Summary
The morphogenesis of the different types of labiate processes is compared among three species of centric diatoms [Stephanopyxis turns (Greville) Ralfs,Odontella sinensis (Greville) Grunow, andOdontella aurita (Lyngbye) Agardh]. In all species, a cytoplasmic structure,i.e., the labiate process apparatus, situated close to the develo** labiate process, appears before the labiate process begins to form and disappears upon its maturation. The possibility that the labiate process apparatus is implicated in the phylogeny of the labiate process is discussed.
