| Inhoud: |
Hemiselmis rufescens Parke and three species of the genus Chroomonas have been examined by electron microscopy. They demonstrate certain characteristic features of the Cryptophyceae, such as the presence of trichocysts and the arrangement of thylakoids in pairs in the plastid. The prominent pyrenoid of the genus Chroomonas is penetrated longitudinally by a tongue of cytoplasmic matrix which originates from between the two pairs of plastid membranes. In the genus Hemiselmis, however, the pyrenoid is traversed by a pair of thylakoids. The nucleus, Golgi apparatus and Corps de Maupas also occupy characteristic positions. These features indicate a close relationship between these two genera and the other major genus Cryptomonas, and support the suggestion that the Cryptophyceae is a discrete taxonomic group. |
