What is this nut tree?
 

This small tree grows along roadsides close to the bank of the Colo
river west of Sydney. This is a warm temperate zone, with good
rainfall.

It has fruits containing nuts.

The internal structure of the fruit looks something like a mangosteen,
but the thin pulp has an astringent flavour.

Inside the the thin shell is a pure white nut. It tastes pleasantly
mealy, but not delicious. I spat it out in case it is poisonous.

I don't think it is a native Australian species. There are a lot of
garden escapes in this area.

What species is it?

Nice photos.

It has fruits containing nuts.

Or, possibly just large seeds in a fibrous fleshy fruit. Technically,
a "nut" is a type of large dry fruit with a hard fruit wall protecting
the seed.

As no doubt you know, you really shouldn't be tasting unknown
plants. Some can hurt you.

Again, that's risky. I was thinking that the tree vaguely resembles
_Aleurites_ spp. [Euphorbiaceae], which reportedly can have seeds
poisonous enough that even one could kill a person.[I don't actually
think it's an Aleurites, however.]

Sorry, but I'm not at all sure what it might be. Your photos are
clear, and if someone is familiar with the plant he should have
no problem identifying it for you.

Malvaceae, s.l. perhaps? Palmately veined, alternate leaves,
apparently a terminal flower/fruit, ovary superior and slightly
stipitate-based...

for example [clearly not the same plant but a bit reminiscent]

Thanks for that lead. In fact Thespesia populnea it is.

http://www.nybg.org/bsci/belize/Thespesia_populnea.jpg

and many other images,

Nuts they are, in the sense that I had to use a nutcracker to crack
the shell, thin though it is.

Cornucopia II cites several sources, at least one of which must claim
that the nuts were candied.

Tasting the unknown? I have survived for decades by a touch on the
tongue. If tongue still there, nibble on a minute quantity. Spit. Wash
out mouth with water. Spit again.

Cheers

Richard

Since you've now identified it as Thespesia populnea, it's not listed as
native to New South Wales. However it might be native to Queensland. (T.
populnea occurs in coastal locations over much of the tropics, but
there's also confusion with T. populneoides.)

(The reference I had for T. populnea being present in Queensland - the
Millenium Seed Bank target list - seems to have disappeared from the
face of the web.)

Thanks for the extra information. Do you know anything about the
edibility of the nuts of Thespesia populnea?

The leaf and flower buds are said to be edible raw or cooked. The
seeds are applied to scabies and other skin diseases, and are rubbed
on swollen joints. The yellowish juice extracted from young fruits is
used to treat insect bites, gonorrhoea, ringworm, and migraine
headache , and is also used for fistula, psoriasis, scabies, sprains,
and wart removal:

Exactly. But what I wonder about is why all the sites I am able to
Google are coy about the nuts.
