Jason,  I got those two figs as "Brown Turkey" from two separate and reliable sources, James Robin and Joe Morle. I had never grown Brown Turkey until recently and when my first tree started producing, my reaction was pretty much like yours.

I don't know if these two figs are Celeste strains (hopefully DNA will answer that), but respected southern fig growers with lots of experience didn't think so.  It's  confusing - especially since Condit doesn't mention a smaller Brown Turkey.  He states that "The Brown Turkey ranks with Celeste (Malta) as the most popular dooryard fig from Texas east to Florida and north to Maryland."  But he also states that it's average weight is 28 grams and that it mostly is without a neck.  That is the description of English Brown Turkey, which is larger and blander than this fig.  This fig has a definite neck and is about half the size Condit described.

As for size and shape of the Monrovia BT and Sumadija, as you can see from the pictures there is variation.  I posted the pictures to show that precise point.  With any of my figs, I don't see uniform size - even on the same tree.

Fignut, yes my figs did vary in shape in terms of neck overall the body is always round but the neck did vary from short to longish like the pics you posted. Again the differences between the monrovia BT & Black Yugo or Sumadija Dusan is Minor in leaf shape & Fig shape size & Flavour. When my figs figs ripened I thought maybe san Piero then I seen pics of Joe Morles fig and thought ok maybe not then I seen the pic drawn by giorgio gallesio and again I was left scratching my head.

Fignut, thanks for correcting me.  I guess I should have read more closely.  But to add to the confusion, I was looking through the GRIN database today and found a San Pietro listed there.  So, Morle's fig can be a Pietro, or am I wrong again?  Here's the link...GRIN  DFIC 79

Also, here's a quote from Morle's web page on the origin of the name.

The name was given because the first crop ripens around St. Peter's Day, June 29, in the                 Central and Southern Mediterranean.

San Pietro is a white fig. Not to be confused with San Piero wich is Dark.

Nelson,  The figs in Gallesio's picture do look narrow.  But Jon's entry for California Brown Turkey look similar to these varieties. 

Hmmm well I have not gotten any breba yet on either one of these figs so far to see if its elongated. Now I need to get me an Abicou from Pierre Baud since its another syn. for san piero and see if its the same as these other two.
