Nice writeup CJ! I was previously aware of the 5 BG's you mentioned, as well as the debate between L.M. purpurescens and L.M. mystacalis.

I've read a lot of studies that argue the continued existence, and occasionally even the validity of L.M. Speciosus.

Are there any photos of Speciosus?

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
