Sansevieria trifasciatat var. laurentii: Snake ...

[Cecil Lee]

This plant is quite common in Singapore, but always never placed directly at the frontage of the main entrance door. As each of the leave is pointed much like an Anglo Saxon knife blade.

This plant comes from Zaire.

It's family name is: Dracaenaceae. And it is commonly called: Variegated Snake Plant.

This plant has a cousin, which is much harder to find in Singapore. The profile of it's leave are the same except that it's yellowish and greenish band of stripes is horizontal vs the vertical stripes found on the attached Snake plant.
Worse still, this cousin is also called Snake plant but it has another tongue in cheek name: Mother-in-law Tongue. Another name is Bowsring.
