Oncosperma fasciculatum in habitat


doranakandawatta

Recommended Posts

Around Badulla, we found the endemic Oncosperma in Sri Lanka growing in the mountains,

It was quite exhausting to reach them, as it must be for any species one want to see in habitat.

Seeing the leaves from close, I understood why O. fasciculatum is NOT O. tiggiliarum or O. filamentosum.

Fantastic, Philippe! Such a fine array of photos, and you went to some difficulty to get them. Thank you! Would you mind commenting further on the differences you observed between species?

Hey, Philippe, excellent!!!

That's what one calls a really good contribution! Never saw so many photos of Oncosperma fasciculatum all together, and in habitat on top of that! Plus, many different angles and details!!!

Congratulations for the effort!

Meilleurs voeux pour 2014!

The difficult hike looks like it was worth every ache and pain, thanks for the photos! I haven't done any homework on these, so are they solitary or clumping? The pinnae don't look anywhere near as pendulous as O. tigilliarium. Thanks Philippe.

Tim,

They are clumping,

As you can see on the pics they grow in a ravine where the soil is rich with humus as next to the ravine (where I climb on the picture) , the soil is poor, no organic material. Because of human practice or not, I can't tell...

KIm,

O. fasciculatum is the endemic Oncosperma in Sri Lanka, it has shorter leaves and leaflets are put together in a caracteristic way. It seems the are not so tall.

It's different with O. filamentosum as it is tagged in Peradeniya (O. tigilliarum) , the more than 100 years old palm I love but I am afraid it'll disappear soon.
