1909. No.8. VASCULAR PLANTS COLLECTED IN ARCTIC NORTH AMERICA. 49 
The description given in O. E. SchuLz’s monograph of the genus is 
detailed and excellent, but I do not understand why he maintains the 
variety oxyphylla TRAUTV., the less so as he himself quotes RICHARDSON’Ss 
own specimens as belonging to this form. If we look for the description 
of the variety by TRAUTVETTER (I. c.), we find that the main distinction 
from the type is given in the words: »foliis ... distincte pinnatisectis«. 
TRAUTVETTER here refers to the term: »folia digitatim pinnatas used by 
RICHARDSON (1 c.) when describing his species. Now this term is un- 
doubtedly incorrect, as the leaves are pinnate and not digitate, but the 
leaflets stand rather near to each other, and that is what RicHarpson has 
meant by >digitatim pinnatas (TRAUTVETTER incorrectly writes: »digitato- 
pinnata<). ©. E. SCHULZ uses other characters as distinctions between the 
type and the variety, but I think he is not right in fixing in such a 
manner the varietal name of TRAUTVETTER which is based upon a mis- 
understanding. 
We have a specimen collected by RicHarpson during the Franklin 
voyage in the Copenhagen herbarium, and this agrees in all respects with 
the plants from the Gjöa Expedition, as well as with the other Arctic 
American specimens. I do not find any reason therefore for maintaining 
the var. oxyphylla, not even as a mere form. 
J. Macoun (Catalogue, 1883, I, p. 41) gives "C. digitata (?) RicHaRDs.” as a mere syno- 
nym to C. pratensis L., which is evidently quite wrong. As pointed out by O. E. Scaurz 
our species belongs to a section of the genus remote from C. pratensis L. 
Later James M. Macoun (Canadian Record of Science, Jan. 1897, p. 268) records 
€. digitata RicH. from near the mouth of the Mackenzie River and the country between 
Lake Athabasca and Chesterfield Inlet and points out, that it has been referred to C. pra- 
tensis by American botanists, but is easily distinguished by its creeping rhizome and the 
scape of the leaves.

King Point. Only one flowering specimen of usually large size 
has been collected in July 1906 (by GopFRED Hansen). 
Draba L. 
51. Draba hirta L., Sp. pl., ed. 2, Il, 1763, p. 897. 
King Point. Flowering on June 2oth— July 3th, 1906. 
Herschell Isl. With young pods, July 17th, 1906. 
Most of the specimens of D. hirta are tall and large-flowered, with 
large lanceolate-obovate radical leaves and per well-developed, ovate, 
somewhat amplexicaule stem-leaves — thus agreeing with the form collected 
by F. KJELLMAN at Port Clarence and named f. subamplexicaulis (C. A. 
Mey.) KJELLM. (Vega-Exp. Vetensk. Arb., Stockholm, 1883, II, p. 46).
