I just learned of the passing of Bo Karl. I first met Bob while I was an undergraduate student at Louisiana Tech in 1964 or 65. I was taking an agronomy course and was required to make a grass collection. There were a few grasses in my collection that I had difficulty identifying. I was told by my general botany professor to talk with Sr. Karl. He could identify them. That began a life long friendship. I never studied under Bob but we kept in touch regularly. After I received my doctorate degree and began teaching at The University of Alabama, he and I regularly visited each other and traveled together, culminating in a three week Nicaraguan trip. We met several times after his retirement and move to Cairo. We, along with several other Alabama botanists, published a check list Alabama plants. It is certainly sad to hear about his death. He lived a long, fruitful life.
