    Notes: Summary The distribution and dynamics ofHaumaniastrum katangense (S. Moore) duvign. et Plancke (‘copper flower’) in southern Shaba Province, Zaïre have been studied. In the course of 20 years, this species has spread well beyond its original distribution. It is a successful coloniser of manmade environments containing mineralized substrates: i.e. disturbed or non-disturbed copper/cobalt deposits; copper/cobalt mining sites; sites of precolonial smelters; verges of dirt roads dressed with mine waste; along railways carrying ore wagons. The presence ofH. katangense along the verges of railways and roads, explains the expansion of its distribution in modern times, however its occurrence over sites of precolonial copper smelting operations is of great importance in archaeology.

    Copper and cobalt uptake by metallophytes from Zaïre (1979)
    Springer
    Plant and soil 53 (1979), S. 535-539 
    Details
    ISSN: 1573-5036
    Keywords: Aeolanthus ; Cobalt uptake ; Copper uptake ; Haumaniastrum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Pot trials were carried out on plants ofHaumaniastrum katangense, Haumaniastrum robertii andAeolanthus biformifolius. These metallophytes from Zaïre were grown in substrates containing from 0–10,000 μg/g (0–1%) copper or cobalt. The tolerance of each species was determined and for cobalt was highest inH. robertii (4000 μg/g) and for copper was highest inAeolanthus biformifolius (9000 μg/g). Discontinuities in the plant-soil curves for each element indicate an exclusion mechanism operating for all three species at lower concentrations of the element in the soil. All species would grow in soils containing only traces of cobalt or copper and this indicated that uptake of heavy metals was not linked to a physiological requirement for either element. The plant-soil relationship for cobalt (P〈0.001) was sufficiently good for all three species for them to be useful in biogeochemical prospecting for this element.
