1.5.2 Terminology
Amb; (Ambitus) Erdtman (1952): Outline of spore or pollen grain in polar view.
Apices; The three areas close to the furthest point from the poles in triangular
spores.
Brochus–brochi; Erdtman (1952): Mesh of a reticulum, consisting of a lumen
and half the muri.
Cavate; Harris (1955): Separation of exine layers to form a cavity or cavities.
Cappa; (cap) Erdtman (1957): In saccate pollen the exine on proximal face of
corpus.
Cappula; Erdtman (1957): In saccate pollen, the relatively thin area of exine
between sacci roots and distal face.
Cingulum; Potonie and Kremp (1955): An equatorial thickening of the exine in
spores.
Commissure; Harris (1955): The line of dehiscence of tetrad scar.
Corpus; Erdtman (1957): The ‘body’ of a saccate pollen.
Distal face; Erdtman (1952): The face of the spore directed outward in the tetrad,
opposite the tetrad mark.
Exine; Erdtman (1952): The main outer, usually resistant layer of the spore or
pollen.
Ektexine, sexine; Erdtman (1957): The outer layer of the exine (pollen/spore
wall).
Granulate; Potonie and Kremp (1955): Sculptural elements that are more or less
round in surface view, and more or less round in side view.
Endexine, nexine; Erdtman (1957): The inner, usually un-sculptured layer of the
exine; may be structures.
Laesura-laesurae; Erdtman (1952): The rays of a tri-radiate tetrad scar or the ray
of a monolete scar.
Muri; Erdtman (1957): The walls or elevated areas bordering the spaces in a
reticulate pattern.
Pilate–pila; Potonie and Kremp (1952): Sculptured elements consisting of a
thickened apex and a narrow rod-like neck.
Proximal face; Erdtman (1952): That part of the spore or pollen grain which was
directed inward in the tetrad.
Punctate; Erdtman (1952): Minute perforation in the exine.
Reticulate; Erdtman (1952): Sculptural pattern consisting of brochi separated by
muri.
Rugulate; Couper (1958): Wrinkled elements irregularly distributed seen as broad
rounded crests and troughs in side view and long and narrow in surface view.
Saccus–sacci; Erdtman (1957): The air sac/sacs in saccate pollen grains which is
formed by the detachment of the exine layers.
Sculpture; Potonie and Kremp (1955): Elements forming a relief on the surface
of the spore or pollen grain and observed in the outline of the spore.
