Pandanus julianettii, also called karuka, karuka nut, or Pandanus nut, is a species of tree in the Pandanaceae family.[2]

Names

The specific epithet "julianettii" honors naturalist Amedeo Giulianetti, who found the original type specimens.[1]

In New Guinea it goes by different names among each of the Papuan peoples.[2] In the Ankave language it is xweebo.[2] It is yase in the Baruya language.[2] The Huli language word is anga, and it is also anga in the Duna language.[2] In Kewa language it is aga,[2] but it is unclear of this is in Erave (South Kewa), East Kewa, Pasuma (West Kewa), and/or the Kewa pandanus language. The plant is called ama in the Wiru language.[2] In the Pole language it's called maisene.[2] It goes by ank in Angal language.[2] The Imbongu language word is amo.[2]

Description

The species was originally described by Ugolino Martelli from only a few drupes in the collections of the Royal Botanic Gardens, Kew[1] He was hesitant to describe it as a new species from only that, but the characteristics we so salient he published his description.[1]

The clavate, pentagonal drupe measures 12 cm long and has a sharpened base.[1] The endocarp is bony and 5½ cm long, with rounded edges about 1½ cm wide.[1] The seed-bearing locule is around 4 cm long.[1] The top of the mesocarp fibrous, from 3 cm long and up.[1] Though Martelli did not have a complete syncarp, he knew the cluster of fruit must be large, estimating at least 30 cm in diameter.[1]

It most closely resembles Pandanus utilissimus, which is found the Philippines.[1]

Distribution

Giulianetti's type specimens were collected from Vanapa, British New Guinea[1] (now southern Papua New Guinea). The tree can be found cultivated or wild on New Guinea, both in PNG and Papua province.[2] It grows at high elevations.[2]

Ecology

Use by humans

On New Guinea it is cultivated crop.[2]
