190 THE NOMENCLATURE OF ARENARIA ULIGINOSA. 



Sornborger'.s specimens correspond exactly with those from the 

 Old World. The nature of the occurrence in Labrador, together 

 with the presence of the species in Greenland, leaves little doubt as 

 to the indigenous character of the Labrador specimens. 



This species has a rather complicated synonymy, which has led 

 to so much confusion that it will be best to cite its bibliography 

 here in some detail. Its names have been as follows : — • 



Sperqula stricta Swartz, Vet. Acad. Handl. Stockh. 20, 229 

 (1799) ;' and in Schrad. Journ. 1800^ 256. 



Arenarid nliijinosa Schleicher, *' Cent. exs. 1, n. 47," ace. to 

 Lam. & DO. Fl. Fr. iv. 786 (1805), where a good description is 

 given; DC. Ic. PL Gal. Rar. 14 (excl. syn. in part), pi. 46 ; and 

 Prodr. i. 407 ; Hook. f. Arct. Pi. 287, 322 ; Gray, Proc. Acad. 

 Philad. 1863, 58 ; Hook. f. Stud. Fl. Brit. Is. ed. 3, 63 ; Britton, 

 Mem. Torr. Club, ii. 37. 



Alsine stricta Wahlenberg, Fl. Lapponica, 127 (1812) ; Fl. Dan. 

 pi. 2962; Nyman, Conspect. 118; and continental authors generally. 



Arenaria lapponica Spreng. Syst. ii. 402 (1825) ; Hook. f. & 

 Jacks. Ind. Kew. i. 179. 



Sabidina stricta Reichenb. Fl. Germ. Excurs. 789 (1839). 



Stellaria stricta Sw. ex Steudel, Nomencl. ed. 2, ii. 637 (1841). 



Arenaria stricta Wats. Bibliog. Index, 98 (1878), at least as to 

 the first three synonyms. 



From the above synonymy it is evident that there is a con- 

 siderable choice of names, and that the selection by different authors 

 is likely to vary somewhat according to individual ideas of classifi- 

 cation and nomenclature. It is clear, however, that those who 

 unite Alsine and Arenaria and who also prefer the " first correct 

 combination" must choose Arenaria ulirjinosa, the name current in 

 England, It is to be regretted that the statements made in regard 

 to this species in the Index Kewensis are most conflicting and in- 

 accurate, being as follows : — 



Under Alsine 



A. stricta Mert. & Koch, in Roehl. Deutschl. Fl. iii. 278 



= Ar. stricta. 

 A. stricta Wahlenb. Fl. Lapp. 127 = Ar. lapponica. 

 Under Areyiaria 



A. lapponica Spreng. Syst. ii. 402. — Lappon. (given as a 



valid species of restricted range). 

 A. ulifjinosa Schleich. ex Schlecht. in Ges. Naturf. Fr. 

 Berl. Mag. vii. (1813) 207 = Arenaria stricta. 

 Under Sabidina 



S. stricta Reichenb. Fl. Germ. Excurs. 789 = Arenaria 

 stricta. 

 Under Spergula 



S. stricta Sw. in Vet. Acad. Handl. Stockh. xx. (1799) 

 229 = Arenaria stricta. 



Now of these six clear references to this well-known European 

 plant all are incorrect. Four refer it to Arenaria stricta, but the
