TYPE SPECIMENS OF INULA (PITYOPSIS) GRAMINIFOLIA (ASTERACEAE: ASTEREAE)

Abstract : Recent proposed changes to the nomenclature of the goldenaster genus Pityopsis disagreed significantly on the application of the name Inula graminifolia, the basionym of Pityopsis graminifolia. In order to clarify the problem, the three known collections of Inula graminifolia in the Herbarium of the Muséum national d'Histoire naturelle, Paris (P) collected by André Michaux were examined. The holotype collection has small heads with many stipitate glands on the distal portion of the phyllaries and obvious long hairs on the peduncles. This is also the case for the isotype collection. A third collection by Michaux is mixed with a shoot with larger heads and shoots with smaller heads and all with phyllaries with few or no stipitate glands. Thus, the third specimen is not part of the same taxon as the holotype and isotype.
