In the past issues, only the pollen morphology of the dicotyledonous plants was reported. This time, the pollen morphology of monocotyledonous plants is also included, namely, 23 families, comprising of 147 genera and 282 species of dicotyledons, and 21 families comprising of 88 genera and 147 species of monocotyledons are described. The signs, A, B, C, D, E, F, and G in 70 plates are to designate.; A, equatorial view; B, polar view; C, exine stratification ; D, sexine pattern; E, grains without definite view; F, tetrads; and G, polyads. The shape of grains is usually expressed by the ratio between polar axis and equatorial axis (P/E) or outline of grains, and the size of grains is often shown as polar axis times equatorial ax is (P×E) as proposed by Erdtman (1952). But the pollen size of monocotyledonous plants is expressed slightly differently from that of dicotyledons. |
