Notes on Taxonomy and Nomenclature

Top of page The recognition of A. colei as a distinct species resulted from recent research implemented by the Australian Tree Seed Centre (CSIRO, Forestry and Forest Products). The Centre has been actively involved in the collection, documentation and trialling of Australian Acacia species for use in developing countries since the 1980s (Midgley and Gunn, 1985; Turnbull, 1986; Thomson and Cole, 1987; House and Harwood, 1992; Thomson et al., 1994; Maslin and McDonald, 1996a; Doran and Turnbull, 1997). Much of the work focussed on acacias from the tropical dry zone of Australia due to their potential as sources of fuelwood and their ability to grow on difficult sites (see Thomson et al., 1994). Field trial results, however, revealed a number of Acacia 'taxa' that had substantial variation in morphological, biological and silvicultural characteristics, in particular A. holosericea (see McDonald et al., 1996 for others). Variation once considered part of A. holosericea was documented as comprising a polyploid species complex (Maslin and Thomson, 1992). A. colei (hexaploid) was segregated from A. holosericea (tetraploid) and another species, A. neurocarpa A. Cunn. ex Hook. (diploid), previously considered synonymous with A. holosericea, was reinstated. These species are superficially similar but differ in subtle morphological and ecological traits. A. colei differs from A. holosericea and A. neurocarpa in having phyllodes with shallowly recurved apices that lack a gland at the base of the apical mucro, distinctly elongated phyllode reticulum and curved pods (Maslin and McDonald, 1996a). It also differs in having a more southerly distribution and in not being restricted to a riparian habitat. The name honours E.G. Cole, a Senior Technician with the Australian Tree Seed Centre, who conducted early seed and botanical collections of the species.

Further investigations revealed A. colei comprised two distinct variants: var. colei and var. ileocarpa (McDonald and Maslin, 1997a). Although previously thought to have evolved as a putative hybrid involving A. colei (hexaploid) and A. neurocarpa (diploid) by Maslin and Thomson (1992), var. ileocarpa is also hexaploid but differs from var. colei in having tightly, irregularly coiled or twisted pods (which are very similar to those found in the related species A. holosericea and A. neurocarpa), orange-coloured terminal branchlets, slightly narrower phyllodes and smaller seeds (McDonald and Maslin, 1997a). The varietal epithet alludes to the twisted and coiled state of its pods.

A. colei, A. holosericea and A. neurocarpa belong to the Acacia section Juliflorae (Benth.) Maiden & Betche and form part of a group which includes A. cowleana Tate, A. elachantha M.W. McDonald & Maslin (see McDonald and Maslin, 1997b for a taxonomic reappraisal of these two species), A. grandiflora Pedley, A. mangium Willd., A. nesophila Pedley, A. pellita O. Schwartz, A. sericoflora Pedley and A. thomsonii Maslin & M.W. McDonald (Maslin and Thomson, 1992). All of these species occur in the seasonally dry tropics of Australia. They are characterized by their flowers in cylindrical spikes, phyllodes with numerous, anastomosing, longitudinal nerves and narrow, curved or tightly coiled and twisted pods with small seeds that have yellow or orange arils.

Based on morphological attributes and chromosome counts, Maslin and Thomson (1992) suggest that A. colei evolved as an allopolyploid between A. neurocarpa (diploid) and A. elachantha (a tetraploid). Maslin and McDonald (1996a, 1996b) suggest that the closest relative of A. colei is A. thomsonii Maslin & McDonald. Putative natural hybrids between A. colei var. colei and A. elachantha have been noted by Thomson (1992) and Maslin and McDonald (1996a). Kenneally et al. (1996) also note putative, natural hybrids between A. colei and A. neurocarpa in the Beagle Bay region of Western Australia.
