Discussion
The single 1952 collection of Rosa palustris from Lake of Three Fires State Park (ISC), Taylor County, southwestern Iowa, is about 430 km northwest of the nearest known collection of the species, in Missouri. The species was probably introduced. It has the most serrulate leaflet margins of all roses in North America; the stems usually have short, stout, curved infrastipular prickles, rarely without armature.
Rosa ×palustriformis (Rydberg) Voss (R. carolina var. aculeata Schuette, R. michiganensis Erlanson, R. schuetteana Erlanson) refers to putative hybrids between R. blanda × R. palustris from Maine, Michigan, Ohio, and Wisconsin. Rosa schuetteana is morphologically intermediate between the parental species; R. ×palustriformis is more similar to R. palustris. Rosa blanda and R. palustris differ by: branch armature (R. blanda unarmed or with sparse prickles or aciculi, R. palustris with stout, curved infrastipular prickles or unarmed); length of each auricle (R. blanda average 4.8 mm, R. palustris average 2.6 mm); petioles and rachises with pricklets (R. blanda rare, R. palustris common); leaflet serrations (R. blanda serrate, acute, teeth 10–26 per blade side, R. palustris serrulate, slightly blunt, teeth 20–30 per blade side); pedicels stipitate-glandular (R. blanda eglandular, R. palustris almost always); hypanthia stipitate-glandular (R. blanda eglandular, R. palustris almost always); inflorescences corymbs (R. blanda rare, R. palustris common).
Root decoctions of Rosa palustris were drunk by Cherokee to treat diarrhea (W. H. Lewis and M. P. F. Elvin-Lewis 2003). In Maine, R. palustris hips, including their achenes, are gathered about February, flattened, dried, and ground into flour for use with ground wheat to make leavened bread. The bread has a red color and a fine taste reminiscent of tomatoes (Arthur Haines, pers. comm.).
