My Machu Picchu is GRIN Pi 116159 (Ti 719). [
http://www.ars-grin.gov/cgi-bin/npgs/acc/display.pl?1130544]
It was originally collected on the slopes of Machu Picchu, Peru, in 1936, by Roger Stadelman. GRIN classed it as wrapper. In Stadelman's personal correspondence, he states that the grower of that tobacco (living on Huaina Picchu) called the tobacco, "Havana." So, at some point in time prior to 1936, Havana tobacco was introduced there. In the original accession documentation [
http://sun.ars-grin.gov:8080/npgs_public/prodweb.pdf0?in_vol=127&in_suffix=&in_page=060], it was labeled simply "white flower," though for me, it produces rich pink blossoms. (It was found growing at 2100 meters elevation, which may account for the difference in blossom color.)
A second variety collected at the same time and place (GRIN Pi 116160, Ti 720), also by Stadelman, is labeled as "red flower," and classed by GRIN as cigar filler. I have no further information on that variety.

EDIT: I assigned the name, "Machu Picchu" to Pi 116159, since at the time I acquired it from GRIN, Pi 116160 was listed as not available for distribution. So it appeared that there was only a single variety of tobacco from Machu Picchu. Now GRIN lists both as available. Once I was able to read Stadelman's personal correspondence (thanks to Jessica), I began calling it "Machu Picchu Havana."
