You're holding an immature fruit (you can tell by that "hole" at the end).

It's either cydonia or pseudocydonia.

That's a very nice quince. Allow the fruit to ripen on the tree (autumn); wait until some begin to fall off would be my suggestion. They'll be a very light green or yellow and quite large. Quince are best used for making jam or preserves of some kind.

I do not think that this is a quince. Firstly from the trunk this is a large tree and quinces are small trees or large shrubs. The bark looks just like pear bark.

Secondly the leaves are glossy and a pointed oval. Quince leaves are a more rounded oval and have a felted greyish underside and are dull.

Thirdly the fruit has no bloom. I think this is a pear.

What sort of seeds are inside? I don't recall what quince seeds are like, but of course pear seeds resemble those of apples. The fruit will also have the characteristic gritty quality of pears. and can you describe the blossom? Here's a photo that also shows the texture of quince foliage:

I'll try to get some more photos. I'll crack one open and take of picture of its insides.

I think it's a pear also, not a quince.

I have seen quince shaped exactly like this, and to address Flora's comment, there are such things as quince trees. I have two of them and they are not what people refer to as 'flowering quince' a shrub. Depending on the variety, some quince fruits get quite large. As large as a pear, for sure. This looks a lot like a pear tree, however. But, I'm not sure. If they don't ripen or ever get soft, it's a quince. LOL.

A quince fruit is similar but a littl emore rounded (less long and oval). The leaves (on tree) are definitely a beautful sheen with a felt-like underside. I fell in love with quince the fruit, the leaf and tree (haven't even tasted one) last summer. I now understand why artists painted them in still-life paintings. They are utterly gorgeous with a glowing yellow, sweet fragrance and will last on the windowsill for a long time just scenting the room. The leaves have a similarly fresh color with the texture being practically graceful and endearing (sorry, not sure how to describe a leaf but these are just gorgeous). They could make a beautiful wreath practically by themselves. I was lucky to take a cutting and it sprouted leaves so will be the happy mama to a quince tree. If you've never seen a quince with leaves, take a gander and you may understand why I'd rave about them.

In another message, Joe provided the name of the fruiting quince as Cydonia oblonga.

Calliope - maybe I was not clear enough when I used the word 'shrub'. I know the difference between Cydonia and Chaenomeles and I wasn't referring to the latter. Obviously quinces can get very large, even tree height, but I have never seen one with a single, large diameter, stout trunk like an old pear. They generally have a spreading,lax, branched habit and that is why I used the word shrub.
Although the fruit in the picture could conceivably be immature quinces (although they are not particularly knobbly) the leaves twigs, bark and trunk in the photos look exactly like those of an ancient pear tree, not a quince.

As back2eden says, the scent will clinch it when the fruit matures.

We'll go with pears for now. I'll keep an eye on it though.

Definitely a pear tree.
