E. D. Merrill commented on Rumphius' plant and it's distinction from Loureiro's in his commentary on Loureiro's Flora Cochinchinensis.   "From the local name cited by Loureiro it appears that his specimens were from Indo-China.  His description is manifestly based on actual specimens, not on the pre-Linnaean Musa uranoscopos Rumph. (Herb. Amb. 5: 137), cited as a synonym and the source of his specific name. In my work on Rumphius (p. 149) I referred this to Musa paradisiaca Linn. But I am now convinced that what Rumphius actually had was a form of Musa fehi Bert. as he describes it as having erect inflorescences; the term uranoscopos used by Rumphius is merely a translation of the Malay toncat langit, literally meaning to look at or watch the sky."

I have not yet seen Rumphius' Herbarium Amboinense but Cheesman 1948a gives Musa uranoscopus as Rumphius' spelling for this plant, unlike Merrill.  It may be tempting but it would be dangerous to try to differentiate Rumphius' and Loureiro's plants in the literature based on their spelling.

Musa uranoscopos Rumph. was re-named by Linnaeus as Musa troglodytarum although confusingly he also included what we now know as Musa balbisiana Colla within that entity.
