When I first read the field notes of Annie Alexander and Louise Kellogg, I was fascinated by the descriptions they wrote about the places they went and the plants and animals they found there. By publishing my field notes on the Internet I hope to follow a little bit in their tradition. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The name was first used by Pedanius Dioscorides in De Materia Medica (c. 40) as the Greek name for an uncertain marine plant (probably a species of Acetabularia), derived from andrós (genitive of an?r man) + -akes, derivative of ákos cure). The root was probably misconstrued by Linnaeus as a compound with Greek sákos shield, when applied to the land plant in the Primulaceae, meaning andros, male, and sakos, shield, alluding to anther shape.
