My Lansiums have flowers

[Mike T]

When I first was looking for some Lansiums to plant I wanted duku, longkong and duku-langsat and was not so keen on langsat. There weren't many around and I was lucky to get the ones I wanted although Duku Terrenganu rather than Duku Jahor is what I would have liked but you just have to take what you can get. They have served me well and produced fruit for a few years now with the duku-langsat having the best fruit in my opinion and the biggest fruit as well. I jut went out to look and they are in flower now.
The duku has bark with corky patches all over as dukus seem to do a bit and there are a few flowers and small fruit.

Two of my 3 longkongs are flowering and my largest one has a few flowers coming but isn't going crazy.


The duku-langsat is a marcotted tree and it is my favourite of the lansiums and it seems to have a few flowers and small fruit.

I prefer lansiums with a slight grapefruit taste. in the philippines they call them native Lanzones. The Duku or Longkong sell for a higher price and can be pure sweet with no tartness whatsoever. What are the differences you see in Duku and longkong ?

[Mike T]

Ben they all have that grapefruit taste in them. Lansones/langsat are a thinner more upright tree and the fruit are paler skinned in looser bunches and more egg shaped. There is a bit of latex in the fruit skin and the fruit are smaller and a little sourer. Lansone Paete is one I could have had and they are alright. They are more cold hardy than the ones I have and can be slower to bear.There are fruit in Borneo that look just like big lansones but are sweeter and people call them langsat.
Lansone / langsat are classified as such due to their fruit characteristics but I have seen papers that say there is not a genetic basis to the names we use to group them.

Nice going, Mike! Centuries ago, I spent a whole school year in Manila and that was when I contracted the Lansium Crazyium tropical disease. These are by far my #1 fruit.

Waiting, waiting, I planted 4 lansium seeds 15 years ago and they don’t bloom yet, also 2 Long kong and duku 4 years ago, waiting, waiting...

mike these duku, or langsat, or long kong so much confusion around them, my mate in whyanbeel has trees which he calls duku but who knows which of these they actually are.  They are an tall thin tree probably 15+m tall and you cant climb them to harvest as the branches are too small.  Luckily he has a large native tree nearby which he climbs and abseils down to pick these "duku".  Im not sure how others are able to pick them without a cherry picker or something as the branches grow upright and are relatively thin.

not from my experience eating them in malaysia, and the philippines. the ones that sell as duku or longkong can be pure sweet with no subacid whatsoever

[Mike T]

Ben I meant grapefruit flavour is in all and independent from sweetness. Remembering that each name is general and has a number of varieties which fall under them. In terms of acidity the sequence goes , koksan is the most sour, lansone/langsat are sweet sour with some varieties a little more acid than others, duku-langsat and longkong are sweet with a little acidity only and duku are sweet with almost no acidity.
Lansone is the Philipine word for Langsat. People when thy refer to varieties or accessions usually use two words with the second being a location or name such as: Lansone Paete, Langsat Uttaradit, Duku Jahor, Longkong air. Some of the Borneo and indonesian ones generally seem to fit between the groups and don't have stable names by the looks of it. Why there is genetic diversity seems to be because they have been in cultivation so long and that the good ones are a result of closely related species being crossed.
Tropo sounds more like langsat especially if the fruit are not crowded on racemes and are egg shaped. A picture would help.

Hi
I have a very rare lanson .I don't remember the name, but it have only sweet taste, no grapefruit aftertaste. Really delicious but inconsistent bearer.

[canito 17]

Hi Mike
I have 2 types of baccaureas that taste similar. Sweet but more subacid. Give me your opinion. Latter I can post some pics

[Mike T]

Do the names Lansone Jolo or Conception righ a bell?  markets and grafts fruit way faster and langsat can take 10 to 15 years to fruit from seed.Baccaurea differ so much between species and you could hav rambai and mafai or 2 different tampois. A pic or discription helps and all members of this genus don't taste much like the langsat group in my opinion.

[canito 17]

If I remember well the name is ruasan Lanson. My taste is more sweet and sour, I like that baccaureas. One with yellow seeds and the other with violet seeds. They are ramiflora.

[Mike T]

B.motleyana is the Rambai and these have white/yellow seeds. B.ramiflora is burmese grape or mafai and these have purple seeds. They are quite similar and most people prefer rambai. B.pyriformis is like a larger fruited glamorous version of these and the tampois are usually much bigger with thicker skin.
