Anthurium andraeanum album (I think, please correct me if I'm wrong)
Some from the ginger family...
Anyone know what is this one?
Costus productus
Etlingera elatior
The following two, I have no idea... can someone help?
Think the last one is a variant of Turnera ulmifolia, as it does look very much like Turnera ulmifolia Elegans).
