the latest issue of "Fruit Gardener" magazine (July/August 1999,
vol. 31, #4) has a color photo on the cover of a miniature durian - it
fits in the palm of a person's hand. No mention is made of taste.
The durian is:  Durian kutejensis Bacc., also known as durian pulu,
and was collecetd in Brunei. There is a related story in the issue,
p. 10.
