Schefflera schizophylla 'Nova' (Heptapleurum schizophyllum)

An unusual leaf form of Schefflera, the fan shaped leaf is heavily lobed. Grows to about 10' in the ground, popular as a house plant as well, bright light, can take full sun in the tropics, but looks better in filtered light.

I have also seen it called 'Shevy Nova'.
