Abstract

Tomarza’dan (Kayseri, Türkiye) küçük korollaları ve belirgin dört sıralı başakları ile dikkat çeken bazı ilginç Crucianella (Rubiaceae) örnekleri toplandı. Crucianella seksiyonuna ait C. disticha ve C. macrostachya türlerine benzeyen bu örnekler; düğümlerinde 4(-5) yaprak bulunması, başaklarının belirgin dört sıralı olması, bıraktelerinin eliptik-mızraksı olması, korollalarının 2,6-3,8 mm boyunda ve koralla tüplerinin boğumsuz olmasıyla farklıdır. Bu farklılıklar ilgili literatür ışığında değerlendirildi ve örneklerin bilim dünyası için yeni bir tür olduğuna karar verildi. Crucianella turcica olarak adlandırılan yeni tür, tip adresinde 1520-1600 metreler arasındaki taşlı bozkırlarda yetişir. Bu çalışmada yeni türün detaylı betimlemesi, benzerlik gösterdiği C. disticha ve C. macrostachya ile morfolojik karşılaştırması, türe ait bilgilendirici fotoğraflar ve bazı ekolojik tercihler verilmiştir. Ayrıca mevcut ve muhtemel yayılışı ile tespit edilen tehditler dikkate alınarak, tür için IUCN tehdit kategorisi önerilmiştir.

Crucianella turcica (sect. Crucianella, Rubiaceae), A New Species from Turkey

Abstract

Some interesting Crucianella (Rubiaceae) specimens were collected from Tomarza, Kayseri, Turkey, which drew attention with small corollas and distinctly tetrastichous spikes. These specimens, which are like C. disticha and C. macrostachya, belonging to the Crucianella section, are different since they have 4(-5) leaves on their nodes, that they have distinctly tetrastichous spikes, that their bracteoles are elliptic-lanceolate, that the corollas are 2.6-3.8 mm long, and that there are corolla tubes not nodes. These differences were evaluated according to the related literature and it was decided that these specimens are a new species for the world of science. The type address of the new species, which is named Crucianella turcica, is grown in the stony, sparsely vegetated plains at an elevation of between 1520-1600 meters. In this study, the detailed description of the new species, the morphological comparison of the species with C. disticha and C. macrostachya, informative photographs for the species and some ecological preferences were given. Furthermore, by taking into consideration the threats, which were determined with the existing and probable distribution, the threat category of the International Union for Conservation of Nature (IUCN) was proposed for the species.
