brevipes rather closely approaches that variety. Perhaps it would be 
best to keep @. brevipes as a distinct species until more observations of 
it can be obtained. 
To show the relationships and to facilitate the search for eventual 
new occurrences, I have annexed an 
Analytical Arrangement of the small Galium-species 
of N. Europe, Greenland and N. Atl. America. 
I. Corolla tetramerous. 
A. Leaves in whorls of 6—8, linear-lanceolate, with distinct mucro, 
5—10 mm. long, 1—2 mm. broad. Mature fruits warty, ab. 1 mm. 
in diam. Erect, 1.5—3 dm. high, retrorse-scabrous, with apical, 
richly flowered inflorescences. Not blackening when dried. 
Wet bogs, meadows and lake-borders in temp.-bor. Europe and Iceland, 
(not in America). 
G. uliginosum L. 
Fig.: Fl. D. 1509; Rchb. 1193; Hegi: VIST. tab. 248. fig. 4; Lindman: 
pag. 505. 
B. Leaves in whorls of 4, linear-lanceolate to oblanceolate-spatulate, 
obtuse, without mucro. Fruits glabrous. 
a. Inflorescence forming small dichotomous cymes with se- 
veral flowers, the peduncles of which become gradually hori- 
zontally distant. Plant erect, 2—5 dm. high, sparingly branched, 
retrorse-scabrous, blackening in drying. Leaves 10—12 mm. 
long, 2—4 mm. broad. Fruits united nearly to the top, 2.5—3.3 
mm. in diam. 
Wet meadows, temp.-bor. Europe, (not in Iceland), temp.-bor. N. America 
to Québec and Newfoundland. 
G. palustre L. 
Fig.: Fl. D. 2764; Rchb. 1185, I; Hegi: VI, 1. tab. 248,3; Lindman: p. 503; 
Gray Man.: p. 749. 
In Europe several varieties are discerned; see f. inst., Neuman & Ahlfvengren 
p: 107: 
b. Flowers in single pairs or in very few-flowered cymes. 
a. Leaves normally erect, 15—25 mm. long, faintly scabrous 
on margins and midribs of lower side. Stem erect, 1—8 dm. 
high, freely branching from base. Peduncles not horizontally 
distant. Fruits 2.5—3.5 mm. in diam.
