Habitat and Distribution

Burretiokentia dumasii is found in the rainforests, of New Caledonia. Occurs in rainforest on ultramafic rocks.
Big Island, Hawaii.
Burretiokentia dumassii is mostly on rocky, well drained sites on oxysols derived from peridotites. 600-1100 m elevation. This species is known only from the Mainland to Nodéla, on the western slope of Mémaoya. Habitat: In rain forest on steep slope. Substrate: Eroded soil on scree on ultramafic substrate.

New Caledonia. Burretiokentia dumasii is known only from collections in Nodela Valley on the Me Maoya massif north of Bourail in west-central New Caledonia, at 600 m elevation. According to observations and photographs by J-P. Tivollier, however, it may also grow above Emma Mine on the ridge leading to Me Maoya summit at 1100 m elevation, and if so, it probably occurs elsewhere on the massif. A collection at Foret de Saille, south of Thio. in southeast New Caledonia may represent the same species. In that case, B. dumasii may be relativeIy widespread. Burretiokentia dumasii occurs in rain forest on ultramafic rocks. It is found mostly on rocky, well-drained sites on oxysols derived from peridotites. (J-C. Pintaud and D. Hodel. 1998)/Palmweb.

Comments and Curiosities

PHENOLOGY: Burretiokentio dumasii flowers in September and fruits in January.

CONSERVATION STATUS (lUCN, 1994): Low risk, conservation-dependent (LRcd). The type and only documented locality in Nodela Valley has been recently declared a Special Reserve of Flora and Fauna. The Forestry Service of Bourail manages and controls access to the reserve. Thus, although very rare, B. dumasii is adequately protected. This palm is abundant where it grows and regeneration is good. (J-C. Pintaud and D. Hodel. 1998)/Palmweb.

TAXONOMIC HISTORY: J.-M. Veillon of ORSTOM and Serge Blancher of the Forest Service found Burretiokentia dumasii in 1992 when the Forestry Service began to manage the forests of Nodela. A private company had partially logged Nodela Valley prior to 1992. (J-C. Pintaud and D. Hodel. 1998)/Palmweb.

ETYMOLOGY: The name honors Marc Dumas, an ardent palm enthusiast who has greatly contributed to the study of New Caledonian palms in recent years and who helped in raising a new and strong interest in palms in New Caledonia with the founding of Association Chambeyronia, of which he is currently president. (J-C. Pintaud and D. Hodel. 1998)/Palmweb.
