What is this,

hanging from a tree at the golf club.

[Rick]

Sort of looks like acorns, but I know they don't grow in clumps. Nice capture.

[Peter Dulis]

Seeds?

[julia]

Bottle brush seeds http://www.subtropical.co.nz/writingWeepingBottleBrush.html

[Carole G]

Julia beat me to it

[Marnie]

Julz beat me to it too!!

[Shutterbug]

Do resemble acorns, except for the way they hang in clusters.

[KoalaGardens🐨]

oh oh oh bottlebrush seeds :)

[LibbyLou77]

It looks like an Australian native

[LibbyLou77]

Oh yes, as KoalaGardens says (I should have read all the comments first)... Bottlebrush

[Valerie Chesney]

You have captured these bottle brush seeds so well....I have one big tree in the back garden & it looks like this at the moment.

[Angelika van Rooyen]

Bottle brush sounds right to me!

[Casablanca]

A bottle brush, how brilliant! My favourite plant when we lived in Australia.

[Joan Robillard]

Wonderful capture

[Beryl Lloyd]

Beautiful against the blue sky !

[Bep]

Interesting capture.

[Anne]

No idea Diana, but a fab shot. We could do with some skies like that over here!

[Lou Ann]

See, we learned something today. So cool and glad that @julzmaioro knew what they are.

[Jacqueline]

Are those gumnuts?

[Pigeons Farm]

lovely shot

[mittens (Marilyn)]

So interesting looking. I have no idea what it is.

[bkb in the city]

Great find

[Taffy]

I photographed these in Hawaii! I can't remember the name but if I can find a label from one of my photos, I'll come back and post. They're on the indigenous endanger list in Hawaii, btw.

[Margaret Brown]

No idea but I do like your focus

[*lynn]

unique, whatever they are!

[Rob Z]

I'm pretty sure it's the seed capsules from a bottlebrush tree (Callistemon) https://www.anbg.gov.au/callistemon/

[Linda Godwin]

They do look very cool

[Pyrrhula]

Looks like a bottle tree after flowering.

[Jane Pittenger]

How odd
