INTRODUCTION 



It is the purpose of this bulletin to give an 'account of investi- 

 gations of a botanic nature pertaining more or less directly to 

 the flora of Texas and adjoining territory. The information 

 has been gathered from numerous sources — botanical journals, 

 government publications, etc. — that are not generally available 

 to the teacher and student. An annotated list of publications 

 on the botany of Texas has been prepared for the aid of teachers 

 of botany, and is appended hereto.
