Ponapea as a Genus?

Recommended Posts

I have what I thought was a Ptychosperma ledermanniana. I went to bed last night and woke up to Ponapea ledermanniana. When did this happen?

Is anyone else growing this palm? Any luck? Appears difficult to grow from my perspective...certainly not as easy as the more common Ptychosperma species.

It was actually changed back to Ponapea ledermanniana a short while ago, in an article of the Linnean Society journal. The species was lumped in with Ptychosperma years ago, after it was named as Ponapea back in 1924. It is back where many feel it belongs. There are plants of P. ledermanniana around, and from what I have seen they grow quite simular to Ptychosperma species. They might enjoy a bit more shade for a while longer though, and need regulated moisture. I can not see them enjoying a drought much.

Nice palm, and a perfectly lighted photo as well.

When I first saw the topic I thought it read:

I assume more shade as a juvenile...then more sun as an adult??

Rick,

I would think that if you can grow Ptychospermas, then you can grow Ponapea. Likes partial shade (but I have a few that are very exposed) and humidity. Here's a group of 3 in a shaded location.

Rick,

Bo-Göran is correct, they are so simular they were in the same genus for 70 some years. So growing conditions should be kept the same. Most if not all Ponapea / Ptychosperma species in S. Florida should be in some form of shade when young, lessening as the plant grows larger. They might not die in full sun, but will not look as good.

Ponapea hosinoi looks fine at the Palmetum in Tenerife. In the past years it survived weeks of drought shaded just by a 5 m tall Schefflera actinophylla with no mulching. Survived various attacks of whiteflies.

I should have mentioned that the 3 in my photo above are P. ledermanniana.

And here's an up-to-date photo, taken minutes ago. (The one above was taken in Aug 2006).

Like Hemithrinax, Ponapea was at one time a recognized genus.  Both names have since been resuscitated.  It seems we are reverting back to old times.
