    Description / Table of Contents: Riassunto Nell'ambito di uno studio sulle Pinophyta ornamentali vengono presentate le schede palinologiche diThuja orientalis L. e diCryptomeria japonica (L. fil) D. Don. Sono stati effettuati anche confronti su pollini provenienti da una località dell'areale originario delle due specie. InCryptomeria japonica (L. fil.) D. Don i valori di DV, D01, D02, esina, diametro maggiore, diametro minore, calcolati sul campione giapponese, risultano significativamente diversi da quelli dei campioni italiani; perThuja orientalis L. non si registrano differenze significative. Per entrambe le specie i pollini delle due località italiane non mostrano differenze significative né per forma né per dimensioni. È stato effettuato un confronto fra gli effetti dell'acetolisi secondo Erdtman (1960) e la tecnica acetolitica secondo Tatzreiter (1985); i risultati morfometrici sono sovrapponibili per entrambe le specie.
    Notes: Summary The morphopalynological cards ofThuja orientalis L. and ofCryptomeria japonica (L. fil.) D. Don were illustrated as part of a more comprehensive study on ornamental Pinophyta. Pollens from the original area of the two species were also compared with grains coming from plants cultivated in Italy. In the case ofCryptomeria japonica (L. fil.) D. Don DV, D01, D02, exine, min. and max. diameters, calculated on a japanese sample, differed significatively from the italian sample. In the case ofThuja orientalis L. no significant differences were observed. Pollen from the two italian sites did not show significative differences in size and shape. Pollens acetolysed with the traditional method (Erdtman, 1960) were compared with pollens treated with the Tatzreiter method (1985). Morphometric analysis showed similar values for both species.
