Abstract

Some interesting Bupleurum (Apiaceae) specimens with very branched stems, (1–)2-rayed inflorescences and ivory-white bracteoles were collected from Tepebaşı District (Eskişehir Province). The specimes, at first glance, resembled the Bupleurum pendikum (sect. Aristata) species, which is endemic in Türkiye, as a habit. However, as a result of detailed examination, it was determined that there were some differences. Based on these differences, the specimens were presented to the scientific world as a new variety and were named Bupleurum pendikum var. eskisehiricum. The fact that the inflorescences are (1–)2 rays (not (2–)34(–5)); the bracteoles are 2.6–3.7 mm broad, ovate-elliptic and with arista up to 0.5 mm long (not 1.2–2 mm broad, lanceolate and with arista 11.5 mm long); the petals 0.6–0.8 mm broad (not 0.4–0.5 mm broad); the filaments 0.7–0.8 mm long (not c. 0.5 mm long) and the mericarps 2.7–3.1 × 1.1–1.3 mm (not 2.2–2.4 × 0.9–1 mm) are the most obvious attributes that separate Bupleurum pendikum var. eskisehiricum from B. pendikum (var. pendikum), that is a close taxon. Here, a detailed description of the new variety, informative photographs, and some ecological preferences were given.

Here, the specimens presented as a new species were collected during the “Biorestoration Observation Studies” realized within the scope of the Trans-Anatolian Natural Gas Pipeline Project (TANAP). I would like to express my gratitude to the TANAP Natural Gas Transmission Company and the contractor Assystem (Türkiye), for preparing the foundation for this study and for providing contributions to the Bupleurum taxonomy.

Türkiye’den yeni bir Bupleurum (Apiaceae) varyetesi

Abstract

Tepebaşı ilçesinden (Eskişehir) çok dallanmış gövdeli, (1–)2-ışınlı çiçek durumlu ve fildişi-beyazı bırakteollü olan bazı ilginç Bupleurum (Apiaceae) örnekleri toplandı. Örnekler ilk bakışta habit olarak Türkiye’de endemik olan Bupleurum pendikum (sect. Aristata) türüne benzetildi. Fakat yapılan detaylı inceleme sonucunda bazı farklar olduğu tespit edildi. Bu farklılıklara dayanarak, örnekler bilim dünyası için yeni bir varyete olarak tanıtıldı ve Bupleurum pendikum var. eskisehiricum olarak adlandırıldı. Çiçek durumu ışınlarının (1–)2 adet olması ((2–)34(–5) değil); bırakteollerinin 2.6–3.7 mm eninde, yumurtamsı-eliptik ve en fazla 0.5 mm uzunluğunda kılçıklı olması (1.2–2 mm eninde, mızraksı ve 1–1.5 mm kılçıklı değil); petallerinin 0.6–0.8 mm eninde olması (0.4–0.5 mm eninde değil); filamentlerinin 0.7–0.8 mm uzunluğunda olması (c. 0.5 mm değil) ve merikarpının 2.7–3.1 × 1.1–1.3 mm olması (2.2–2.4 × 0.9–1 mm değil) Bupleurum pendikum var. eskisehiricum’u yakın takson olan B. pendikum (var. pendikum)’dan ayıran en belirgin özelliklerdir. Burada; yeni varyetenin detaylı betimlemesi, bilgilendirici fotoğrafları ve bazı ekolojik tercihleri verilmiştir.
