    The Brassicaceae (Cruciferae) is one of the largest Angiosperm families, comprising approximately 340 genera and more than 3350 species, distributed throughout the world, chiefly in temperate regions of the Northern Hemisphere. According to the gridding system used for the flora of Turkey in May 2013 from Bornmuellera cappadocica B9 square corresponding to Van Gurpinar area, and in June 2014 Physocardamum davisii B9 square corresponding to the Agri Tutak area. The collected specimens were pressed at the field using the herbarium rules, the locations and the population observations were carefully recorded, and macro and general photographs that would reflect the natural form of the plants in the best possible way were taken. The pollen characteristics of the species were studied in preparations that followed the Non-asetholize Method (Wodehouse Method) for light microscopy (LM) studies. Measurement for the Polar axis (P) equatorial ax is (E), colpi length, apocolpium, mesocolpium, exine thickness and intine thickness were made for each sample by light microscope. The pollen and seed morphologies were studied for the first time using a Scanning Electron Microscope and a Light Microscope. The pollen in the SEM made-ups as a result of exine surface and surface ornamentation on the measurements by light microscopy morphometric measurements of the seeds LM and SEM microphotographs taken, the size was measured and surface ornamentation will be identified.Original Abstract: Brassicaceae (Cruciferae) basta Kuzey Yarimkure'de iliman bolgelerinde olmak uzere dunya capinda yayilan yaklasik 340 cins ve 3350 den fazla turun olusturdugu, en buyuk kapali tohumlu ailelerin biridir. Turkiye Florasi'nda kullanilan kareleme sistemine gore Mayis 2013'de Bornmuellera cappadocica turu B9 karesinde bulunan Van ili Gurpinar ilcesinden, Haziran 2014'de Physocardamum davisii turu B9 karesinde bulunan Agri Tutak ilcesinden toplanmistir. Toplanan ornekler arazide herbaryum kurallarina uygun olarak preslenmis, lokalite bilgileri ve populasyon gozlemleri dikkatlice kayit altina alinmis ve bitkilerin dogal halini en iyi sekilde yansitabilecek makro ve genel fotograflar cekilmistir. Turlerin polen ozellikleri isik mikroskobu (IM) calismalari icin Asetoliz olmayan (Wodehouse Metodu) Yontemi kullanildi. Isik mikoskobu ile herbir ornegin Polar eksen (P), ekvatoryal eksen (E), kolpus uzunlugu, apokolpium, mezokolpium, ekzin kalinligi ve intin kalinligi olculdu. Polen ve tohum morfolojileri Tarama Elektron Mikroskop ve Isik Mikroskobu kullanilarak ilk kez calisildi. Polenlerin SEM'de yapilan cekimler sonucunda ekzin yuzeyi ve yuzeyindeki suslemeler uzerinde olcumler, Isik mikroskobu ile morfometrik olcumleri tohumlarin IM ve SEM mikrofotografileri cekilmis, boyutlari olculmus ve yuzey suslemeleri tespit edildi.
