30. Alsine arctica (STEVEN) FENZL, |. c.; Arenaria arctica STEVEN in 
D.C. Prodr. I, 1824, p. 404; Hooker, Fl. Bor. Am., I, 1830, p. 100, 
excl. varr. Å ety, tab: 34, À (vix B). (See pl. I, fig. 2.) 
King Point. Flowering specimen, collected in the beginning of 
July, 1906 (GODFRED HANSEN). 
As to the distinguishing marks between this species and A. macro- 
carpa from which it is fairly distinct, see above. The specimens collected 
belong to REGEL’s var. scapigera (Pl. Raddeanæ, I, 2, p. 347) and are 
glandular-pubescent both on flower stalks and leaves; the ripe capsules 
from the year before are ca. 1!/, times as long as the sepals, petals nearly 
twice as long. Seeds brown, rough. 
Stellaria L. 
31. Stellaria longipes GOLDIE, Edinb. Phil. Journ., 6, 1822, p. 327; 
S. longipes and S. Edwardsii Hoox, Fl. Bor. Am., I, p. 95—96, 1830. 
PuLten’s list, Point Barrow to Mackenzie River, Richard's Isl. 
King Point. Flowering in the first days of July (6th—18th), 1906. 
The specimens differ from the typical form in the flowers being always 
solitary on the top of the branches, like the drawings of St. Edwardsii in 
Hoox., Fl. Bor. Am., I, tab. 31, which exactly represent our plant; other- 
wise they agree with f. humilis FENZL. 
Cerastium L. 
32. Cerastium alpinum L., var. vel subsp. Fischerianum (SERINGE) 
Torr. & Gray, Fl. N. Am. I, 1838, p. 188; A. EAstwoop, Botan. Gazette, 33, 
1902, p. 139; E. REGEL, Plantæ Raddeanæ, I, 2, 1862, p. 438; C. Fische- 
rianum SERINGE in D. C. Prodromus I, 1824, p. 419; CHAMISSO & SCHLECH- 
TENDAL, Linnæa I, 1826, p. 60; Hoox., Fl. Bor. Am., I, 1830, p. 103. 
Purren’s list, Arctic coast. 
King Point. Flowering specimens were collected in the last days 
of June 1906 (28th). 
The Cerastium-species here in question (see pl. III, fig. 22) differs con- 
siderably from the typical C. a/pinum L., and I should think that future 
investigations will result in taking it as a separate species. 
It has been described by SERINGE in DE CANDOLLE’s Prodromus. 
This description is short and insufficient, but shortly afterwards A. DE 
CHAMISSO (in Linnæa, 1826) added many useful distinctive characters. 
He says that in habit it resembles C. cæspitosum Gris. (C. vulgatum 
Auctt., C. vulgare HARTM.) much more than C. alpinum L.; nevertheless 
it is more nearly allied to the latter, from which it differs (1. c. p. 61):
