Pomin di dama (dame's apple) is mentioned in Volkamers second book "Continuation der Nürnbergischen Hesperiden" (1714)
My scion comes from the Royal Gardens of Hetloo, Netherlands.

I have been to the Royal Gardens at Hetloo, Netherlands, the gardens are absolutely stunning. How is it that you got budwood from a tree at the Dutch Royal Palace's gardens? - Millet (1,232-)

That is a really cool looking fruit. What exactly is "Pomin di dama" ?

Amazing co-incidence - I'm off to Het Loo on Wednesday, and have arranged to be shown around the citrus collection by the garden's curator Ben Groen.
I will report back!

Mike, the view of the gardens from ontop of the palace's back veranda is absolutely stunning. - Millet (1,239-)

I'm looking forward to visiting the palace!

I suspect this is a miss-translation of Adam's Apple. Usually called Citrus lumia - although lots of other botanical labels. See

However, I have a list of all varieties at Het Loo and it is not there. Also, I don't think there is a variegated form of Adam's Apple. So, a bit of a mystery.

The Dutch citrus collection at Het Loo has approximately 30 citrus trees that are over 200 years old. These old tree have been in this collection their entire life. See the link below. - Millet (1,229-)

is definetly not Citrus lumia. It is clearly a variegated C. myrtifolia. Volkamer names it the way he has come to know this plant. As most of his plants came up from Italy there is an Italian name. Pomin is a deminutive of apple (a little apple), di dama -of the lady.
I got the budwood from a friend who got it from a friend who got it from a gardener in Hetloo. It is likely that they do not list the plant in Hetloo under Volkamer's denomination. Look after variegated Chinotto.

Yes, Palace Het Loo has several trees listed in their database as Citrus aurantium var myrtifolia 'Variegata'.
I had already noted that I should take some pictures of this variety, as I haven't seen it before.
I think that Laaz - King of Citrus Variegations - has a similar type in his collection.
While I'm there, I will ask permission to put the Het Loo list of varieties somewhere on my website.

Yes I do have a variegated Chinotto. I have had it for years, but it still has not flowered or fruited. I grafted another tree last fall to keep in a container to see if that will get it blooming.

does your budwood come from Europe? Or are there other clones of v. c. than the old one?
Robert

No the budwood is from the USA. I am not certain the origin.

Here are some photos taken yesterday of the variegated myrtifolia in the Dutch National Citrus Collection. This was at the smaller section of the collection, held at a private estate called 'Twickel'. I am preparing some webpages about the Dutch citrus collection, but it takes some time.
To give you an idea of scale, I would guess the pot is about 1m (3'3") across, and a little more in height.







The variegated form did seem to have far fewer fruits than the standard one, but as you can see, there was one ripe fruit and several tiny ones.

Mike, thank you for this outstanding post. When I visited Het Loo, the citrus trees must have still been inside, as I did not see a single citrus tree. Actually, I did not even know that there was a National Dutch Citrus collection. Again, great post. - Millet (1,212-)
