Seventy-six different species of milkweeds or Asclepias grow in the United States. In 1948 Woodson published a monograph about them. This is the first time his study has been updated.
Living plants are very different from dried, pressed herbarium sheets. This study was done from the living plants. Each Asclepias species was tracked down, photographed and studied. Flowers were dissected, diagramed and photographed. Pollinaria were studied. Many of them were germinated from seeds to compare germination styles.
Historical papers about the different species were tracked down, translated when necessary and used in the descriptions of the individual species. Both historical images and photographs of the living plant illustrate each entry.
This book is written to be understandable by both the botanist and serious amateur interested in these fascinating, complicated plants. It is printed on full size, heavy paper, spiral bound and split into three volumes for easier handling.
