Abstract
SummaryBartoli, A. & Tortosa, R. D.: Intermediacy between Grindelia chiloensis and Haplopappus pectinatus (Astereae, Asteraceae). – Taxon 47: 337‐345. 1998. – ISSN 0040‐0262.Intermediate specimens between Grindelia chiloensis and Haplopappus pectinatus occur in Patagonia (Argentina). They were analysed using the methods proposed by Wells (distance diagram) and Wilson (character count procedure). With both methods the hypothesis of hybridity is supported. A close proximity of H. pectinatus to the genus Grindelia is also suggested by a high percentage of stainable pollen grains in the putative hybrids, chromosome morphology, and achene anatomy. Based on such evidence, the new combination G. anethifolia (H. pectinatus Phil., non G. pedinata Baker) is proposed.
