Dipteris conjugata

This horticulturally interesting fern is found in many places in East Asia, mostly in lower montane areas but has also been recorded in coastal areas in the lowlands, including Singapore. Botanists believe it is a very primitive fern - maybe even a living fossil, so one can imagine a vegetarian dinosaur munching on it during the Mesosiac period.

I found stands of this plant growing on open slopes in Fraser's Hill. These plants need open space with much light in order to thrive. Their demise in some parts of Singapore had been attibuted to crowding out by exotic weeds.
The palm-shaped fronds are large - about 50cm across ....

....and the venations give it a very interesting texture but so far I have not seen it in the horticulture trade. Is there anyone out there growing this ?

The plants are very difficult to establish unless you grow from spores.

I find it hard to believe that there is a lowland population in singapore... probably a different species?

then again, i still populations of these growing at 2000m on titiwangsa mountain range.. in very dim and misty surroundings.

Kevin - if you do a google you can find a paper by Alvin on plight of this sp in Singapore.

Hon E - so you had success with spores ?

Have not grown from spores yet...but my plantlets from Ledang did not make it.
