More edible flesh than a lychee, yes. The skin being thin helps as well. Each fruit had at least 2 seeds, some had 3, and not every seed was same size. Maybe Luc or Raul could chime in regarding whether or not there seems to be much variation between trees.
There's usually 2 seeds inside, but some come with 3 and some of the big ones can have up to 4,as far as variability this is a topic that my friend Luc and I don't share same opinion, I have noticed adult trees that don't produce fruit over the years, other who set mediocre amounts of fruits while others have excellent production every year, the researchers who came to take material for DNA this last January found some trees with most male flowers than another's, maybe that is the case, Omar said he was going to start working on DNA This summer with the material (flowers) they took, so maybe there should be news soon, something Luc said that I agreed is that on the same tree can be fruit with different shapes some more rounded another more pointed but in general 95%of the trees produced fruits of the same flavor the only difference among these trees is size with some with slightly larger fruit, and amount of fruit set as I mentioned before, other than this I have been able to isolated 3 trees with some variations and this are the ones
1-Dream- 5 years ago when dating my now wife, we did a Canopy on las Juntas y los veranos Hills with Adventure tours company, we took a. Fast inflate boat from the maritime terminal, for 45 minutes to arrive to the boca de tomatlan Beach then a Mercedes open big truck to the hills once we reach the canopy set in the hills we start to ride a donkey all the way up, about 5 minutes riding I look to the woods on my right I see a large limoncillo tree but to my surprise the fruits were not yellow like regular, but instead a maroon, clay, or brick color! I was fascinated I thought of jumping off the donkey and get some! but mistakenly thought, it wasn't right as it was a guided tour, there was many tourists also on it, and the riders were on line uphill on a narrow road,
on the way back after all the exercise I just forgot about it, I had gone couple times to look for the tree but couldn't find it, it's a mistery, and I wasn't drunk! It was only about 10 in the morning when I saw it! Hehe, my goal next year is find this tree, as this year due to lack of rain in December those uphill trees didn't set fruit
2-sharpie: a young tree who sets only pointed fruit of regular size which is odd as most trees set round fruit, but what makes this one different is that the flavor is very intense I would say very sweet and very tart at the same time with the sweetness being dominant this is my favorite one, is a small tree and is shaded by many big ones...
3- sweety: this is at the top of a hill also a young medium size tree who develops perfect round fruit of average size but with a slightly deeper color going towards light orange on the shoulders, and the Prime ripe fruit is just sweet this is the sweetest limoncillo I have ever tried, I would say 90 sweet 10%tart..
This two trees are in very bad shape this year because they have been since last November with out rain, with Sweetie having some die back at the top, I went to collect some budwood last week but just didn't make sense as the tips look wrinkled od dehidration, the graft just wouldn't make it
