Other claims from this paper (8)
- Observation Morphological analysis distinguished P. rivinoides from the P. icosandra complex.
- Observation The rarely collected P. meziana was distinguished.
- Observation New chromosome counts were 2 n = 36 for P. rivinoides and two complex representatives.
- Association The morphological axis correlated with an elevational cline.
- Observation P. rivinoides occurs between sea level and 2,200 m.
- Observation P. rugosa occurs between 1,000 and 3,400 m.
- Mechanism Authors hypothesized introgression from P. rivinoides into P. rugosa generated the complex.
- Observation Authors hypothesized northward migration of the complex and possible ancestry of P. americana.
