Motility  
Specialized structures This nonbranching, filamentous cyanobacterium is unique in that the short trichomes in cross-section are triradiate (Lang 1977). The trichomes are straight to helically twisted, about 15 um in diameter. The cells are short (1-2 um). The triradiate form usually has broad, armlike projections 120` apart, separated by U-shaped depressions The pigmentation is concentrated in the arms. A thin sheath (3 um thick) covers the trichome. Cross-walls are as in the genus Oscillatoria, with an invagination of the peptidoglycan layer but not of the outer LPP envelope. The relatively thick peptidoglycan layer of longitudinal walls is characterized by evenly distributed pits 70 nm in diameter, as in some species of Oscillatoria, eg. O. princeps (Halfen and Castenholz, 1971; Guglielmi and Cohen-Bazine 1982b
