I took the photos of these semi-aquatic or emergent plants on 1 Oct.The 1st 3 photos were of the Victoria amazonica that I posted recently.
The 4th photo was of a beautiful variegated plant that was labeled Seledri although I have my doubts.
The last few photos were of this unknown plant with amazingly yellow leaf-liked flowers and reddish leaves. The plant could likely be one of the Ludwigias.
NB on 30 Nov 10: I forgot to update that the unknown Seledri is actually the Oenanthe japonica 'Flamingo' (common name: Variegated Water Celery, Japanese Parsley).
