Woody Fruit and Other Avocado Abnormalities
Keeping your eyes open in the field can result in some unusual finds. A recent observation that was sent in concerned an avocado fruit which didn't really have the shape of an avocado and certainly not the texture. It is a "woody avocado" as described by Professor Robert Hodgson of UCLA in 1935:

Dr. Art Schroeder at the same institution pursued it further, still with no clear cause for the condition:

Mary Lu Arpaia and Reuben Hofshi revisited the issue of avocado fruit abnormalities in 2002:

It is still not clear what causes this condition, other than it is not transmissible and does not occur very often.
