A question popped into my mind when I noticed what I believe is a male inflorescence emerging from a Ravenea glauca. In that this species is dioecious, I wondered if hybridization with other species within the genus is very common when species are grown in close proximity. I was trying to think if there were desirable characteristics that one might want to pull from two different Ravenea species in a hybrid. Anyone seen examples of hybrid Raveneas or experimented with them?

What is your palm with the thinnest stems? My record holder is a 15 year old Rhapis micrantha. The 1st stem (grown directly from seed, no offshoot) has a diameter of 4.6 mm, much less than the stem of a 3½ year old Chamaedorea tuerckheimii with 5.0 mm. (An old no more existent Rhapis subtilis had 4.7 mm.)
I guess good other candidates were Chamaedorea stolonifera and some Calamus spp.
I was checking my pots of palm seedlings this morning and I found this albino seedling in my pot of Cham klotzschianas. Albino seedlings are, unfortunately for the plants affected, not as rare as you might think. Albinism in palms occurs because a genetic defect in the seed produces a palm that is unable to manufacture chlorophyll. Lack of chlorophyll in green plants means the defective plant is unable to photosynthesize and feed itself. Right now this little guy is living off food storage in its seed. When that is used up the seedling will wither and die. After taking the following photos I put the pot of seedlings back under canopy and will let the albino one get the most out of its spark of life. Guess I'm a softie.

The Palm Society of Southern California will be having an article about hybrid palms in its magazine soon, and one of our contributors cited Merrill Wilcox's seminal article "How to make a hybird."
Anyone know where I can find it?
These are lovely little understory palms that deserve wider renown. They are surprisingly cold hardy: down to 28F. Current thinking lumps what were two species, C. geoniformis and C. tenella into just C. geoniformis even though these palms are distinctly different to uneducated eyes, including mine. I have two C. geoniformis vs. seven C. tenella. The geoniformis are much larger all around. C. tenella is almost impossibly dainty, sporting 3-4" leaves atop tiny stems thinner than a pencil
I just finished fall maintence on these little guys then took the following photos. These palms are well worth growing
