Türkiye Florası İçin Yeni Bir İstilacı Bitki Kaydı: Grindelia hirsutula Hook. & Arn.

Many invasive plant records have been given in Turkey in recent years. Some of these are considered as escapees from garden or farm when they have medicinal properties and economic value. Grindelia hirsutula, which is thought to be the garden escapees, has many medicinal uses (for example treatment of the upper respiratory tract infection). It has been identified in the province of Kütahya as an invasive plant. The record of this invasive plant is also a new genus record (Grindelia) for the flora of Turkey. Photographs and distinctive characters (such as papus awns, glandular hairs and leaf features) as well as plant descriptions are presented in the article. The differences of Grindelia hirsutula from genus Inula which is present in the flora of Turkey have been determined. Information about the isotype specimen of the plant in the Kew Herbarium and its distribution in the world are given. [ABSTRACT FROM AUTHOR]
