Quiz 5 Flashcards
Twigs moderately thick, with true terminal bud. Leaf scars are remote from one another.leaf scar has a horizontal top edge, with the bud perched above it. “4-angled” or winged ash.
green ash
What did analysis of their plastid data find?
a strong maternal affinity of V. appalchiana to V. grainifolia.
What type of data was used regarding the appalachian gametophytes?
plastid, and nuclear DNA sequence
Twigs are thin with opposite leaf scars, and true terminal bud. Bud scales are imbricate (overlapping)
sugar maple
what is different about sweet buckeye distribution?
It does not occur anywhere inside the glacial boundary
Sawtoothed sunflower
radiate capitulum

black locust
what did analysis of their nuclear data find?
V. appalachiana is not the product of interspecies hybridization, as previously postulated.
Buds are long, narrow and pointed. Scales are imbricate. Small semicircular leaf scars, and small narrow stipule scars extending off them.
American Beech
Chicory
ligulate capitulum
Elongate terminal bud, with valvate scales, stipule scares completely encircle twig. Diaphragmed pith type, filled and cross walls.
tulip tree
eastern ohio
underlain predominatently by sandstone, a relatively resistant rock, underlain by shale to the west. Deep valleys, but not in wearing away the intervening higher land, forming a landscape of steep-sided sandstone hills.

what is different about the distribution of hemlock (contrast with sweet buckeye):
Extends far to the north, well north of the glacial boundary.
What were the results obtained regarding the appalachian gametophytes?
Bayesian analysis of the 56 recovered DET1 alleles yielded a phylogenetic tree that was mostly consistent with the plastid tree.
