Biqsystematic Study of the Polygonum Pensylvanicum Complex (Polygonaceae)

Edin, Irene Catherine
Abstract
This study was initiated in the fall of 1980. During the summer of 1981 field work began, but due to some difficulties only preliminary work could be done. In the following summer of 1982, the major part of my research began and I really began to observe the relationships in these species, despite technical difficulties which resulted in few numerical data. Sampling and measuring of herbarium specimens led to analyses that highly supported what I had observed both in the field and greenhouse. There is still considerable opportunity for research, as many facets of these species are still not fully understood; for example, reproduction. I suspect that further investigations will confirm the conclusions of this investigation.
