Jadwigia Moestrup, K.Lindberg & Daugbjerg, 2005
Holotype species: Jadwigia applanata Moestrup,K. Lindberg & Daugbjerg
Original publication and holotype designation: Lindberg, K., Moestrup, Ø & Daugbjerg, N. (2005). Studies on woloszynskioid dinoflagellates I: Woloszynskia coronata re-examined using light and electron microscopy and partial LSU rDNA sequences, with description of Tovellia gen. nov. and Jadwigia gen. nov. (Tovelliaceae fam. nov.). Phycologia 44: 416-440.
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.

Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
