Hi
Here in Brazil, I found this species twice, in the cities of Angra dos Reis and Paraty, state of Rio de Janeiro and at sea level, Atlantic forest. At the time I went behind information about a supposed Abiu Rambutan and found the trees, I only managed to collect seeds from the tree of the city of Paraty, because there were fruits at the time, they are doing very well here in Minas Gerais.
I think these trees in northeastern Brazil are also close to sea level. For these states generally have Atlantic forest only on the coastal plain, the rest of their territories, or they are transitional bands, or they are what we call Caatinga, which is a semi arid biome.
Alexandre.
If you got the seeds from me they are originally from highlands Guatemala, so a sub tropical, and not surprising it survived. They have a wide range, so there are some that are more tropical. So all depends where you sourced them?
Oscar, is P. torta ssp gallifructa a highlands species in general, or does it just have a significant range? I haven't come across any altitude data on it so far.
