Wollea ambigua (C.B.Rao) R.Y. Singh (1942) Fig. 54 A–C View FIGURE 54 .

Basionym: Anabaena ambigua C.B.Rao (1937: 101)

Filaments solitary or several together in a parallel arrangement, enclosed in a firm, hyaline mucilaginous sheath up to 50 μm wide. Trichomes straight or flexuous, clearly constricted at the cross walls, ± narrowed towards the ends. Vegetative cells shortly barrel-shaped, 3.5–5.0 μm long × 4.5–7.0 μm wide; apical cells rounded. Heterocytes intercalary, spherical to slightly oval, solitary, 6.5–9.0 μm in diameter. Akinetes elongate-ellipsoidal, adjacent to the heterocytes, 13.0–16.5 μm long × 7.5–11.0 μm wide.

Specimens examined:—Balonne R. at St George, Balonne Minor R. at Cubbie, Bokhara R. near Kirrima, Condamine R. at Elbow Valley, Coopers Ck Tanbar Waterhole at Tanbar, Maranoa R. at Cashmere, Thomson R. Top Waterhole at Noonbah.

Observations:—Growing amongst other algae and aquatic macrophytes in the shallows and littoral areas of lowland rivers and associated waterholes.
