Nomenclatural notes
Named for Jadwiga Woloszynska. - (17 Mar 2010) - M.D. Guiry

Description: Cells covered with many, often hexagonal, amphiesmal plates which are usually difficult to see in the light microscope except after staining or in empty thecae. Anterior end with straight or slightly curved apical line of plates (ALP) that extends from the ventral to the dorsal side of the cell. The ALP is lined on each side by a row of pentagonal amphiesmal vesicles. Several or many golden-green or brown chloroplasts in the periphery of the cell. Hypnozygotes smooth, round. Only the type species, Jadwigia applanata, has been examined in detail. Three additional species are included here pending further studies. Three of the four species are known to possess an eyespot, whereas an eyespot has not been reported in J. hiemalis.

Numbers of names and species: There are 4 species names in the database at present, of which 4 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
