GENERAL INDEX. 



NUMBERS REFER TO PARAGRAPH, NOT TO PAGE. 



Botanical names must be looked for in their alphabetical place 

 in the body of the work. If not found there, look in the index for 

 the genus name which will be marked with an Asterisk (*) and see 

 whether the name does not occur elsewliere as a synonym. Thus 

 failing to find Atropa physalodes L. under Atropa, No. 219, look 

 for Atropa in the index, where there will be found references to 

 1274 and 1579. Under the latter you will find the name sought 

 given as a synonym of Physalodes physalodes (L. ) Brit., known 

 popularly as Apple of Peru or Peruvian Bluebell. 



Where the common name consists of a noun and adjective look 

 always for the noun, if that is properly a plant name, as Lily or 

 Rose. Otherwise you will find the name treated as a compound 

 word, e. g. Meadow-sweet, Old-man, to be looked for in their 

 alphabetical place in the index. 



Remember in this connection that all such names as Calisaya 

 bark, Spruce gum, Persian berries are treated as compound words; 

 do not look for Bark, Gum, Berries, but for Calisaya, Spruce, Per- 

 sian. 



Where the same popular name is applied to several species, that 

 which it most commonly designates is placed first, and where the 

 application of the name is unusual, the fact is indicated by aflBxing 

 to the reference a dagger (f). 



In the case of common genera such as Oak, Maple, Ash, a 

 general reference only is given to the genus in question, under 

 which the species sought can then be readily found. Thus, to find 

 Sugar Maple, look for Maple (species). The reference is to 16, 

 under which you will find that the name is applied especially to 

 Acer Saccbarum Marsh., but also to A. Negundo L. and to A. 

 nigrum Michx., the last distinguished, however, as Black Sugar 

 Maple. If you fail lo find a name in the index, turn always to the 

 body of the work, and see whether the name is not given there in 

 its alphabetical place as a genus name. 



German, French and Latin names are to be looked for in the 

 index, the noun usually standing first. Pharraacopoeial names are 

 not given in the index when they coincide with the botanical
