Unknown Macrozamia

[Geoff]

Sorry I did not take any other photos of this nice plant I saw today at a palm meeting in Whittier... very blue leaves and so upright... what is it? Went through the typical blue Macrozamias and none seem to fit that well... labeled as Macrozamia johnsonii.

[Trava]

Maybe this one?

May be Macrozamia macdonnellii

[Geoff]

people who seemed to know cycads did not feel dyeri or fraseri were likely possibilities (though I had guessed dyeri myself). mcdonaldiana is definitely not a likely possibility.

[BS Man about Palms]

Geoff, I had forgot I own a mcdonnelli x johnsonii I wonder if its a hybrid?

[Walter John]

Macrozamia glaucophylla ?

[Geoff]

Well, A hybrid is certainly a possibility ... but no way to know for sure I guess for some years ahead.

Nice eye bill,

Loran whitelock made some of these several years ago and a few are floating around, its very possible that it is one of those plants. Mcdonnellii X Johnsonii

[DippyD]

I also know there ain't going to be enough room for that thoursii, whitelockii and the macrozamia cross in that little area

[DippyD]

Or whatever the other cycad is to the left maybe a cerat of some type

Those Cycads may look nice planted as they are now close together but wait a while and they will be jammed up one against the other and difficult to remove and transplant. I hope the owner is aware of that.

Very hard to tell, but I will say that in the Macrozamia reidlii and fraserii growing regions you'll see a few blue cycads growing some green, some with twisted up leaflets and some with regular flat leaflets. Some upright some more pendulous. These would likely have come from the same parent plant too. Macrozamia is such a variable genus.
