Abstract

A herbarium collection of plants from Obi Island (North Moluccas) was analyzed for nickel and other elements in order to identify new hyperaccumulators (> 1000 μg/g dry weight) which are indicative of ultrabasic substrates. Ultrabasic substrates are usually hosts for important economic minerals. Planchonella oxyedra Dubard and Trichospermum kjellbergii Burret were found to be hyperaccumulators of nickel and the work was therefore followed up by analysis of further specimens of these two species from localities throughout their range in Southeast Asia and Oceania. The data pinpointed previously known ultrabasic areas in Sulawesi (Celebes) and West Irian (Indonesian New Guinea) as well as one in Ambon (South Moluccas) which is not recorded on geological maps.

    Analysis of herbarium specimens originating from Indonesia led to the discovery of the following Ni hyperaccumulator plant species: Rinorea bengalensis, R. javanica (Violaceae), Trichospermum kjelbergii (Tiliaceae), Planchonella oxyhedra (Sapotaceae), Myristica laurifolia var. bifurcata (Myristicaceae), Brackenridgea palustris subsp. kjellbergii (Ochnaceae), Psychotria sp. (Rubiaceae), Phyllanthus insulae-japen and Glochidion aff. acustylum (Phyllanthaceae) (Wither and Brooks, 1977; Reeves, 2003). More recently, fieldwork in Sulawesi recorded Sarcotheca celebica (Oxalidaceae) and Knema matanensis (Myristicaceae) as Ni hyperaccumulating taxa (Tjoa, pers.

    The same procedure was repeated and Trichospermum kjelbergii, Planchonella oxyhedra and Myristica laurifolia var. bifurcata were also determined to be hyperaccumulators from herbarium specimens by Wither and Brooks (1977) without ever actually visiting Indonesia. Reeves (2003) used the same method and added Brackenridgea palustris ssp. kjellbergii (Ochnaceae), Psychotria sp. (Rubiaceae), Phyllanthus insulae-japen and Glochidion aff. acustylum (Phyllanthaceae) to the growing list.
