FLORA OF BALI: A PROVISIONAL CHECKLIST

Compared to Java the flora of Bali is poorly known. A checklist has been prepared based on literature and collections. The focus is on indigenous species, but the distinction between indigenous and naturalized species is not always clear. This checklist is therefore very provisional. The flora of the much smaller island state Singapore is much richer, probably mainly due to undercollecting of Bali

Actephila alanbakeri (Phyllanthaceae) : A new nickel hyperaccumulating plant species from localised ultramafic outcrops in Sabah (Malaysia)

The Malaysian state of Sabah on the Island of Borneo is emerging as a hotspot for nickel hyperaccumulator species with at least 25 such species discovered to date. New discoveries of the hyperaccumulation trait in described taxa, as well as taxonomical novelties that are nickel hyperaccumulators, continue to be made. Here we describe a new nickel hyperaccumulating species of Actephila (Phyllanthaceae) originating from two known populations on ultramafic soils in Sabah. The most characteristic feature of Actephila alanbakeri are its knobbly fruits, but other diagnostic morphological characters are discussed and information about its ecology and rhizosphere and plant tissue chemistry is provided. This new species is one of the strongest known nickel hyperaccumulator plants in Southeast Asia with up to 14,700 µg g−1 (1.47 %) nickel in its leaves. The occurrences of Actephila alanbakeri on just two sites, both of which lie outside protected areas and are disturbed by recurring forest fires, combined with the small total numbers of individuals, render this species Endangered (EN) on the basis of IUCN Red List Criteria

Ultramafic nickel laterites in Indonesia (Sulawesi, Halmahera) : Mining, nickel hyperaccumulators and opportunities for phytomining

Indonesia (Sulawesi and Halmahera Islands) has some of the largest surface exposures of ultramafic bedrock in the world, and these are the sites of productive lateritic nickel mining operations. The proven and potential use of native plant species of ultramafic outcrops in mine rehabilitation can help drive conservation efforts, and nickel hyperaccumulators in particular can potentially be used in phytomining. The phytomining operation uses hyperaccumulators to extract residual nickel from stripped land. As such, in the foreseeable future, implementation of this technology is likely to be seen as a part of a progressive rehabilitation strategy of lateritic nickel mining in Indonesia. This approach ensures effective erosion control (e.g. 're-greening') while at the same time generating income by gaining residual nickel
