He's not listed it yet, he showed it in one youtube video! Yes cassowaries watch youtube too!
I have a huge seedling Longan and never seen fruit, it fruited once before cause there's seedling under it. A friend in the lowlands bought a place with a collection of different Longan verieties, only one tree ever gave fruit, it was a small one growing out of the chicken wire house, maybe just the sheer amount of manure did it.
Kakus and Isau is sweet and good. Still with rambutan you have to have good males to get good fruit set, many clones have been selected to throw female flowers. That's why some farmers spray some branches with a chemical that makes them throw male flowers rather then females, it's in the Rambutan research paper by RIRDIC i think.
The Borneo rare fruit book by A. Lamb is great as it gives many alternatives to Sapindace for us in wet lowland cliamte.
I would love to know peoples secret with keeping pulasans alive and growin to maturity, I have to have a mist spraying on the leaves in the dry to keep em alive, not even normal irrigation and mulch is enough during the dry season. Wind and full sun just makes the leafs fall off.
Tropo, I can spare you a kakus seedling if we ever meet up.
Rauls koloc should be a good replacement.
