mutant clementines

Have we crossed a point where citrus growers no longer market actual clementines? After two boxes of the fruit, I can only guess that we are being sold another variety packed in clementine boxes. Or perhaps they've developed a hybrid variety. Either way, they're not as good as they've been in the past.

To wit, true clementines should have the following characteristics:

• Loose, bumpy rind that peels off easily
  
• Smallish, flat body
  
• No seeds
  
• Loose sections
  
• A sweet, almost-mandarin flavor

Instead, what has come out of the clementine boxes is:

• A rind more reminiscent of a navel or valencia orange
  
• Full, round body
  
• Occasional seeds
  
• Densely packed sections that have to be pulled apart
  
• The tart, orange-y flavor usually associated with common varieties

I've done a bit of internet research, but haven't turned up anything yet. Anyone know?
