Type Information
Syntype localities: Ad Sachalien, Tilesius ; ad Kamtschatka, Chamisso; unde specimina communicaverunt.; (Agardh 1820: 219) Lectotype: Agardh’s (1820, pl. 13) illustration (epitype) (Powell 1957) Notes: Wynne (2010: 40) writes" Fucus evanescens was first described by C.Agardh (1820) based on a pair of syntype collections, one made by Tilesius at Sakhalin while on the 'Nadesda', the voyage
of 1803–1806 under the command of Adam Krusenstern, and the second collection
made at Kamchatka by Chamisso on the later Romanzof Expedition of 1815–1818
under the command of Otto von Kotzebue (Wynne 2009b). The following year,
(C.Agardh 1821, pl. XIII) depicted the Kamchatkan specimen collected by Chamisso.
Gardner (1922, pl. I, fig. 2) reproduced C. Agardh’s (1821) pl. XIII. Gardner
(1922: 52) stated that Setchell examined the type specimen of F. evanescens, No.
00299 in the Agardh Herbarium in Lund. Rice & Chapman (1985) examined that
specimen and concluded that it "bears little resemblance to C.Agardh’s illustration
(1821) and therefore is not a suitable lectotype." They concurred with Powell’s
(1957) earlier designation of the type of F. evanescens as C.Agardh’s illustration
(1821, pl. XIII)."
