Agnes Arber (1879-1960) was a British botanist who was a leading plant morphologist during the first half of the 20th century. She also wrote on the history and philosophy of botany. I argue in this article that her philosophical work on form and on how the work of the mind and the eye relate to each other in morphological research are relevant to the science of today. Arber's unusual blend of interests - in botany, history, philosophy, and art - put (...) her in a unique position to examine issues of form. Even her unorthodox ideas on evolution can now be seen as fitting in well with discussions of natural selection as the predominant engine of evolutionary change. Arber's views also throw light on present work dealing with developmental plant genetics and with the study of protein form. I will further argue that her marginal position relative to institutional science, while it may have left her vulnerable to criticism, also made possible her deep philosophical reflections on morphology.

Herbaria are collections of preserved plant specimens, primarily composed of paper sheets with pressed plants or plant parts attached to them. The most valuable kind of sheet is the holotype specimen. This is the specific plant that was used in describing the species by the person who first identified it. Botanists must reference the holotype when reclassifying or renaming a species. In the past, this meant either borrowing the sheet or visiting the herbarium in which it was housed. With digitization (...) of these sheets, there is much greater and easier access to this information. However, digital images are not substitutes for the sheets themselves. This article will discuss why this is the case, why scanning herbarium sheets is still worthwhile effort, and why the sheets themselves are still necessary to plant research. (shrink)

I argue here that Goethe's "delicate empiricism" is not an alternative approach to science, but an approach that scientists use consistently, though they usually do not label it as such. I further contend that Goethe's views are relevant to today's science, specifically to work on the structure of macromolecules such as proteins. Using the work of Agnes Arber, a botanist and philosopher of science, I will show how her writings help to relate Goethe's work to present-day issues of cognition and (...) perception. (shrink)
