uses

Rhopalostylis baueri reaches 10 m or more in height. The pinnate leaves are 3 to 4 m long, on a stout, erect petiole (leafstem) approximately 20 cm long. The crownshaft is 50–60 cm long. The inflorescence is 30 50 cm long and has from 50 to 60 fairly stout branches. The fruits are green at first, turning a bright red when ripe, and are a favorite food of the endangered Norfolk Island parakeet. The growing tip of the palm was used by early settlers as a vegetable and is said to have tasted like a nut when raw and like an artichoke bottom when boiled.

Cultivation

Seedlings of R. baueri grown for sale in New Zealand

In the Southern Hemisphere outside its habitats, R. baueri is cultivated in mainland New Zealand as a faster-growing alternative to the otherwise similar R. sapida, the nikau palm, the only other species in the genus Rhopalostylis. It is also grown in the Australian states of New South Wales, Queensland, Victoria, and Western Australia. In the Northern Hemisphere excellent cultivated specimens are found on the coasts of the southeastern Azores and Madeira, which offer similar climates to those of the species' origin. The species is also grown outdoors in coastal California, Hawai'i, continental Portugal and Spain, the Canary Islands, and in parts of the Mediterranean basin (e.g., Palermo, Italy).

Notes

  1. ^ The palms native to Raoul Island in the Kermadecs, formerly described either as Rhopalostylis cheesemanii or R. baueri var. cheesemanii, were relegated to synonymy with the Norfolk Island R. baueri in 2005 after comparison showed no significant distinguishing characteristics (de Lange et al., 2005).

Rhopalostylis baueri ( Spanish; Castilian )

provided by wikipedia ES

Rhopalostylis baueri es una especie de palmera originaria de Isla Norfolk (Australia) y de Islas Kermadec (Nueva Zelanda). Su nombre común es 'Norfolk Island Palm' o 'Niau'. En Nueva Zelanda se llama 'Kermadec Nikau'.[1]

Descripción

R. baueri alcanza los 10 m de altura o más. Las hojas son pinnadas y de 3 a 4 m de largo, con un robusto y erecto pecíolo de aproximadamente 20 cm de largo. El capitel es de 50-60 cm de largo. La inflorescencia es de 30 a 50 cm de larga con 50 a 60 ramas bastante robusta. Los frutos son de color verde al principio, tornando un color rojo brillante cuando está maduro, y son el alimento favorito de la especie en peligro el perico de la isla de Norfolk.

Distribución

 src=
R. baueri

En la isla de Norfolk ahora ocupa un pequeño espacio en el centro de la isla, cerca del parque nacional, donde la especie está amenazada tanto por las ratas que se comen los plantones jóvenes y las frutas. Es raro en otras partes de la isla. En las Islas Kermadec, parte de su área de distribución no está amenazada, pero solo se produce en la Isla Raoul. Tras el éxito de la erradicación de ratas en la Isla Raoul, la palma se ha extendido mucho. En la isla de Norfolk, que todavía está infestado de roedores, R. baueri se regenera y es abundante en algunas localidades. Si los roedores fueran eliminados de Norfolk, la palma se beneficiarían en gran medida.

Cultivo

R. baueri

En el hemisferio sur, fuera de su hábitat, R. baueri se cultiva en el territorio continental de Nueva Zelanda como una alternativa de crecimiento más rápido a la otra similar R. sapida, el Palm Nikau, la otra única especie del género Rhopalostylis. También se cultiva en los estados australianos de Nueva Gales del Sur, Queensland, Victoria y Australia Occidental. En el hemisferio norte, excelentes ejemplares cultivados se encuentran en las costas del sureste de Azores y Madeira, que ofrecen climas similares a los de las especies de origen. Las especies también se cultiva al aire libre en la costa de California, Hawái, territorio continental de Portugal y España, las Islas Canarias, y en algunas partes de la cuenca mediterránea (por ejemplo, en Palermo, Italia).

Taxonomía

Rhopalostylis baueri fue descrita por (Hook.f.) H.Wendl. & Drude y publicado en Bot. Zeitung (Berlin) 35: 638. 1877[2]
