Potamogeton’s of Greenland, their life-cycle is a continued development 
of hibernacula. All are distinct southern types. 
th 257. Utricularia ochroleuca Hann. 
Mainland: Orpigssuit, 68°40° (Htz.) (Perhaps also the specimens named 
under U. minor from Tasiussarssuaq may belong to this species). — Otherwise only 
found at Ikerasak 70°30’ (Vh.). 
tt 258. Utricularia intermedia Hayne. 
New to Greenland! 
Mainland: In a small lake north of the great rapids Sarfarssuag 
in Nordre Stromfjord, 67°50’, we found amongst stems of sedges a mass- 
growth of an Utricularia. Besides the pond was filled with MWenyanthes 
and Hippuris etc. Although the plants were quite sterile, | have never- 
theless determined them to this species, not only because of the di- 
morphous leaves of which the bladderless ones are provided 
with numerous dense bristles, but especially on account of the 
very characteristic leaves of the hibernacula, bearing numerous 
bristles in bundles (see Apromerr Botan. Ergebn. Tab. 8. fig. 28 
—30). 
fi 259. Utricularia minor L. 
Mainland: Brede Bugt north of Jakobshavyn, 69°13’ (P.), Claushayn 69°5’ 
(Bg.), Tasiussarssuaq, 68°25’ (Bg. BI1.). 
A 260. Pinguicula vulgaris L. 
In herb-mats and on luxuriant humid spots in heath or open places 
in moss-bogs. 
Disko: South coast, numerous localities around Godhayn and in Disko- 
fjord (P.). 
Mainland: Nugssuaq peninsula, several localities near the mouth of the big 
valley (P.), from Paotut, 70°15’ and southwards some localities (P.); east of Disko 
Bay rather common, especially around the Sydost Bugt (numerous collectors) ; 
not seen in the archipelago of Egedesminde (K., P. & E.); several localities in Nordre 
Stromfjord (P. & E.); rather common in the fjords inland from Holsteinsborg (P. & E.). 
A southern type, without southern limit; north of the area found 
a few times in the North East Bay to about 71°15’ (S. H.), its northern 
limit in West Greenland. 
Richly, but late flowermg; in good summers and on favourable 
spots, ripe fruits are developed, at least on Disko. 
Covered by thick layers of snow during winter.
