Fig. 2 in Morphological and molecular variability of Peridinium volzii Lemmerm. (Peridiniaceae, Dinophyceae) and its relevance for infraspecific taxonomy
Fig. 2 Box plots displaying correlations between cell size (of motile cells; A, B) or side length (of empty thecate cells; C) in selected strains. Colours correspond to the ribotype of each strain (blue: ribotype I; magenta: ribotype II; orange: ribotype III). Statistically significant clusters are indicated with letters a, b and c and were calculated with Tukey's Honest Significant Difference (HSD) test (p-values <0.05). Box plots depict percentile values from 25–75% (box), median (bar inside the box), standard deviation (whiskers) and outliers (dots)

David D. Keck's annotations of taxa here included in Poasecunda : Explanation note: The following taxa recognised by Keck, but included by us in P.secunda s.l., are given in the specimen annotation lists: P.ampla, P.canbyi, P.gracillima, P.incurva, P.juncifolia, P.nevadensis, P.sandbergii and P.scabrella. His lists focused on western Continental United States species but included some mainly non-arctic Alaskan, Canadian and Mexican (Baja California) records and some records of eastern United States species. Copies of the original typed lists are stored in the reprint files in the Grass Lab in the Department of Botany, Smithsonian Institution. Optical character recognition (OCR) was performed on the present selection to allow the lists to be searchable to a large degree. Keck's annotations are considered to be sound and to represent hundreds of historical collections widely distributed in herbaria as vouchers for P.secunda infraspecies. We treat P.ampla, P.juncifolia and P.nevadensis as varieties of P.secundasubsp.juncifolia (vars. ampla, juncifolia and nevadensis, respectively) in our revised classification. The remaining taxa are treated as varieties of P.secundasubsp.secunda , as follows: var. gracillima (P.gracillima), var. scabrella (P.scabrella) and var. secunda (P.canbyi, P.incurva, and P.sandbergii).
