Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Farinacci & Howe Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly compiled on this site. The "Catalogue of Calcareous Nannofossils" was originally compiled by Prof A. Farinacci 1969-1989, since 2000 it has been updated and extended by Richard Howe - see The Farinacci and Howe Catalog - an Introduction.

Original Description

Sedentary cells forming palmelloid colonies, kneecap-shaped, 6-9 µm diam., often flattened if touching each other. Chloroplast single, parietal, yellow-green, without stigma, with two large lobes and a protruding pyrenoid. Nucleus excentrically positioned. Golgi body single. Deposits of lipid, paramylon and polyphosphate. Motile cells elongate, 6-9 x 3-4 µm. Two unequal flagella, 13 µm and 5 µm, and a short slender haptonema inserted at some distance from the anterior end of the cell body. System of flagellar roots with several roots near the nucleus and eight parallel microtubules running away from the nucleus. Pit with lateral inflations entering the interior of the cell near the flagellar insertion.

Extra details from original publication
The organism differs from all Pavlova species that are examined in the electron microscope, in lacking the characteristic dense particles on the long flagellum. In other respects the external flagellar apparatus is typically Pavlova-like (Green & Manton 1970. Green 1973, Billard 1975, van der Veer 1976). The absence of minute dense particles on the surface of the cellbody is shared with P. virescens (Billard 1975) and P. calceolata (van der Veer 1976).
