Table C
Key to Bilaterally Symmetrical Grains and Spores

A2 Grains with collumellae in their walls, with a single sulcus running most of the length of the grain as an aperture






B2 Grains with slight surface texturing, sulcus very narrow, grains appear pointed at one end in most orientations, 42 μM in longest dimension

Sabal
