Grin Most of the fruit we grow in the UK is the same family - they are
all in the rose family :-)

Rose family includes apples, pears, plums, damsons, apricots, medlars,
blackberries, raspberries, strawberries etc (as well as lots of our
ornamentals and wild flowers).

The key thing to look at is the flower - 5 petals, all separated at the
base (and other characteristics which Stewart will be able to tell you
but I can't) - if you look at a few, you will see the basic similarity.
And that the flower is very different from redcurrants, gooseberries,
rhubarb.

But within the Rose family, there are a large number of genera,
including Malus = apples and crab apples, Pyrus = pears, Rubus =
raspberries, blackberries etc,

And in particular, Prunus includes plums, damsons, greengages, bullaces,
cherry plums, cherries, sloes, apricot and peach. All things with a
stone. So you were right in spotting that similarity.

But almond is Amygdala - don't know why, because the fruit is very
peach-like - help, someone?

(That's the trouble with plants. The more you learn, the more questions
you find to ask)

Cherries, apricots, and almonds are not part of the Rosa genus. They
come under the Prunus genus, although they actually come under the
Rosacae family. I always think the genus is a much more accurate way of
identifying plants' common characteristics. the almond is a Prunus.
Amygdala is the Latin name for the bitter almond.
