In Malaysia, it is known with two names:
i- Lidah Mertua (direct translation: Mother-In-Law Tounge)
ii- Kelumpang Telur (Kelumpang = sorry, i don't know what is the translation for Kelumpang. Telur = egg)
Old folk in Malaysia always decorate the plant with eggshell, as u can see at below picture. The reason they stick eggshell on top of that plant, is because it is sharp and they don't want kids to accidentally cut themself.
