Green Cycad I.D. needed

Recommended Posts

Randy, yatchingone, was very generous in gifting this beautiful cycad to me a couple of years ago. He said it was an unknown, maybe a hybrid. So I put it out in full, all day sun, with minimal water and it's doing very well despite the harsh conditions it sees. It's at least doubled in caudex size. When it was younger I had people say it was E. kisambo, E. turneri, but other have since said no way on those. Recently someone suggested E. altensteinii. I don't know enough about cycads to even guess. Got any ideas?

I do some experiments and learning in my garden with palms so you don't have to experience the pain! Look at my old threads to find various observations and tips!

Ok Matt I short changed you! Encephalartos pauldentoneyeburnerensis!!!:rolleyes:

Your nieghbor Bob has very large E. altensteinii. The pics are of my Bushman river form of altensteinii that is 6' tall over all. The pups are imature leaf form. Also notice in the elongated pic the underside of the leaf is a different color than the top of the leaf. That cycad is growing quite well for you! :greenthumb:

I believe it is E. natalensis high land flats form

The prickles at the termination of the petiole eliminate E. altersteinii

Heres a a form --- I admit tho that I don t have the keen eye of a splitter ....

Best rgards

ed is right about the prickles eliminating altensteinii....if you look closely at the altensteinii in randy's pic, you will see that where the petiole meets the caudex it is prickle free...

Well it is definitely an Encephalartos! I'm not an expert but I'm going to wager a bet that it's a natalensis.

So Matt, what does this look like today?  Did you ever reach a decision on species.  I imagine its pretty large after 7 years of growth.  Leaflets didn't look cupped enough to me to be Encephalartos turneri, and turneri usually loads up leaves giving it an almost plumose look as seen below.
