Family Lyrellaceae Mann

Lyrella clavata (Gregory) D.G.Mann (Pl. 9, Fig. 5) References: Hustedt 1961 -66, p. 444, figs 1509a-c; Desikachary & Prema (1987, pl. 300, fig. 1) (both as Navicula clavata Gregory); Witkowski et al. 2000, p. 231, pl. 97, fig. 6.

Features: Apical axis: 45-60 µm, transapical axis: 20-30 µm, striae 16-18 in 10 µm. Valves elliptic with produced rostrate apices. Raphe straight, axial area narrow; central area transversely extended. Lateral hyaline areas broad in the middle of the valve, narrowing towards apices and terminating at either side of the base of the apex, slightly deflected to the sides.

Remarks: Striae density is slightly higher than those given elsewhere (10-14 in 10 µm).

Widespread marine species.
