Excerpt from Contributions From the United States National Herbarium, Vol. 2

The purpose of this manual is to bring together and make easily ao cessible our scattered information concerniu g the flora of western Texas. It will be considered a mark of appreciation if all omissions or mistakes be reported to the writer. The present work being necessarily a com pilation, many recorded facts have doubtless escaped notice, and some Species may have been admitted which do not fairly come within the limits chosen. It is intended to include all Texan plants west of the ninety-seventh meridian. The desirability of presenting this manual in parts has prevented the arrangement of the orders in a sequence more in accordance with our present knowledge of their affinities. N o attempt has been made to give synonymy, except when necessary to a clear understanding of the species under consideration. It should be stated further that the work has been prepared not merely as a con venient reference book for botanists, but also as a handbook for Texan students. The latter purpose explains the introduction of analytical keys and of local names and uses, together with the simplicity ofdescrip tion, which would not have been necessary for the professional botanist. In the third part of the work it was thought best to conform as far as possible to the rules of nomenclature adopted by American botanists at the Rochester meeting of the American Association for the Advance ment of Science in 1892, although doubtless not all the required changes have been made. In this work Dr. Ehnon M. Fisher has ren dered great assistance. Mr. Frederick V. Coville has prepared the manuscript of the J uncaceze, Prof. L. H. Bailey the genus Carex, Mr. L. H. Dewey the Gramineae, and Prof. L. M. Underwood the Pterido phyta. The metric system of measurements is followed throughout the work, and to those not accustomed to its use the following table, in addition to that given on page 5, may be helpful.
