Hybrid speciation in Erythronium (Liliaceae): a new allotetraploid species from Washington State

摘要: Abstract Erythronium populations from the southwestern Olympic Mountains of Washington, U.S.A. are tetraploid (2n = 48) and morphologically intermediate between two widespread diploid species this region, subalpine E. montanum low-elevation revolutum. The lie geographic elevational ranges revolutum exhibit a combination isozyme characteristics these species, possessing 11 alleles in common with four evidence supports their derivation above through allopolyploid hybridization, they described here as new quinaultense.
