Was quite surprised to see this plant in Crystal Cascades, which I presume is Abroma mollis. As with many other plants, this species was previously in the Sterculiaceae (Cacao family) but is now under the Malvaceae (Mallow family). I recognized the very distinctive fruit as I had previously seen a relative, Devils cotton (A. augusta) in the Singapore Botanic Gardens. I remember A. augusta to be a lot more robust and having palmate leaves. If I am not wrong, there are only two species of Abroma in the world. This was previously called Abroma fastuosum.
The plant was somewhat vine-like and had Begonia-like leaves, wiz, the leaves had heart-shaped bases. The stems were somewhat prickly. The flowers of this plant was a totally new concept for me. The blossoms were hanging downwards and the petals were hanging loosely. Around the base of the flower were some very intricate frilly-like structures. It reminded me somewhat of a strange passion fruit flower. When ripe the fruit appears to turn upwards. Very exquisite indeed.
