Asteraceae familyasından yeni bir cins, Turanecio (Senecioneae oymağı)

Turanecio Hamzaoğlu, Asteraceae familyasının yeni bir cinsi olarak tanımlandı. Önceden Senecio L., Cineraria L. veya Iranecio B.Nord. cinsleri altında yer alan on tür, yeni cinse aktarıldı. Bu cins 4-loblu tüpsü çiçeklere sahip olduğu için Senecioninae altoymağının “Quadridentate Grubu” içinde yer alır. Yeni cins Dolichorrhiza (Pojark.) Galushko cinsine oldukça benzerdir, fakat rizomunun kalın, anter tabanının kısa-sagittat, sitilus dalları alt yüzeyinin papillat ve pappusunun kalıcı olmasıyla ondan farklıdır. Türkiye orijinli olan Turanecio Kafk asya, İran ve Irak’a kadar yayılış gösterir.

A new genus, Turanecio, of the Asteraceae (tribe Senecioneae)

Turanecio Hamzaoğlu, a new genus of the Asteraceae, is described. Ten species are included, previously referred to Senecio L., Cineraria L., or Iranecio B.Nord. This genus belongs to the "Quadridentate Group" of the subtribe Senecioninae, because of the 4-lobed disc florets. The new genus closely resembles Dolichorrhiza (Pojark.) Galushko, but differs by the thickish rhizome, the short-sagittate anther bases, the style branches with papillate lower surface, and in possessing a persistent pappus. Turanecio is centred in Turkey, with species in the Caucasus, Iran, and Iraq.
