The Phylogeny of the Southeastern United States Hymenocallis (Amaryllidaceae) Based on ISSR Fingerprinting and Morphological Data

Author : Catherine M. Bush

Additional Authors : Dollie Rollins, Gerald L. Smith

ABSTRACT The phylogeny of the southeastern United States species of Hymenocallis was investigated using 23 ISSR presence/absence characters and 10 qualitative and quantitative morphological characters. Maximum Parsimony (MP) and Neighbor Joining (NJ) analyses with bootstrap replicates were performed in PAUP. The total combined data NJ analysis showed several supported clades with morphological synapomorphies. Hymenocallis choctawensis …

Confirmation of the Hybrid Origin of Eupatorium 3truncatum (Asteraceae) Using Nuclear and Plastid Markers

Author : Michael R. McKain

Additional Authors : Mark A. Chapman Amanda L. Ingram

ABSTRACT Eupatorium 3truncatum (Asteraceae) is distributed throughout the eastern United States and is thought to have originated from interspecific hybridization between E. perfoliatum and E. serotinum. This study confirms the hybrid origin of one E. 3truncatum population in central Indiana through analysis of DNA sequence data from nuclear ITS and corroborates the morphology-based hypothesis that …
