Palatability applies to the growing season of the vegetation in which the 

 species in question occurs and, in some cases, to the yearlong season. The 

 following palatability tabulation has been followed in this work: 



Percent Percent 



Practically worthless 5 Good 55 to 70 



Poor 5 to 15 Very good 75 to 85 



Fair 20 to 35 Excellent DO and over 



Fairly good 40 to 50 



There are numerous available records to the effect that species are grazed 

 in greater degree than that shown in this handbook. Where investigation has 

 shown that such records indicate overgrazing, they have been ignored or 

 properly discounted. 



Nomenclature 



The scientific (Latin) nomenclature adopted is in accordance with that used 

 in the Bureau of Plant Industry, U. S. Department of Agriculture. Readers 

 who seek an introduction to Latin plant nomenclature should consult such 

 works as Hitchcock's Descriptive Systematic Botany (1925), Swingle's A 

 Textbook of Systematic Botany (1928), and Pool's Flowers and Flowering 

 Plants (1929). Synonymous names are shown only so far as usage in the 

 common western manuals is concerned. Latin plant names in quotation 

 marks, followed by the phrase "not ", indicate that the 



Name of author 

 name is valid but misapplied to the plant under discussion. 



There are obvious advantages in having the English nomenclature of im- 

 portant plants standardized, so far as that is now feasible. In this work the 

 standard authorities of the Department of Agriculture have been consulted, 

 namely, Sudworth's Check List of the Forest Trees of the United States, 

 Their Names and Ranges; Standardized Plant Names, and the list of 

 preferred plant names spellings in the Style Manual of the Government 

 Printing Office. Some of the plants discussed in this publication have had 

 no well-established or acceptable English name; this work attempts to correct 

 that situation, and several new English plant names appear here for the first 

 time in print. 



Pronunciation 



An attempt has been made in these articles to assist the reader in the 

 pronunciation of scientific plant names by the insertion of accent marks. 

 An excellent discussion of this subject, in simple language, appears in a book 

 by Prof. L. H. Bailey* in the section Pronunciation (pp. 132-136, of the 

 chapter entitled "The Names and the Words", op. oit.). 



Broadly speaking, there is no single standard way of pronouncing scientific 

 plant names. There are two general methods of pronouncing such names in 

 this country : The English, and the continental European methods. The latter 

 method (which attempts to restore, insofar as is possible, the original Latin 

 pronunciation) has more world-wide use and is adopted here. There are three 

 main rules of Latin pronunciation: (1) Words of two syllables are accented 

 on the first syllable, thus: Lo'ttis, Phle'tim, Pl'nus, Ro'sa, Ru'bus; (2) Words 

 of more than two syllables are accented on the next to the last syllable 

 (penult) if that is long, thus: BalsamorM'za, Ciau'ta, Solidci'go, Zyyade'nus; 

 (3) The accent falls on the third syllable from the last (antepenult) if the 

 penult is short, thus: Amelan'cM-er, E'phe-dra, Juni'pe-rus, Paeo'nl-a. Notes 

 on Latin vowel quantities are available in any Latin grammar.
