According to the comment posted below by HMF-user Drasaid, "Henrietta's Pink Picayune" is not a synonym for "Picayune", but is actually another rose altogether.

"Highway 290 Pink Buttons is the same as the old pink Picayune in the "Everblooming Roses" book printed early in the 20th century. I know, because my family had the pink Picayune in the front yard for decades and we knew it by that name. Suspecting it was the same as Hwy. 290 Pink Buttons, I sent some cuttings to Antique Rose Emporium who grew them and confirmed it was the same plant. That means this rose has an older history than Rouletti. It is very similar to Rouletti only having more petals. I sent some to RosePeddler who was selling it under the name "Henrietta's Pink Picayune" to distinguish it from the other Picayune in commerce and to honor my old aunt who preserved the bushes in New Orleans (which, alas, are no longer with us.) Hwy. 290 Pink Buttons probably was brought from New Orleans which was the only place with rose vendors for hundreds of miles for a long time. Thanks!"

Can this synonym be deleted from "Picayune" and added to the "Highway 290 Pink Buttons" file? Thanks in advance.
