Oscar I believe it is also illegal to send seeds out of Brazil.Red the flesh looks a bit thin but if the taste rivals the best zibethinus maybe there is commercial potential on peninsula Malaysia and Thaiand even as a novelty 'variety'.In a few weeks I should have D.macrantha in hand and will report.I wonder if they will live up to Zostermans and other enthusiasts hype?
The flesh thickness is similar to a seedling durian and less than a durian bred for thicker flesh. Interestingly, the second fruit I ate only had one seed, and the third fruit, 2; the rest being aborted, leaving very thick flesh. All 6 fruits I bought were from the same tree. Fruit number three was a bit overripe and the flavour was strongly caramel with the lemon peel hint gone.
I wonder if there is a scientific measure of stickiness. D. testudarium is very sticky, D. zibethinus less so and D. oxleyanus least of all. After being exposed to D. oxleyanus, one usually finds durian to have an inferior texture.
