1900. No.8. VASCULAR PLANTS COLLECTED IN ARCTIC NORTH AMERICA. 23 
52. Saxifraga stellaris L., Sp. pl., 1753, p.400; S. stellaris v. comosa 
Porr.; Macoun, Catalogue I, 1883, p. 153; S. foliolosa R. Br.; Hooker, 
Fl. Bor. Am., I, 1834, p. 251; Spatularia foliolosa (R. Br.) Smart, N. Am. 
Flora, 1905, p. 149. 
A single specimen of the bulbiferous flower-less form (var. comosa 
Rerz., Fl. Scand. Prodr. 1779, p. 79) has been collected on Aug. Ist, 1904. 
53. Saxifraga hirculus L., Sp. pl., 1753, p. 402; Hooker, Fl. Bor. 
Am., I, 1834, p. 252; Macoun, Catalogue I, 1883, p. 154; Leptasea hirculus 
(L.) Smarz, N. Am. Flora, 1905, p. 152. 
Rar, Wollaston-Victoria Land. — Watker, Boothia Felix. 
In full bloom in the beginning of August (1st—1oth in 1904, 3rd in 
1905) and with empty capsules from the foregoing year. 
The numerous specimens collected coincide fully with the description 
of var. propinqua (R. Br.) Simmons, Sec. Arct. Exp. Fram, 1898—1902, 
No. 2, 1906, p. 65. I follow H. G. Simmons (l.c.) in upholding the 
Arctic American S. hirculus as a special variety, and I think he is quite 
right in using the name S. propinqua R. Br. (cf. S. hirculus, 8, R. Brown, 
Chloris Melvill., 1823, p. 15) instead of var. alpina ENGLER (Monogr. 
Saxifraga, 1872, p. 124) which is an alpine Himalayan variety. 
54. Saxifraga tricuspidata ROTrBÜLL, Skr. Kiöbenh., Selsk. Lærd. & 
Vidensk., vol. 10, Kiöbenhavn, 1770, p. 446, tab.6, fig.21; Hooker, Fl. Bor. 
Am., I, 1834, p. 254; Macoun, Catalogue I, 1883, p. 154; Leptasea tri- 
cuspidata (RETZ.) Haw.; SMALL, N. Am. Flora, 1905, p. 154. 
Rae, Wollaston-Victoria Land. — WALKER, Boothia Felix. 
In full flower in the last days of July (31st) and the beginning of 
August 1904 (1st—6th). 
The specimens collected show a tendency to reduce the lateral teeth, 
thus forming a transition to f. subintegrifolia ABROMEIT, Bibl. botan., 
Heft 42, 1899, p. 36. 
It is remarkable that the American authors again and again (e. g., 
Britton & Browy, Ill. Fl. U. S., Il, p. 172 and SMALL I. c.) quote RETzIUs, 
Prodr. Fl. Scand., ed. 2, 1795, p. 104 for this exclusively American species 
described by RoTTBöLt (1. c.) in 1770. 
Onagrariaceae. 
Epilobium L. 
55. Epilobium latifolium L., Sp. pl., 1753, p. 347; Hooker, Fl. Bor. 
Am., I, 1834, p. 205; Macon, Catalogue I, 1883, p. 169.
