CYCAD (CYCAS) ID

[Ventri]

An acquaintance sent me this picture. Anyone have any Idea what it may be? All I can discern is that it's a non-sago palm cycas.

It seems to be going haywire on pup production.

I'd say a good chance it is Cycas Thouarsii.  They tend to pup a lot out of the side of the trunk.  There were a lot imported to the US (especially Florida) about 30-40 years ago.  That one is probably one from that batch.  They are commonly called "Queen Sago," though apparently the "official" Queen Sago is Cycas Circinalis.  There are 4 Cycas that are all very similar in appearance:

• Circinalis 80-90 degree on rachis w/long tapering tip, raised rib above visible but flat below.
• Thouarsii 45-60 degrees with more rounded tip, shiny big grooved midrib top, pale w/ raised rib underside, bluish haze on new flush.
• Rumphii 90 deg leaves glossy green w/flat midrib above, very pale w/raised midrib below.
• Seemannii deep green 45-70 degrees midrib flat above and raised below.

I don't think it's seemannii, the leaves seem to be more of a lighter lime color. The petiole on Rumphii doesn't seem too reminiscent, but that may be a bit variable.
It might be a Thouarsii... 

Here is a picture of the offsets.
