Few European botanical collectors have been better known in America than Mr. Roezl, who recently died in Austria in his 62d year. A large number of plants bear the name of Roezelii in his honor. The writer of this first met with him many years ago, in a very interesting manner. He was alone in a piece of woods along one of the rivers in Missouri, and examining minutely some specimens of what was to him then a rarity, the true Chestnut oak, Quercus castanea, of which he had found before only a few scattered specimens in Pennsylvania, when he observed a man kneeling by a spring, and seemingly washing out a pocket handkerchief. Advancing, the writer found the mart engaged in washing out the pulp from the fibre of a species of nettle which grew there. The fibre was very white, slender and strong, and the stranger was very enthusiastic on the prospective value of the nettle fibre. It proved to be Mr. Roezl, and the meeting of two friends, who had long heard of but never seen each other, in that lonely piece of woods, many hundreds of miles from each others' home, the reader may well imagine was a very pleasant one.
