Stray Contributions to the Flora of Greenland I—V. 43 
In its basal leaves the new variety is said to be quite like the rare 
Rocky Mountain species, À. Grayi Brirron, but differing in the floral 
parts. And in FERNALD’s recent work: “Persistence of Plants in Unela- 
ciated Areas, etc.’’, Mem. Am. Ac. Sc. 15. III, 1925, p. 299, the plant 
is considered a strict endemic, characterizing the unglaciated summits 
of the region mentioned. 
This plant is, however, also known from Greenland, where it was 
detected by A. G. Natruorst, 1883, at Unartuarssuk on the east coast 
of Disko, and described under the name of R. pygmaeus var. *Langeana, 
(Ofv. K. Vet. Ak. Förh. 1884, N. 1, p. 46), and good photographs were 
given in the annexed plate. LANGE included the plant in his Conspectus 
Florae Groenlandicae, pars II. 1887, p. 254, and translated Naruorst’s 
original Swedish description into Latin: 
1—4” alta, caespitosa, foliis radicalibus trisectis, segmentis magis minusve 
longe petiolatis, sursum latioribus, intermedio saepius 3—4-fido, lateralibus 2—4 
fidis, foliis caulinis subsessilibus, ad basin usque 3—5-fidis, laciniis laceolatis v. 
sublinearibus 
The plant was found again, in 1890, by N. Harrz at Qutdligssat 
70°3’ N., and several other places on East Disko, (Medd. om Grl. 15, 
1894, p. 52), and by the present writer at its type locality in 1898 and 
later. It also occurs on West Disko in Mellemfiord at Kuänit, 69°45’ N., 
(M. P. P.), and at Qasigigssat, 69°52’ N., (A. E. P.). 
On the eastern coast of Greenland var. Langeana has been mentioned 
by Hartz and Kruuse (Medd. om Gril. 18, p. 331, 1895 and ibd. 30, 
p- 167, 1905) from three localities lying between 70°30’ and 71°40’ N. 
All Greenland localities, so far, are in the sedimentary sections of Green- 
land, not in the Archean. 
In spite of the widely different shape of the leaves NATHORST 
doubted that his plant was a separate species, as in typical R. pygmaeus, 
too, the basal leaves show some tendecy to become more deeply cleft. 
This doubt was emphasized by Hartz and Kruuse who state that 
the var. Langeana is connected with the main form by intermediate 
forms. Hartz, especially, mentions such forms from Ritenbenk, in 
W. Greenland, 69°44’ N., which is in the gneissic area. And a similar 
statement has been made by myself (Medd. om Grl. 50, p. 375, 1912) 
from plants collected in W. Greenland, 71°—73° N., in the gneissic 
area. My statement, however, was a mistake; the plants in question are 
only somewhat luxuriant forms of typical À. pygmaeus. Having at present 
no access to the specimens of Harrz or Kruuse, I must for the subse- 
quent remarks be contented with my own observations from Disko. 
Lastly, K. Jessen has made an elaborate study of the morphology, 
anatomy and biology of the arctic Ranunculaceae in Medd. om Gril. 36,
