Abstract

Smilax asiatica Kladwong, Chantar. & D.A.Simpson and S. goeringii Kladwong, Chantar. & D.A.Simpson are proposed as new names for two later homonyms, S. laevis A.DC. and S. japonica (Kunth) P.Li & C.X.Fu, respectively. Two taxa are reduced to synonymy: S. petiolatumidus B.R.Moore, Narkkong, Th.Moore & Lutat is placed into the synonymy of Dioscorea cirrhosa Lour. and S. zeylanica var. penangensis A.DC. is a new synonym of S. asiatica. Smilax ferox Wall. ex Kunth and S. polyacantha Wall. ex Kunth are newly recorded for Thailand. Smilax asiatica, S. ferox, S. lanceifolia var. opaca A.DC., S. polyacantha and S. zeylanica var. penangensis are lectotypified.
