 Drottningholm, Kanso, 01, Lagekwall and Tiselius (hb. Stockholm.), f. ferfoliaii- 

 folius; Varmdon at Rorsundsvik, 94, Tiselius (hb. Stockholm., Uppsal.), f. exiensus; 

 Tranebergsbro, 52, Thedeisiius etc. (hb. Stockholm.), f. typicus; Vinterviken, 41,

 ScHLEGEL (hb. Stockholm.), f. fnaritimus; Varmdo, Ekudden 87 (hb. Stockholm., 

 Uppsal.), f. maritimus, labelled >P. gramineus X perfoliatus (B At i Hn. ed. 12. c. fr. » 

 Almqttist scrips.; Varmdo, Ekudden in palude, Tiselius (hb. UppsaL, Lund.), f. 

 vadosus; Jarlasjon, Bjoenstrom (hb. Uppsal.), f. typicus; Hammarbysjon, V. B — M 

 (hb. Uppsal.); Rivulet between Ronninge Lake and Stora Vartan, 01, Jakobsson 

 (hb. Stockholm.), f. suhovalis. — Upland, Signildsberg, 1803 (hb. Uppsal.), f. inter- 

 medius; Gottsunda, 50, Floderus (hb. Uppsal.), f. fyrisensis; Sigtuna, 82, Flodebus 

 (hb. Uppsal.), f. typicus; Norrtelje in the river, 84, Hbdlund and others (hb. Stock- 

 holm., Uppsal, Lund.), f. typicus; Frotuna, 80, Hedlund and others (hb. Stock- 

 holm., Uppsal), f. robustior; Frotuna, lake, 67, Thedenius (hb. Stockholm.), f. ty- 

 picus, probably the same cross as the foregoing; Upsala in the Fyris at Ensta and 

 other localities, Wahlenbeeg and others (hb. Stockholm., Uppsal, Lund., Gothenb.), 

 f. fyrisensis; Ensta, 82, Tiselius (hb. Stockholm., Uppsal, Lund., Gothenb.), f. iimo- 

 minatus; Ensta in the Fyris, 87, Almquist (hb. Stockholm.), f, perfoliatifolius, lab. »P. 

 gramineus X perfoliatus |3 i Hn. ed. 12 » Almquist scrips. Another specimen from 

 the same station is labelled »P. gramin. X perfol. a», but is evidently the same cross- 

 ing, which now approaches to P. perfoliatus and must be classed together with p 

 subperfoliatus, now approaches more to the other parent species and must be refer- 

 red to Y suhinterinedius (f. fyrisensis, f. typicus and f. intermedius). This is an evid- 

 ent instance that one and the same crossing sometimes exhibits a considerable 

 varying faculty. F. innominatus from Ensta, however, is after all a separate cross.

 ing; Fasterna in Ranas river, 82, Tiselius (hb. Uppsal, Lund.), f. robustior partly
