La flora arvense tiene interés por su incidencia económica en los cultivos agrícolas y su aportación a la biodiversidad, un aspecto este último que se va incorporando al control de las malas hierbas. En este libro se describen e ilustran 138 especies de la flora de Navarra y las 35 familias a las que pertenecen; en el caso de 47 especies también se describen sus plántulas. Para facilitar su identificación se proporciona información sintética de los grandes grupos taxonómicos de flora vascular a los que pertenecen, morfología, ciclos vitales y formas biológicas. Estos aspectos son también útiles como una introducción a la práctica de la botánica, dada la amplia distribución de buena parte de las especies que integran la flora arvense.
