I have no idea, only that it does not sound like any type of guava due to the hard shell. It could very easily be in the same family though, Myrtaceae. This is a major plant family in that part of the world... you might even try looking at photos of genera within the Myrtaceae that have edible fruit, if you think it really does resemble a guava outwardly.

Good luck, sounds like a fun mystery...

The leaves and fruit look an awful lot like feijoa, but the description of the inside does not.

Great find!!!!

I have no idea since I would have said guava too until you described the interior.

Thought it might be Aegle marmelos, but I don't think so.

Might help to do a image of the fruit bisected laterally and longitudinally to show off the interior along with a small centimeter stick for measure.

It looks like a pineapple guava. A Feijoa species. The fruit interior is sweet when fully ripe.

The above pictured plant has non-silvered leaf undersides, external veining on the fruit, extreme right-angle growth habit, and an uncurled residual calyx, all different from feijoa characteristics. Feijoas have a long thin stem like cherries, they do not form right off of woody growth.

Also, feijoa would not be "wild" in India although it is grown there in cooler regions.

Looks nothing like a guava. The leaves are too small and the wrong shape. the branches/trunks look nothing like a guava. And the fruit looks nothing like the fruit ive seen in any guava tree I own.

I did try cutting the raw ones, it did look like Feijoa, the ripe one was different. Next time when I visit the farm I will check again.

The folks around assumed these to be some wild plants, not sure who had planted these over there.

Is Feijoas good for cultivation?

Thanks,

All guavas, and feijoas (which are excellent fruit in my opinion much worthy of cultivation), are soft all the way through from the outside to the seeds. There is no rind or shell to speak of, only a different colored outside to the fruit, that can hardly even be called a "skin".

I agree with Goyo about the leaf differences, but these can vary so much within one genus even...

Hope someone else out there has some ideas for you...

Where in India are you? In the U.S.feijoas do not fruit well in the hotter climates, or in colder short-season climates. They are grown in India, it should not be hard for you to find out what region.

There are three species in the feijoa's genus, we need pictures of some of your fruits cut open.

I did look at a list of perhaps a dozen wild India fruits, none matched yours. Is your fruit planted in orderly rows?

good images of feijoa here, including flowers. Not the same but very similar.

Here is a link that might be useful: pineapple guava

Have you seen them in bloom?

perhaps the botanists in the NAME THAT PLANT FORUM .. might take a stab at it ...

...good suggestion, there are several members over there who either put in the ID time or just know a ton of stuff. If the OP here does not follow up, I will re-post the picture there.

Thanks for the suggestions Ken & Larry.

I am planning to visit my farm this weekend, I will try to get photos of inside of the fruit.

Will post both of those in the other Forum as well.

Got one picture of it using a simple phone camera. Hope it helps.

Thanks,

Your fruit does not have the distinct 4- or 5-lobed pattern typical of the interior flesh of feijoas. The rind thickness is similar, your fruit is more seedy. I do not see evidence of the hard shell you first mentioned, unless it is very thin.

If this is wild, native fruit, some person local to your farm will know the name.

Try posting the images on the Name That Plant forum as mentioned above. You might have to rename the images to re-post them there, otherwise just provide links to these.
