Meyer separated Thlaspi into 12 genera, specifically using the seed-coat anatomy. Currently, only 4 species have been retained in Thlaspi s.str and all of the other species were divided into other genera, one of which was Thlaspiceras F.K.Mey.. Based on recent molecular studies and morphological features, Al-Shehbaz (2014) suggested recognizing all of Meyer's segregates under Noccaea and Thlaspi s.str. All of Meyer's Thlaspiceras species, namely Th. dolichocarpum (Zohary) F.K.Mey., Th. eigii (Zohary) K.Mey., crassifolium A.Huber-Morath andF.K.Mey.,Th. bovis F.K.Mey., Th. oxyceras (Boiss.) EK.Mey., Th. capricornutum F.K.Mey.,Th. huber-morathii F.K.Mey., Th. cappadocicum (Boiss. and Balansa) F.K.Mey., Th. triangulare F.K.Mey., Th. rechingeri F.K.Mey., and Th. elegans (Boissier) F.K.Mey., grow in Turkey or on the Syrian side of the border between Turkey and Syria. Meyer classified Thiaspiceras taxa under 3 sections: Dolichocarpa F.K.Mey., Thlaspiceras, and Acornuta F.K.Mey.. The current study makes use of the above mentioned species, except for Th. oxyceras, Th. capricornutum F.K.Mey., Th. dolichocarpum (Zohary) F.K.Mey., and Th. bovis F.K.Mey. The plant materials used in this research were collected in Turkey between 2014 and 2016. Specimens were identified according to Meyer's identification and named according to Meyer. A total of 12 inter-simple sequence repeat (ISSR) primers, with 52 reliable polymorphic bands, were used in the cluster analyses. The dendrogram obtained supported all of the previously proposed classifications. A detailed discussion regarding previous classifications of the group and the clusters revealed using the ISSR markers is also provided herein.
