Cocconeis ornata W. Gregory Figs 22–26

Ref. illus.: Gregory 1857, pl. IX (1), fig. 24; Peragallo & Peragallo 1897 –1908, pl. 4, figs 13–15; Montgomery 1978, pl. 61, figs A–D; Riaux-Gobin et al. 2014, figs 9–14

Samples: GU44AU-2

Dimensions: Length 19 µm, width 15 µm, striae ca 10 in 10 µm

Diagnostics: SV: striae coarsely uniseriate but sometimes branching towards the margin, striae interrupted by a longitudinal hyaline line; margin with parallel rows of papillae. RV not seen.

Comments: A few specimens in this sample. Gregory (1857) was charmed by the “rich ornate aspect” of this “beautiful” species, which does indeed appear ornate, especially in SEM ( Fig. 27). The original drawing did not do it justice.
