I have been looking at these lemon figs on ebay and I noticed they go by a couple of different alias  Italian Honey - White Marseilles - Blanche- Lattarula - Heritage could someone please clear up this for me? Is a lemon fig the other name stated or are they just related? 

So have I and from what read my understanding is ... It is an Italian honey fig, when it ripens it turns yellowish with a hint of green, supposedly some say the fruit (when you bite into it) has a subtle lemon undertone. Sounds really good!

They may be the same, they may be related, they may not be the same or they may not be related. On Ebay they may be most anything, and may not be anything like what is pictured since 90% of the pix used on Ebay to see fig trees and cuttings are pirated and not even pictured of what they are selling.

Welcome to the "fun" that is fig names.
