Other claims from this paper (10)
- Observation Subsp. siskiyouense does not represent a valid taxon.
- Observation Var. greenei does not represent a valid taxon.
- Observation Varieties diffusum, douglasii and glabrum are recognized with distinguishing leaf morphology and geographic ranges.
- Observation Varieties neomexicanum and torreyi are recognized with distinguishing leaf morphology and geographic ranges.
- Association Leaf morphology was geographically correlated.
- Method / resource Some numerical methods could not discriminate all taxa.
- Observation Early leaf morphologies of individual taxa appear genetically fixed.
- Observation Late leaves tend toward a single morphology under environmental constraints.
- Observation Flavonoid analysis found no variation within or among infraspecific taxa.
- Association The presence of flavanones supports presumed close relationships among four sections.
