I, PART II, AND VOL. II, PART I, COLLECTED. BY ASA GRAY, LL. D. WASHINGTON, D. C. PUBLISHED BY THE SMITHSONIAN INSTITUTION. 1888. ADVERTISEMENT. The present volume comprises two separate installments of a compre- hensive work designed by the author to embrace a systematic synoptical review of the entire Flora of the North American Continent. Nearly forty years ago such a work, undertaken by the joint labors of our two eminent botanists, Professors Torrey and Gray, was arrested by the pressure of other duties, with the execution of the Polypetalous division of the DICOTYLEDONS, the first class of the great PH^ENOGA- MOUS series, and five orders of the Gamopetalse, including the great order of the Compositse. This comprises just the scope of the projected first volume of the present series. Assuming that the reconstruction of the first division — the Polypetalse— would occupy some 500 pages, to constitute the 1st part of Vol. I, this present 2d part of the volume is made to commence with the Gamo- petalse, the full exposition of which second division extends through the 1st part of Vol. II. The 2d part of Vol. II will probably be occupied with the third division of the DICOTYLEDONS — the Apetalse ; and Vol. Ill is designed to take up the MONOCOTYLEDONS. The present publication, therefore, though made up of two consecutive parts of different volumes of the work, may be said to be complete in itself in giving a complete view of the entire division of the Gamopetalse. The preparation of the work has been largely aided by the funds of the Smithsonian Institution. S. P. LANGLEY, Secretary S. I. WASHINGTON, December, 1887.

NOTICE. EXPERIENCE having shown that some years must elapse before this work can be completed, and a new impression of the part first published (in 1878) being called for, it is expedient now to issue the two parts, which together comprise all the Gamopetalous Dicotyledons, in the form of a single volume, under the auspices of the Smithsonian Institution. Both parts have been corrected, as far as could well be done upon the electrotype plates ; a supplement of eleven pages is added to the very recently published Volume I. Part II., and its full index has been made anew. The tabular enumeration of the contained genera and species has been transferred to the end of the Gamopetala3. To Volume II. Part L, a supplement of seventy pages is added, and a few pages have been recast ; a tabular enumeration of all the gamopetalous genera and species is appended, and a complete index of genera, species, synonyms, &c., — making an extension from 402 to about 500 pages.
