Murraya exotica vs Murraya Paniculata?

I found this comment on a website:
http://www.hear.org/pier/mupan.htm

Comments: "Murraya exotica L. is said to differ from M. paniculata in the larger leaves (less than 4, not 3-7) cm long and petals rarely over 2 cm long (not sometimes over 2 cm long)" (Welsh (1998), Smith (1985) and Stone (1970) list them as synonyms).

My murraya is blooming now as the photo shows. I measured the leaves and they are all exactly 4 cm. The question is this: can anyone figure out from the comment above, which murraya I have? Exotica or Paniculata? Are they really the same plant?

Thanks in advance!

Interesting. I did a search, and am now more confused than ever. Seems they are synonyms... I have one I grew from seed, it is a beautiful small plant. Wish it would bloom.
