Abstract

I have for some years been interested in a study of our thistles. During my study in St. Louis I had occasion to examine the rich collections of the Gray Herbarium, Harvard University, as well as that of the Engelmann Herbarium and the Missouri Botanical Garden, besides a considerable collection in the Parry and I. S. C. Herbaria. I should not attempt the publication of only a partial paper on thistles, but it may be some time before I shall be able to get together the manuscript lost in the fire. With this apology I present these notes.
