Cryptomonas curvata, Ehrenberg , 1831
Synonyms
  • Cryptomonas rostratiformis : Skuja (1956)
  • Cryptomonas rostrata : O.V.Troitzkaja (1922)
  • Cryptomonas reflexa : M.Marsson, Skuja (1939)
  • Cryptomonas lilloensis : Kufferath (1954), W.Conrad
Morphological Characteristics

Sigmoid-shaped cells with a characteristic recurved posterior, anterior rostrate. The furrow is curved slightly toward the left, and the vestibular ligule is pointed and attached to the left side of the vestibulum. Cells contain two chloroplasts, two pyrenoids and nucleomorphs, the later are located posterior to the pyrenoids and anterior to the nucleus.
