ERYTHROCHITON BRASILIENSIS

From the Family Rutaceae which includes plants such as the Lime plant, I am not familiar with this monopodial-looking plant at all. In fact, it reminds me of a plant that I learnt not long ago - the Archidendron.

RAVENIA SPECTABILIS

From the Rutaceae Family, this hardy, pest free plant is known by the synonym Lemonia spectabilis and the common names Limonia and Ravenia Pink.

If this plant is interesting, the variegated one is simply amazing. 2 links are shown below:
