Calling Palebotanists!

[I_gotta_rock]

Ya know, I'm great at plant identification if it's currently growing in my region. Dive back to the Paleozoic and I can tell Calamites from Cordaites, but that's about my limit without a book in hand. So far, I've had 8 and I still don't know what this is! I'm pondering the frond-like object running diagonally across the center of the picture. It looks like a fruiting body from Cordaites, but it lacks the sporophyll. It also resembles Corynepteris angustissima, but the only illustration I can find lacks sufficient detail.

 

This came from a mid-late Pennsylvanian Lewellyn Formation exposure in Columbia County, PA. It's about 4 inches (10cm) long.

Calamostachys would worth consideration. 

Oh, for a paleobotanist try @paleoflor .

Calamostachys  was my first impression. 

 

Look at 3a on this figure from George's Basement.

Ya know, that was one of the eight! I just missed that little illustration.  I found vols 1-3 on Archive.org yesterday. I think we have a match! Thanks, both of you!

@Rockwood and @Fossildude19, What makes you say Calamostachys specifically? This page shows a sister taxon. Got any more recent references, by any chance? Maybe one from the last century?

It just looks like one to me.  

 

You can have a look through this PDF.

Ah! That's really helpful, thanks!

Got any more Paleozoic plant stuff?

There are so many different time periods and environments represented within 3 hours of my home that I just can't settle on one type of life form.

Sometimes it just takes the right keyword!

I prefer a quaint old relic called a book.

Me, too!

 I have a section of my personal library for Miocene marine fossils, one for Cretaceous marine fossils, and one for the Devonian deposits, plus a couple plant books I was able to find recently. However, the books I have are not adequate to the current task and the more thorough ones are out of print. I am seeking info wherever I can. I will admit to spending $75 to get a .pdf printed at the copy shop (it was a VERY big book!) so I could flip through the thing rather than scroll back and forth endlessly. It seems that there is a general lack of books for paleobotany, though - physical or otherwise .
