Cycad IDs (With Working Photos)

[ahosey01]

ID suggestions please.  I have my thoughts and I think I'm right, but as a non-pro in the cycad world, want someone else to confirm for me:

Cycad 1:

 

Cycad 2:

 

 

Cycad 3:

 

Hope that was  better @Tracy.  @PALM MOD can you delete the other thread with the bad images?  Thanks!

This one is most definitely Encephalartos genus, and looks like princeps to me on initial look.  A closer examination of the abaxial and adaxial leaflets and a caudex photo would rule out the other species, that I would consider which would be Encephalartos nubimontanus or something similar in that family, or even Encephalartos lehmanii.

Encephalartos princeps has different colors abaxial and adaxial (more blue on the upper or adaxial side of leaflets).  Meanwhile, Encephalartos nubimontanus as with the other Eugene complex species, will have the same colors on both sides of the leaflets.  Encephalartos lehmannii doesn;t have the insertion angles on the leaflets as compared to E princeps, which a closer photo of the leaves would identify, and the collars at the bases of the leaves are an orange color on E lehmannii vs a dull yellow on E princeps.

Dioon spinulosum probably, but definitely a Dioon.

Looks like a Ceratozamia to me, but without more detail I wouldn't guess on species.  Even some of the plants in this genus that I own have been reclassified since I acquired them, so my id's are incorrect.  I'm sure someone like Gallop, who has many Ceratozamias, can provide some species options for you.

@Gallop

Thanks @Tracy.  I nailed the Dioon (was thinking edule but I'll see the leaves closer and decide) and I figured the blue one was Encephalartos but had no idea on the species.  The Ceratozamia one I got completely incorrect, lol

@ahosey01 I think the Dioon is probably one of the long-leaf versions of Edule.  The leaflets are too thin to be Spinulosum or Rzedowskii, and maybe too thin to be Mejiae.  I have an Edule in the front yard that has very long (3-4 feet) fronds, so if grown in shade they could be a bit longer.  There are a bunch of narrow leaflet ones that I don't know how to identify, like Purpusii, Argenteum (somewhat obvious), Sonorense (now Vovidesii?), and a few recently named species.  One thing I can say for sure is that's an old plant.  Based on the trunk size I'd think somewhere in the 50-100 year range?

The first one I'd guess Encephalartos Villosus.  I can't tell if the leaves have thorns in the photo though.  Some are prickly, some are mostly smooth leaves: https://www.junglemusic.net/Encephalartos_Species/Encephalartos_villosus.html

and https://www.agaveville.org/viewtopic.php?t=985

If they are totally smooth I'd also guess some kind of big Ceratozamia.

Merlyn is probably correct on the first id as Encephalartos villosus.   A closeup photo of the caudex would confirm the id, since Encephalartos caudices appear quite different than Ceratozamia.   If it is an Encephalartos,  villosus is the only species with leaflets like that.  

Closeup photos of leaflets and caudices are always very helpful in identifying a Cycad species, as well as cone photos if they are present.

I have this basic C.revoluta. It finally is starting to flush. Are these normally this late?

Cycads are in their own schedule. They do typically push in the Spring and Fall. Some once a year, some twice a year, some skip a year or two. There’s no telling. Once they get comfortable their specific schedules seem pretty consistent though.
