Pollen morphology of 18 species of the family Caprifoliaceae from
Pakistan has been examined by light and scanning electron microscope.
Pollen grains are usually radially symmetrical, isopolar, oblate-spheroidal
to prolate-spheroidal rarely sub-prolate or sub-oblate. Sexine slightly
thicker or thinner than nexine. Tectum mostly spinulose to coarsely
reticulate or sub-psilate often rugulate-striate. On the basis of exine
pattern six distinct pollen types are recognized viz., Abelia
triflora-type, Lonicera
myrtillus-type,
Lonicera obovata-type,
Lonicera quinquelocularis, Lonicera
webbiana-type
