Comment
Note that the sexine sometimes consists of 5 layers, but of those, 3 layers are the most common (sexine 1 = columellae; sexine 2 = tectum; sexine 3 = sculpture elements). Sexine is distinguished on purely morphological criteria; compare with 'ectexine ; GO:0043669'. See also 'nexine ; GO:0043672'.
