This Menispermaceae was
described by William Grant Craib in 1922. It's from Thailand, where it grows in peat
with some water and not too much sun. The flowers are, as seen on the
photo, very small and yellow. The caudex can grow to ten
centimetres in diameter, the vines reach for 50 centimetres or more.
It will grow half a meter and set flowers. Then the leaf will come. I
cut it back one year, and exactly the same happened once again!
