Carex geminata Schkuhr
The Type (in Herb. Botanische Anstalten der Universität, Halle (Saale), Germany) is a rather poor specimen with male, and some female, spikes missing, but the

utricles are fully mature, leaving no doubt as to its placing. The label reads as follows:
“C. Ternaria Forster. n.75 SK. von Prof. Sprengel d. 29. April. 98. hiervon Wunschte ich noch ein besseres Exemplar zu erhalten.”
and on the reverse side of the sheet:
“N. 75 Carex geminata SK. Carex ternaria Forster gepaartes Riedgrass.”
Schkuhr states (l.c. 1801, p. 65) that he received the specimen from Sprengel who sent it to him from the Forster Herbarium. The Type locality therefore would be either Dusky Sound or Queen Charlotte Sound.
A further specimen with male spikes was received by Schkuhr (ibid.) and illustrated on Tab. Pp. but this specimen is no longer in the herbarium at Halle (K. Werner, pers. comm.). Wahlenberg (Vet. Akad. Nya Handl. Stockholm 24: 160, 1803) apparently chose this second, more complete specimen as representing Schkuhr's species and his description applies to it only (“… capsulis ovatoglobosis cum acumine.”). Subsequently Willdenow (Sp. Plant. ed. 4, 4: 249, 1805) adopted Wahlenberg's view and described the utricles as “… subglobosis brevissimis rostratis …” His description is copied almost verbatim by Schkuhr (Nachtr. 28, 1806) and Steudel (Syn. Plant. Cyper. 206, 1855). The second specimen seems to be referable to C. lessoniana Steud.; that Forster collected both species is proved by the Type of C. geminata and a specimen of C. lessoniana in the Herbarium at Kew.
Therefore, the name C. geminata Schkuhr sens. str. must be applied to the original description and Tab. W. No. 75. Tab. Pp. and subsequent descriptions refer to the species now known as C. lessoniana Steudel. The synonymy is amended to:
C. geminata Schkuhr, Riedgr. 65, Tab. W, f. 75, 1801. excl. Tab. Pp.
Syn. C. confusa Hamlin, l.c. p. 58, Fig. 4, 1954 based on C. ternaria var. gracilis Cheeseman, Trans. N.Z. Inst. 16: 432, 1884.
I am deeply indebted to K. Werner, University of Halle, and Prof. Dr. R. Mansfeld, Gatersleben, for their help in clarifying this confusion.
