Notes:
Khawkinea quartana, a naturally occurring colorless homologue of Euglena, was examined with the electron microscope. The organism is biflagellate though only one of the 2 flagella emerges from the anterior reservoir. The pellicular strips covering the body of the organism are supported by microtubules which are continuous in part with microtubules bordering the reservoir. Additional rows of microtubules are found associated with the kinetosomes. An eyespot is located in the wall of the reservoir and, adjacent to it, the contractile vacuole.The nucleus, mitochondria, and Golgi complexes are similar to those described in other euglenoid flagellates. The food reserve is paramylon.The study supports the phylogenetic origin of Khawkinea from pigmented Euglena through the loss of chloroplasts.
