Callitris sulcata is a plant from the family of the cypress family (Cupressaceae). This endemic occurs only on the island of Grande Terre .

description

Callitris sulcata grows as an evergreen tree that can reach heights of 5 to 15 meters. The trunk is twisted. The smooth bark flakes off in irregularly shaped pieces.

Young leaves are elongated and can be pointed. Older leaves are triangular in shape.

The male cones are at the end of the branches and are 3 to 5 millimeters long and 1.5 to 2 millimeters thick. The female cones are at the end of the branches and are about 1 centimeter long and 1 centimeter thick. The seeds are shaped like a pyramid.

Distribution and location

The natural range of Callitris sulcata is in the southern province , on the island of Grande Terre , which belongs to New Caledonia . It extends there along the Tontouta , Dumbéa and Comboui rivers .

Callitris sulcata thrives at altitudes of 40 to 200 meters. The species is found there mainly in dense forests on ultramafic soils .

Callitris sulcata is classified as "critically endangered" in the IUCN Red List . Although the distribution area extends over an area of ​​around 226 km², only about 20 km² of it are populated with stocks of Callitris sulcata . The total population is estimated at less than 2500 fully grown trees, with none of the individual populations consisting of more than 250 trees. The number of trees is decreasing and the species is being considered "critically endangered" in the future. Forest fires and logging in connection with poor regeneration are given as the main risk factors.

use

The wood gives off a strong smell reminiscent of camphor and is very resistant to rot and insect attack. It was previously used to build wooden houses and later also to make railway sleepers. The wooden posts from old houses are still used today to design new buildings. In 2001, to commemorate the renovation of the church in St. Joseph de Borendi, six barked trunks were erected in a nearby holy place. These are said to be a symbol for the six clans of the local tribes that are connected to the church.

Systematics

The first description as Frenela sulcata was in 1862 by Filippo Parlatore in Index Seminum (FI) , page 23. Rudolf Schlechter transferred the species in 1906 in Botanical Yearbooks for Systematics, Plant History and Plant Geography , Volume 39, page 16 as Callitris sulcata in the genus Callitris .
