Stem 4 — 8 dm. high, much branched. Laminae of the ground-leaves, oblong, more or less 
cordate, subpanduriform ; of the stem-leaves, narrowly oblong ; of the inflorescence, very variable. 
Inflorescence more or less leafy, especially below, branched, branches variable, whorls distant. 
Flowers in June and July. Fruiting segments smaller than in R. pulcher , subentire or dentate 
towards the base, strongly reticulated as in R. pulcher) tubercles 3, prominent, equal or unequal. 
Achenes frequently sterile. 
Many forms of this putative hybrid occur, some of which approach R. pulcher in the divaricate branches of the 
inflorescence, whilst others have the branches less spreading or even ascending as in some forms of R. conglomerates.
