Eragrostis species of Zimbabwe

Les graminees sont assez difficiles a identifier sur le terrain et certains genres, comme Eragrostis, comptent de nombreuses especes difficiles a distinguer. Ce livre fournit des informations pratiques qui faciliteront la reconnaissance de ces especes. Destine aux botanistes, ecologues, agronomes, gestionnaires de la nature, etudiants et techniciens, il servira aussi de reference aux eleveurs impliques dans la gestion de la faune sauvage. Enfin, il contribue a la connaissance de la biodiversite vegetale des ecosystemes d'Afrique tropicale.Table of contents: Preface. Thanks. Principal abbreviations used. Part I - Introduction.
