| Comments | Entry is from Chase (1907) index: "Protonema Meneghini, 1844. (Protonema) thermale Men.- Pedicino - p. 7I, f. 35-36 (Denticula elegans, var. valida)." We were not able to verify Meneghini's work. Current internet version of the ING lists only Protonema Agardh 1824, p. 43 (ref. 000102), as a plant. |
