Molecular phylogenetics of Phyllanthaceae: evidence from plastid MATK and nuclear PHYC sequencesPollen morphology is of great significance in taxonomy, phylogeny, palaeobotany, aeropalynology and pollen allergy (Paul E. et al.,2014). Nine (9) species of the family Euphorbiaceae (Cnidoscolus laurifolia, Croton zambesicus, Euphorbia heterophylla, E. hirta, Ricinus cummunis, Mallotus oppositifolius, Microdesmis puberula, Acalypha ciliata, and A. wilkesiana) were studied palynologically to determine the morphological features and diversity as an aid in the classification of its members. Pollen analytical studies of these species showed a lot of variations in the types of apertures, shapes, sexine pattern, pollen size, colpi length and width. However, the variations above are generally reduced within species of the same genera. For instance, E. hirta and E. heterophylla were observed to have tricolporate (C 3 P 3) aperture type giving reason for them being in the same genus. Similar form and symmetry observed in all the species studied also were reason for them being in the same family. INTRODUCTION A brief resumé of the history of comparative pollen morphology and taxonomy may enable one to understand better today's philosophy and practice of the subject. The study of pollen is inevitably linked with the history of microscopy but is also associated with fashion. Comparative pollen morphology has been studied for about 150 years beginning with workers like Mohl (1835) and Hassell (1842). The subject was adopted by workers in the classical German school of plant taxonomy of the late 19th and early 20th century as for example the works of Hallier (1893) on Convolvulaceae and Urban (1916) on Bignoniaceae show. Lately two workers have made outstanding contributions in providing the foundation for the study of pollen morphology in relation to systematics. First, Wodehouse (1935), who provided the classical background to the importance of the study of the "whole" pollen grain. A view almost forgotten by a majority of workers until comparatively recently where it has been so strongly advocated by Dahl (1976) and followed by Muller (1979, 1981) and is now rapidly becoming the accepted approach. The second great worker is of course Erdtman (1952) who provided the work which is rightly regarded as the corner stone of modern comparative pollen morphology. Erdtman's work centred on the study of the acid-resistant sporopollenin exine. The shape, size, apertures, ornamentation and the stratification of the wall are the characters which proved so useful in distinguishing pollen grains of different species genera, tribes, families and orders. Treatment with acids, the acetolysis method, arose from the techniques used to prepare fossil pollen from the Quaternary and earlier epochs.
