Livistona endauensis

Livistona endauensis is a species of palm tree of the genus Livistona . It is a tree endemic to Peninsular Malaysia. [1] [3] It has been called Endau fan palm in English. In Malay the palm is known as bertam or serdang Endau. [3]

Taxonomy

Livistona endauensis was recognised as a new species relatively recently, being described in 1987 by John Dransfield and Khoon Meng Wong in an article published in the Malayan Nature Journal. The holotype was collected by Dransfield at 400 metres in altitude in 1977 on the Gunong Janing ('Janing mountain'), a mountain in the state of Johor, and has the collection number JD#5089. It is housed at the herbarium at Kew Botanical Gardens, with an isotype kept at the herbarium at the Forest Research Institute Malaysia in Kepong. [2]

Description

The seed is round and about 1 cm in diameter; the testa intrudes shallowly into its surface. The eophyll, which is the first fully-expanded leaf of a seedling palm, has five ribs. [4]

Ecology

It is found in lowland open and closed forests. [1] In the jungles where it occurs, it is found in a specific habitat on edaphically marginal, infertile soils on slopes, ridges and on hill tops. In such places it is a dominant part of the vegetation, but only in some areas. This is thought to very likely be due to being specialised on growing in sedimentary soil derived from granite or igneous rock from the Jasin complex. Other often conspicuous trees associated with this habitat are the dipterocarps Cotylelobium lanceolatum and Shorea blumutensis . [5]

It is found in an area where there were still a relative number of wild rhinos in the 1970s. [5]

Conservation

In 1998 it was assessed as a 'near threatened' species in the IUCN Red List, because its populations were severely fragmented, and there was a decline of mature individuals at the time. [1] It was not evaluated in the Malaysia Plant Red List , published 2010. [3] A population is protected in the Endau-Rompin National Park. [5]

<i>Saribus brevifolius</i> Species of palm tree

Saribus brevifolius is a species of palm tree in the genus Saribus, which has only been found in the Kawe and Gag Islands in the archipelago of the Raja Ampat Islands, which lie off the north-west tip of the Bird's Head Peninsula in Indonesia's West Papua province. It was only discovered in 2002 during an expedition funded by The Nature Conservancy. The palm grows along the coasts of these two tropical islands on small ridges composed of ultrabasic rock. It is a moderately-sized fan palm with smallish and regularly segmented leaves and a smallish inflorescence in the crown. The inflorescence is not longer than the leaves, and split at its base into three main branches with one or more sub-inflorescences, these containing red flowers with pink anthers. The ends of S. brevifolius leaf segments are rigid and have a bifurcate cleft 1-4% of the segment length.
