Well I couldn't find any pictures of A. crassiflora or A. microcarpa, so those are my last two guesses.  I did like the A. cornifolia flowers as a suspect, but found multiple pictures. 

I'm not in Oscar's class, but I too have eaten fresh ackee.  It wasn't very exciting.  I much prefer them cooked.  To piggyback on Oscar's comment, make sure you remove all of the pinkish red strings inside.  They can sometimes "hide" underneath folds in the aril.   

I grow many types of fire chiles:
Scorpions (Moruga, Trinidad Butch T, Trinidad Chocolate, Yellow Moruga)
Bhut Jolokia (Red, Peach, Chocolate)
Jay's Peach Ghost Scorpion
Carolina Reaper (just starting these)
Trinidad 7 Pot (Yellow, Jonah, Douglah)
Red Rocoto
Habanero (Roatan Pumpkin, Caribbean Red, Chocolate)
Yellow Mushroom
Chocolate Scotch Bonnet
Malaysian Goronong
Black Naga
Aji Lemon Drop
Naranja Picante
Devils Tongue
Trinidad Perfume (not a true fire chile but one with great characteristics that is great for blending when making sauces)

That is an impressive collection!  Do you grow them to eat yourself or just for the challenge?

If you come down south to Miami, I have several varieties I can share.

Here are a couple of websites with simple steps to build worm compost bins.

If you are heading to the West Coast of Florida, I would recommend a visit to Naples Botanical Garden.  I was there recently and the landscape design is quite impressive.  http://www.naplesgarden.org/live_map.shtml   Fruit trees are interspersed amongst the various collections and in groupings as well.   The do have the 'Silas Woods' sapodilla.

You can find addtional information here:

If you can find a kind soul with a tree, these will propagate from large cuttings.  I got a 50% take on stems that were 2 feet long and 2 inches plus in diameter.

here in Taiwan i am not sure if red/purple fruit are self fertile or if we have natural pollinators, but red here are commercially grown and no hand pollination.  Sometimes i wonder about hawk moths.

That is a good observation.  Moths, bats, some species of bees and even a butterfly in the Maduca genus are reportedly possible pollinators.  Another possibility is that the self-pollination trait has been cross bred into a red-fleshed type.

Red is usually said to be Hylocereus polyrhizus, not undatus.  they seem to hybridize OK.  but identification of Hylocereus genus seem very hard.

This is a very common misconception - identifying Hylocereus species based on the flesh color rather than the traditional morphological characteristics of the flowers and plant.  Looking at the original descriptions by Britton and Rose, they made no such distinctions. Some of the distinguishing characteristics related to stems used by researchers are number of spines (ranging from 0 to 8 or more per areole), distance between areoles, depth of the undulation between areoles, stem color, and those that apply to the flower are too numerous to list but include flower size, color, whether or not the stigmas are forked, etc.

Hylocereus also seem to flower based on photoperiod, so some farms can use lighting to try and control fruiting time more.  it is getting close to a 12 month season here.

Off-season flowering can be induced through the use of KNO3 or artificial lighting.  The former has been done by placing 75W incandescant bulbs between the rows for 2-3 weeks. The key is to insure that light strikes all surfaces of the plants.  If done successfully, flower buds will appear in less than one week's time after the lights are discontinued. The use of plant growth regulators can also be used to promote early flowering or to delay flowering.

I personally also notice huge variation in flavor based on dirt type.  you can almost taste the soil int eh fruit sometimes, so fruit grown near dirty areas often have horrible fruit taste i think.

Interesting observation.  Sounds like something worthy of further study. :-)

My wife said that i better not get cuttings from USA without a phyto-report because you never know with the thai customs. Most of the time they are easy but if they want to give you problems (aka get money out of you)  then they sure have something when you receive a  plant with a phyto-report.

If you want to be totally above board, you might have to get a CITES permit as well.  I'm not well-versed in this area, but from what the link below indicates, the permit would be necessary for most cacti coming into or out of the U.S.

Jay, I'm sorry for your loss.  Hopefully you will do better with the ladies soon! ;-)

I've noticed on my MIA-1 seedling that stems which ultimately have female flowers on them always (or nearly so) have a male on the end.  (I'll get on the pictures tonight.) Is that the case with other varieties?

i really wanted to fruit this one years ago, as a newbie...and it got ravaged by the cold...much faster than the other varieties I had growing at the time...

has anyone tasted this one? or is anyone growing it?

Zamorano looks so dark red!!

I've got a couple of cuttings going that I got last year.  I could break you off a piece if you want to give it another go.
