Zusammenfassung:For Australian Aboriginal people plant resins have played an important role in both trade and the manufacture of hafted tools. In particular, the resins of the Xanthorrhoea species were widely distributed and favored resources. The aim of this pilot study was to: (1) determine if starch grains were present in all of the Xanthorrhoea resin samples examined, and (2) determine the feasibility of discriminating between resins of different Xanthorrhoea species by the morphological attributes of their starch grains. The results established that starch grains were present within all of the Xanthorrhoea species resins that were examined. Moreover, for the purpose of identifying resins from within this genus the preliminary results suggest that starch grains have sufficient differences in attributes to allow discrimination between species. The results suggest that further research into the morphological attributes of starch grains in resins may prove to be an efficient and cost-effective means by which species identification could be achieved for small portions of archaeological resin samples. /// Las resinas de las plantas han tenido un papel muy importante para los Aborigenes Australianos en el intercambio y en la manofactura de herramientas con mangos. En particular, las resinas de las especies Xanthorrhoea eran recursos ampliamente distribuidos y preferidos. El objetivo de este estudio piloto fue: 1) establecer si los granos de almidon estaban presentes en todas las muestras estudiadas de resina de Xanthorrhoea y 2) determinar la factibilidad de discriminacion entre las resinas de diferentes especies mediante los atributos morfológicos de sus granos de almidón. Los resultados establecieron que los granos de almidón se encontraban presentes en todas las especies de resina Xanthorrhoea examinadas. Ademas, para este proposito de identificar resinas desde dentro del genero glos resultados preliminares sugieren que los granos de almidón tienen suficientes diferencias en atributos para permitir la discriminación entre las especies. Los resultados indican que futuras investitigaciones dirigidas a las caracteristticas morfológicas de los granos de almidón en las resinas pueden ser un medio eficiente y barato a través del cual se puede lograr la indentificacion de especies.
