The aim of this investigation is dealing with determination
of pollen micro- and macro-morphological characters of
Egyptian taxa of subclass Archichlamydeae to provide
palynological information and an identification key adapted
for use with archeobotanical materials. The pollen of 41
Egyptian taxa belongs to 18 families representing the current
vegetation of Faiyum area described and illustrated with both
LM and SEM micrographs. On the basis of pollen units,
number and type of apertures, exine patterns were great
diagnostic significance among the examined taxa. Seven
major pollen types and 18 subtypes included in two groups
(complex and single pollen groups) were recognized. Pollen
types: Polyads, triporate, tetra- hexaporate and
pantobrevicolpate are characterized to Mimosoideae,
Urticaceae, Fumariaceae and Portulacaceae respectively;
while pantoporate, tricolpate and tricolporate pollen types
show highly diversity in pollen characters, comprising 16
pollen subtypes distributed among 14 families. A description,
illustriation in the form of scanning electron micrographs and
a key for identification of the different taxa is provided.
