Abstract (2. Language): 
In the present study, morphology and comparative leaf anatomies of Euonymus latifolius subsp. latifolius, E. latifolius subsp. cauconis and E. leiophloeus, recently reported new record for the flora of Turkey are evaluated. In morphologically, two species resemble each other, but E. leiophloeus differs by longer and erect linear wings (10 -15 mm long), smaller capsules (4-5 mm long) and flowers (4-merous). For this examination, several Euonymus specimens were examined in morphologically and six Euonymus accessions from distinct populations are investigated in anatomically. Dorsiventral (=bifacial) type leaf, hypostomatic stomata (only exist on abaxial epidermis), and cyclocytic stomata cells are observed in all examined accessions here. Detailed measurements were performed in accessions. Populations differ in mainly the shape of midrib vascular bundle, accesssory bundles, and upper and lower epidermal cell shape in surface view.

Abstract (Original Language): 
Bu çalışmada; Euonymus latifolius subsp. latifolius, E. latifolius subsp. cauconis ve yakın zamanda Türkiye florası için yeni kayıt olarak rapor edilen E. leiophloeus taksonlarının morfolojileri ve karşılaştırmalı yaprak anatomileri değerlendirilmektedir. Morfolojik olarak, E. leiophloeus ve E. latifolius türleri birbirlerine benzese de; E. leiophloeus sahip olduğu uzun ve dik kanatları (10-15 mm uzunlukta), daha küçük kapsül meyveleri (4-5 mm uzunlukta) ve çiçekleri (4-parçalı) ile farklılık göstermektedir. Çalışma için 6 farklı lokaliteden Euonymus örnekleri morfolojik ve anatomik olarak incelenmiştir. İncelenen tüm örneklerde dorsiventral (bifasial) tip yaprak, hipostomatik stoma (yalnız alt yaprak yüzeyinde mevcut) ve siklositik stoma hücreleri gözlemlenmiştir. Örnekler üzerinde detaylı ölçümler gerçekleştirilmiştir. Populasyonlar başlıca orta damar iletim demetlerinin şekli, ilave demetler ile yüzeysel görünümde üst ve alt epidermal hücrelerinin şekli ile farklılık göstermektedir.
