Abstract (2. Language): 
In this study the pollen morphology of eleven Limonium Miller (Plumbaginaceae) species which are growing in inland saline habitats in Turkey has researched. Pollen grains are according to aperture type and number generally tricolpate, rarely dicolpate and/or tetracolpate. Also according to pollen shape, they are suboblate or oblate spheroidal. Colpi are long and wide, their limits are distinct. Terminals of colpi are sharp. Exine structure is semitectat and exine ornamentation is finely or coarsely reticulate-scabrate. Sexine is always thicker than nexine. Pollen grains, which belong to Limonium species, have shown variation on colpus type, shape and exine ornamentation. Examined Limonium species are seperated in three groups according to their palynological features and their pollen definitions have been done. Boxplot graphics of polar axis, equatorial axis and Amb measures have been drawn.
Abstract (Original Language): 
Bu çalışmada, Türkiye'nin iç kesimlerindeki tuzcul habitatlarda yayılış gösteren on bir Limonium Miller (Plumbaginaceae) türünün polen morfolojisi araştırılmıştır. Polenler apertür şekli ve sayısı bakımından genel olarak trikolpat, nadiren dikolpat ve/veya tetrakolpattır. Polen şekilleri bakımından ise, suboblat ya da oblat-sferoid'tir. Kolpuslar oldukça uzun ve geniş, sınırları belirgin, uçları sivridir. Ekzin yapısı semitektat, ornemantasyonu küçük ya da büyük retikülat-skabrattır. Sekzin, nekzinden her zaman daha kalındır. Limonium türlerine ait polenlerin kolpus sayısı, şekli ve ekzin ornemantasyonu bakımından değişiklik göstermektedir. İncelenen türler, palinolojik özelliklerine göre üç gruba ayrılmış ve türlere ait polenlerin tanımları yapılmıştır. Polenlerin polar eksen, ekvatoral eksen ve Amb çap uzunluk değerlerine ait kutu çizgi grafikleri çizilmiştir.
