wanna,
as mentioned, platycerium coronarium in singapore.
it can be seen easily on some of the road.
i think that most of them are planted by the national park of singapore except a few that were naturally grow in some of the forrest.
p. coronarium also known as crown staghorn due to the shape of the shield fronds.
& if you pay attention, even those that i have seen at the "forrest", the fertile fronds are narrow & there isnt any "hair" on the shield & fertile fronds.
this one is growing outside my friend house. take a look at the left, the shield fronds are turning brown, that is because it is facing hot afternoon sun.

Platycerium Ridleyi was discovered by Sir Henry Nicholas Ridley in Singapore at bukit timah forrest. He was the botanist & director of Singapore botanic garden.
We used to have many P. ridleyi in Singapore till lots of trees were chopped off & the forrest were used to build public apartments & houses.
Due to its fertile fronds which are erect like the deer's antler, it is commonly know as deer horn.
Few years back, I still see some of them in Singapore. Will get back to you when i see them as i am not too sure if they are still there or have turn into compost completely & extinct completely in Singapore......... what a shame.

Platycerium willinkii, relative of p. bifurcatum, I believe that they are mounted on the trees by the national park of Singapore. Will post here when I go take the shots.
