    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1986) Baño Breis, Francisco del; Facultad de Biología
    A dichotomic key for the identification of one hundred of genera and families of tricolpate pollen is proposed. The generic key is accesible through an entry key which selects the main types of pollinic sculptures and refers to the corresponding groups. In the preliminary sections of the entry key. the principal types of exin are described. Some general reflexions on pollinic morphology are given.
