recently i received an assignment from my lecturer
i have to find information on two types or plant which are

alternanthera amoena
clerodrendrum macrosiphon

i have some problems to these plants

1st about the alternanthera amoena
i found out that alternanthera amoena also known as alternanthera ficoidea var. amoena, but when i googled it, there are a lot of different pictures, some are purple some are green some with different shapes...so which is the real one?
besides, the common name for this plant is "Joseph's Coat" or "parrot leaf"

2nd about the clerodrendrum macrosiphon
i know that this plant is also called as "witches tongue", "do-re-mi" plant, "musical note" plant and "morning kiss"...but i still do not have enough information..anyone can provide any useful information??

Thanks for anyone that help
