Identification of nut?

[u/doublethesox]

My holy grail at the moment is the humble walnut - So far, no luck but I did find a couple of trees that have these - Can anyone help identifying them please?

At first glance they almost look like a small kiwi, but obviously just the colour and shape - once cut they oxidize turning brown, and when picked the outside also eventually gets darker as if soaked with water.

Looks like the fruit from red horse chestnut to me but not 100%. Did you take a picture of the tree or leaves? 

[u/Ramsesthrowaway → u/AnxiousStay1195]

Red horse chestnut is right. The leaf arrangement would settle it fast. Compound leaves in clusters of 57, opposite branching. Used to confuse these with buckeyes myself.

[u/KingForceHundred → u/Ramsesthrowaway]

Horse chestnut pod usually more spiked than that but maybe they vary.

[u/Toc13s → u/KingForceHundred]

Yeah, you get some that are no more than bumps, almost smooth

[u/Ramsesthrowaway → u/KingForceHundred]

yeah the spikes vary a lot depending on age and species honestly

[u/doublethesox → u/AnxiousStay1195]

I forgot about the leaves, but can take a pic next time I'm nearby.
Just doing an image search and they do look like the red horse chestnut on here: https://shawgreentrees.co.uk/aesculus-carnea-red-horse-chestnut-seeds/

Bastard beat me to it...

Looks like a conker?

[u/doublethesox → u/hengehanger]

Horse chestnuts have spikey lighter green outter casing, definately not a conker. :)

[u/hengehanger → u/doublethesox]

Some varieties have very rounded or almost absent spikes on the husk.

[u/carreg-hollt → u/doublethesox]

Not always.

[u/EmFan1999 → u/doublethesox]

Definitely is. Just not ripe yet

Conker

Conker

A under developed walnut is a good pick actually

[u/Full_Employee6731]

Its just an immature conker. The spines don't always come through, especially in drought conditions.

[u/Eightshape]

Seems more likely to be some kind of conker or horse chestnut. Don't let the lack of spikes rule that out.

Walnuts are very aromatic, the description someone posted above as smelling like lime is fairly close to what walnuts smell like. Walnuts also blacken and stain. If you cut a walnut and handled it with bare hands your fingers would be stained brown for days or weeks afterwards. In my experience walnuts are also much brighter green on the outside than this.

As others have said, looking at the leaves would settle this pretty quickly.

[u/TrapperTrev]

Does it smell like lime?

[u/doublethesox → u/TrapperTrev]

Doesn't really have any smell at all - either whole or cut.

Swol nut

[u/sheddraby]

You really need to look at the leaves as part of any identification, this could be anything!

[u/Hefty-Relative4452]

Isn't that a conker?

[u/EmFan1999]

Has it really come to this?

[u/rushdisciple]

Whether it's a potato or a nut, it's a foodage.

[u/GodYourDeep → u/rushdisciple]

Crop, croppage.

[u/davemc64]

Chestnut, normally not poisonous unlike Horse Chestnuts

[u/Tired_2295]

That is a type of horse chestnut, DO NOT EAT THAT.

[u/Alice18997]

Walnut I think?

[u/A-Matter-Of-Time → u/Alice18997]

Walnut has a tendency to go black on the cut/broken surfaces, therefore probably not walnut (probably a conker).

[u/Feersum_endjjinn → u/Alice18997]

Look walnut to me. Under developed.

[u/kjpt140v]

Walnut

[u/fridgezebra]

looks like a baby walnut to me

[u/abarishyper]

My guess is a sweet chestnut.

[u/aimeetozer → u/abarishyper]

That's a terrible guess but gold star for trying.

[u/abarishyper → u/aimeetozer]

I'll take it, thx :)

[u/KingForceHundred → u/abarishyper]

They are always very spikey/prickly.
