Table I
Submaster Key to Tricolporate Grains

A4 Psilate and scabrate grains
These are tectate grains that are either smooth on the surface, 
psilate, or have a definite surface texturing of very small surface elements.
Table I1
Key to Tricolporate, Psilate, Scabrate Grains
A3 Echinate grains
Grains with well developed spines
Table I2
Key to Tricolporate, Echinate Grains
A2 Foveate and suprareticulate grains
Grains with either large depressions on the surface or with a patterned reticulation of muri, ridges, and lumens where the 
muri are not clearly composed of individual surface elements.
Table I3
Key to Tricolporate, Foveate, Suprareticulate Grains
A1 Intectate and per-reticulate grains
Grains with clearly defined surface elements more or less uniformly distributed on the surface or a patterned 
reticulation where the muri are composed of individual surface elements.
Table I4
Key to Intectate, Per-reticulate Grains
Note: It can be somewhat arbitrary to decide if a grain is scabrate or intectate if the surface elements are very small or if a grain is suprareticulate or per-reticulate. It may be necessary to run some grains through two tables for an identification.
