Sporobolus turcicus (sect. Crypsis, Poaceae), a new species from Türkiye

Öz

Some interesting Sporobolus (Poaceae) specimens were collected from Eskil, Aksaray, that have narrow inflorescence, long lower glume and caryopsis. In the careful examination made, the specimens resemble Sporobolus schoenoides and S. borszczowii belonging to the section Crypsis (subsect. Crypsis), but it was determined that it is different from them due to especially some generative characters. These specimens after compared with the closest taxa, it was decided that, it is a new species for science world and was named Sporobolus turcicus. Specimens of the new species grows at altitudes between about 910-920 meters in the dried salt marsh. The size and shape of some organs such as leaf blades (0.6-1.2 mm broad, puberulent to long-pilose inner surface, glabrous outer surface), lower glume (3.2-4.1 mm long), lemma (awn 0.6-0.8 mm long) and caryopsis (ellipsoid, 1.5-2.1 mm long), allow to recognize Sporobolus turcicus from its closest taxa. Here, the description of the new species, comparison with the similar taxa, informative photographs, and some ecological preferences have been given.

Sporobolus turcicus ((sect. Crypsis, Poaceae), Türkiye’den yeni bir tür

Öz

Aksaray, Eskil’den çiçek durumu dar, alt gluması ve karyopsisi uzun bazı ilginç Sporobolus (Poaceae) örnekleri toplandı. Yapılan detaylı inceleme sonucunda örneklerin Crypsis seksiyonuna (alt seksiyon Crypsis) ait Sporobolus schoenoides ve S. borszczowii'ye benzediği, ancak özellikle bazı generatif karakterler nedeniyle farklı olduğu belirlendi. Bu örneklerin yakın taksonlarla karşılaştırılması sonucunda bilim dünyası için yeni bir tür olduğuna karar verildi ve Sporobolus turcicus olarak adlandırıldı. Yeni türün örnekleri kurumuş tuzlu bataklıkta yaklaşık 910-920 metre rakımlarda yetişir. Yaprak ayaları (0,6-1,2 mm genişliğinde, iç yüzey havlı-uzun tüylü, dış yüzey tüysüz), alt gluma (3,2-4,1 mm uzunluğunda), lemma (kılçık 0,6-0,8 mm uzunluğunda) ve karyopsis (elipsoid, 1,5-2,1 mm uzunluğunda) gibi bazı organların boyutu ve şekli, Sporobolus turcicus'un en yakın taksonlardan ayrılmasını sağlar. Burada yeni türün tanımı, benzer taksonlarla karşılaştırılması, bilgilendirici fotoğrafları ve bazı ekolojik tercihlerine yer verilmiştir.
