Pleasant enough is the discovery of a new species to the ardent collector, but it must be an aggravation to the systematic botanist who would like to arrange the full Flora of a country while he is about the task. But with so much unexplored territory in our land, and with such enthusiast roamers as Mr. and Mrs. Lemmon, Rusby, Greene, Parish, Parry, and many others, new ones come to light, and the families of plants, over and over arranged, have again and again to go through the process. Here we have ninety-six pages of the proceedings of the American Academy of Arts and Sciences occupied with descriptions of new plants, or new notes about old ones, mostly made during the past year, and with more probably to follow the next year, making the completion of a full Flora of the United States a very difficult task. Still there must certainly be an end to these dis-coveries soon, and nearer and nearer the complete enumeration becomes possible. Over two-thirds of the pages are occupied with notes on Compositae which Dr. Gray has been closely studying of late in view of the approaching publication of the part of his Flora having special relation to this order.

As indicating the near approach of the end of new things in our territory, it may be noted that there are but two new genera described among the numerous species. One of these is dedicated to our well known-correspondents, the Parishes of San Bernardino. It is called Parishella, and be-ongs to the Lobeliaceae. It is a small white flowered plant, and will not perhaps do much to adorn our gardens. In the more showy families of plants are some new Phacelias, Pentstemons, a Verbena, and some Leguminosae.
