I don't know whether it's Pasithea caerulea or coerulea so can't help Mary Sue there, but as for her questions, "I thought it was from Chile, but it looks like >when it was published it was from Peru?" Chile was not administratively separate from Peru until 1778, and was not independent of Spain for several decades more, so a plant described in the late 18th century (as Pasithea was) might be cited as from Peru even though it came from present-day Chile.
