| Abstract: | Peridinium limbatum (Stokes) Lemmerman reproduces sexually in nitrogen deficient medium. Sexual reproduction is homothallic and similar to that reported for other Peridinium species. Thecate planozygotes of P. limbatum and P. cinctum enlarge greatly. Suture bands connecting thecal plates enlarge unequally in P. cinctum producing a “warty” zygote and equally in P. limbatum maintaining the regular but enlarged appearance of the cell. Zygotes can be recognized by greatly enlarged striated suture bands. |
