Porella pinnataLinnaeus, Species Plantarum2: 1106. 1753.
"Habitat in Pensylvania." RCN: 7985.
Lectotype(Howe in Jarvis & al., Regnum Veg.127: 78. 1993): [icon] " Porellapinnis obtusis"in Dillenius, Hist. Musc.: 459, t. 68, f. "Porella". 1741. - Voucher: Herb. Dillenius ( OXF).
Generitypeof PorellaLinnaeus.
Note:After an extensive discussion, Howe (in Bull. Toney Bot. Club24: 518. 1897) treated the Dillenian material (OXF) associated with the cited Dillenius figure as the type of this name, followed in this by others such as Evans (in Rhodora18: 82. 1916) and Grolle (in Feddes Repert.87: 221. 1976). However, Linnaeus did not study Dillenius'material and would have based his own account on Dillenius'published description and illustration (Linnaeus wrote "Hanc neque ego vidi"). For this reason, Jarvis & al. designated the published illustration as the type, with the material as the typotype(while attributing the choice to Howe).
