The study of the vegetation of one of the natural coastal
prairies in Oregon was undertaken for the purpose of describing
some of its synecological features. Specific objectives of the study
were to describe certain plant assemblages in the study area, present
phenological relationships on some of the assemblages, and...
The vegetation of the Oregon coast is characterized by a
variety of stages of plant succession which are repeated widely
throughout the sand dune area. During the years from 1960 to 1963
the gradation of upland sand dune succession was studied on 48 plots

occupied by the species and...
Setaria lutescens (yellow foxtail) plants, grown from five seed

Iowa, Massachusetts, Pennsylvania and California. Morphological
and physiological differences between biotypes include: plant
size, growth habit, time required to mature and reproductive capa
city. Most significant is the prostrate habit of the...
