Photographs of wildflowers were taken in situ, in the field,
at the Saylorville Lake Recreation site, with the aid of a 35 mm camera,
using standard photographic methods. Bracketed exposures of the wildflowers
were made using Kodachrome and occasionally Ektachrome, color-positive,
films. Images, selected from the resulting pool of photographic slides,
were scanned into a Macintosh computer with the aid of a Nikon Coolscan,
slide scanner. Captured images were refined using Adobe Photoshop 3.0 software.
These images are stored in JPEG format, at a screen resolution of 144 pixels
per inch. They were imported into Adobe PageMill 2.0, for preparation of
these web pages. All photographs, except as mentioned in the "Acknowledgements"
section, were made by the author for the purpose of developing this guide,
and constitute original work.
Descriptions of the wildflower taxa presented in this web site are based
on flower specimens collected at the Saylorville Lake Recreation site, by
the author, during the course of this project. The specimens were prepared
according to standard herbarium methods, and collected with the permission
of the U. S. Army Corps of Engineers, under a collecting permit issued by
the Iowa Department of Natural Resources. Taxonomic descriptions included
in this web site are those of the author, and constitute original work.
Flowering periods given in the species descriptions are based on field observations
at the Saylorville Lake site or interpolated from various references. Species
identifications are based on the author's evaluations of the herbarium specimens
collected for this project, and are the responsibility of the author.
The taxa presented in this web site are grouped according to Family. Individual
taxa within Families are grouped by color, and may be accessed through the
Index to Wildflowers.
