At a glance one knows this flower to be akin to Robin’s plantain (p. 75), the asters and daisy. A smaller, more delicate species, with mostly entire leaves and appressed hairs (E. ramosus) —E. strigosum of Gray—has a similar range and season of bloom. Both soon grow hoary-headed after they have been fertilized by countless insects crawling over them (Erigeron = early old). That either of these plants, or the pinkish, small-flowered, strong-scented Salt-marsh Fleabane (Pluchea camphorate), drive away fleas, is believed only by those who have not used them dried, reduced: to powder, and sprinkled in kennels, from which, however, they have been known to drive away dogs.
