Discussion

  • Caespitose, stem and leaves similar in size and form to I. wallichiana var. wallichiana, inflorescence also similar, but differs and is distinct in its fruit colour, pink when immature ripening dark pink or red. Two specific colonies, in Perak and Kelantan, were found to display the consistent fruit colour distinction. The drupes are globose or ovoid and similar in size to I. wallichiana, and also in the carriage and branching of the inflorescence. Both populations studied over a twoyear period are locally abundant, relatively robust. some with stems to 4m in height, with large leaves to 1.5m. pinnate with broad or narrower leaflets. We have so far not encountered intermediaries in colour in other locations, and believe that this character can be used for varietal differentiation.
    The fruit colour distinction has also been displayed by another new species, I. asli. Although the variation had been considered as "minor local differences" within I. wallichiana and I. geonomiformis by Kiew (1976: 221), the forms she mentioned as seen in Taman Negara and elsewhere with pink immature fruit, might well have been that new species, which has other distinctions in its inflorescence. I bclieve that further surveys will locate other consistent populations?of this taxon. (Lim C.K. 1996. Unravelling Iguanura Bl. (Palmae) in Peninsular Malaysia.
