In a recent post about lemon shape being affected by high temperatures

a grower sent an image of what I thought was  a blurred view of something that was circled.  I responded saying that I couldn't make it out, and a better image should be sent.

The grower resent the image, but this time it was about the long yellow thing in the background that was being asked about.  The tree is planted next to a chile pepper plant and the question was whether the shape was affected by the chile proximity.

The grower had never seen anything like it before and I haven't either.  But rack it up to the high temperature wave during flowering and the rapid fruit growth period and hormones gone amuck.  if temperature extremes become more common, unusual fruit shapes will likely become more common.
