Abstract: | The use of the central raphe endings as a key character in the classification ofNitzschia is argued to be of doubtful validity. Some aspects of the evolution of the raphe are discussed in relation to variation in raphe structure within fibulate genera.Notes for a monograph of theBacillariaceae (Bacillariophyta) 1. |
