Corchorus fascicularis is first reported for Thailand. Triumfetta repens is not currently reported from Thailand anymore, although
given the overall distribution of this species it may have been overlooked. Lectotypifications of Colona elobata, Columbia flagrocarpa
var. siamensis, C. winitii, Corchorus siamensis, Grewia lacei and G. winitii are proposed here. Triumfetta rhomboidea is the correct
name for T. bartramia
