Abstract

Some interesting Festuca (Poaceae) specimens with intravaginal and extravaginal vegetative shoots were collected from Ayaş District (Ankara Province, Türkiye). As a result of comprehensive review, it was determined that the specimens were similar F. sclerophylla known from Russia, Iran, and Türkiye, but different from this. Taking into account the differences detected, the specimens were presented to the scientific world as a new species and was named Festuca ankarica. The fact that the culms with extravaginal and intravaginal shoots (not with only extravaginal shoots), leaf sheaths closed to mount and glabrous (not open to mount and scabrous), ligule 5-7 mm long (not 2-4 mm long), leaf blade 12-22 cm long (not 45-60 cm long), upper glumes 1.8-2.2 mm wide (not 2.5-3 mm wide), lemma 1.3-1.8 mm wide (not 3-3.5 mm wide), anthers 5-6 mm long (not 4-4.5 mm long) are the most apparent attributes that separate Festuca ankarica from F. sclerophylla, that are a close taxon. Here is a detailed description of the new species, with illustrative photographs and some general ecological preferences.

Festuca ankarica (Poaceae), Ankara (Türkiye)’dan yeni bir tür

Abstract

Ayaş’tan (Ankara, Türkiye) intravajinal ve ekstravajinal vejetatif sürgünleri olan bazı ilginç Festuca (Poaceae) örnekleri toplandı. Kapsamlı inceleme sonucunda, örneklerin Rusya, İran ve Türkiye’den bilinen F. sclerophylla’ya benzediği, ancak ondan farklı olduğu tespit edildi. Tespit edilen farklılıklar dikkate alınarak, örnekler bilim dünyası için yeni bir tür olarak sunuldu ve Festuca ankarica olarak adlandırıldı. Gövdelerin intravajinal ve ekstravajinal sürgünlü (sadece ekstravajinal sürgünlü değil), yaprak kınlarının ağza doğru kapalı ve tüysüz (ağza doğru açık ve pürüzlü değil), ligulanın 5-7 mm uzunluğunda (2-4 mm değil), yaprak ayasının 12-22 cm uzunluğunda (45-60 cm değil), üst glumaların 1,8-2,2 mm genişliğinde (2,5-3 mm değil), lemmanın 1,3-1,8 mm genişliğinde (3-3,5 mm değil), anterlerin 5-6 mm uzunluğunda (4-4,5 mm değil) olması, Festuca ankarica'yı yakın takson olan F. sclerophylla'dan ayıran en belirgin özelliklerdir. Burada, yeni türün ayrıntılı bir tanımı, tanıtıcı fotoğrafları ve birkaç genel ekolojik tercihi verilmiştir.
