Emergent properties derived from the integration among descriptive variables were explored in three related grass species, Achnatherum lemmonii, Achnatherum hendersonii and Achnatherum wallowaensis. Different levels of organization were compared: individuals, populations, species, species-pairs and all three species combined. Emergence was seen at all levels with populations having the lowest degree...

Emergence was seen in the differently aged needle primordia, generally most noticeable in the oldest and the least apparent in the youngest. There was also a negative relationship between variation...
