Can I play too? N.B. My botanical credentials are nowhere near as
good as the other posters, but I've done a fair bit of work repairing
corrupted text. I probably spell things right, but may not identify
correctly, or recognise obsolete names, so don't take my word for it.
Corrections would be appreciated.

CARPINUS PIRAMIDALIS FASTIGIATA BETULUS
Carpinus betulus
f. pyramidalis fastigiata?

+ + +
No. Likely
Carpinus betulus 'Fastigiata' (syn Carpinus betulus var pyramidalis)

Remember if it is a forma it is a name under the ICBN.
Such names can have at most three parts

CITRUS TRIPTERA TRIFOGLIATA FALSO ARANCIO AMARO SPINOSO
Poncirus trifoliata? Common name: trifoliate orange.

+ + +
This is a creative guess, especially in view of the "amaro". The "spinoso"
does not hurt either

Quercus borealis, or maybe Q. borealis maximus Common name: red oak

No. Quercus rubra (syn Quercus borealis)
