Palynotaconomic studies in Tabernaemontane L. sensu lato (Apocynaceae)

Abstract

Abstract The pollen grains of some genera related to Tabernaemontana (Apocynaceae) were examined by means of light and electron microscopy. Some genera ought to be included in Tabernaemontana with reference to the general pollen morphology as well as to the fine sculpture of the inner exine surface. Quelques genres d'Apocynaceae proches de Tabernaemontana ont ete examines en Mph et MeB. On suggere qu'un certain nombre de genres allies soient inclus dans le genre Tabernaemontana a la suite de l'examen du pollen et notamment de la face interne de l'exine.
