Description
Cells with rhinote anterior. Vestibulum located about one third of the cell length from the apex; tubular gullet posterior. Periplast with internal and external hexagonal plates elevated anteriorly to accomodate underlying ejectisomes . Internal plates attached peripherally and posteriorly. The surface plates composed of short rod-like fibrils in a crystalline arrangement with coalescent borders . The periplastidial compartment has a single chloroplast with a single pyrenoid lacking traversing thylakoids and a nucleomorph in a periplastidial cytoplasmic evagination into the pyrenoid. Cells red ; chloroplast with C r - phycoerythrin 545. Marine (Hill and Wetherbee, 1988; Novarino , 1991 ). DA F periplast plates; (C) chloroplast; (E) ejectisome ; (F) flagellum ; (Fu) furrow ; (IPS) inner periplast sheet ; (N) nucleus; (Nu) nucleomorph ; (P) pyrenoid; (V) vestibulum . Scale=1 ~m.
