Taxonomy
Symphyotrichum rhiannon was formally described by Alan Stuart Weakley and Thomas E. Govus in 2004.[3]
Etymology
Kauffman, Nesom, et al., formally explained the etymology of the species as follows:[3]
[It] is named in honor of Rhiannon Weakley, whose desire to rest during a field excursion led the authors to further investigate..., and also in honor of the original Rhiannon, a Welsh goddess figure....
Informally explained, Rhiannon Weakley was the toddler daughter of Alan and Allison Weakley. She needed a snack and a nap during the 2003 field excursion.[4]
“Rhiannon hadn’t had a nap that morning,” says Alan Weakley, “and she had a little, ah, loss of composure.”
So the group plopped down to give Rhiannon a snack and a chance to rest. And there, growing all around, was [Laura] Mansberg’s mystery aster.
Distribution and habitat
Symphyotrichum rhiannon is endemic to Buck Creek Serpentine Barrens in Clay County, North Carolina, in the Nantahala National Forest.[3][5]
