iv. PREFACE 



To furnish a Flora containing practically all the 

 plants of a limited area that bloom during the spring 

 months is the aim of this little book. The area repre- 

 sented is that of the eastern edge of the Great Basin 

 as far south as Manti. Only those plants blooming by 

 June fifteenth have been included. 



Believing that an international botanical code is 

 preferable to one of local application, the writer has 

 endeavored to follow the rules of nomenclature 

 established by the Vienna Congress. 



This little book is prepared for the use of the 

 student who has no previous botanical training in the 

 use of a key and manual; hence the descriptions in 

 many cases have been made longer than would be 

 necessary for the trained botanist ; technical terms have 

 been used as sparingly as possible, and the keys are 

 correspondingly simple and often artificial. 



Because of the extremely divergent views held by 

 botanists today, both regarding nomenclature and 

 specific and generic limitations, the writer gives a 

 more extended synonomy than is usually thought 

 necessary for so limited a manual ; but it will be 

 found that an extensive list of synonyms is absolutely 

 required by the teacher who does not have access to 

 a fairly complete botanical library. In order that these 

 synonyms be in the most convenient place, they have 

 been put immediately after the accepted name of the 

 plant, instead of at the end of the description as is 

 usually done. 



In compiling this Manual, the writer has made use 

 of Britton & Brown's Illustrated Manual of the 

 Northern States and Canada; of both editions of 

 Coulter's Manual of Rocky Mountain Botany; of
