26 Morten P. Porsitp. 
A decided southern type, on the mainland hitherto only found 
to 65°10" and not common till S. of 62° (Ros.). Lowland plant. 
Fructificates in favourable places. 
Covered by thick layers of snow in winter. 
I 9. Botrychium lanceolatum (Смег.) Ancstr. 
Disko: Engelskmandens Havn, only found once and in a single specimen 
(E. P.), afterwards often searched for in vain. 
А decided southern type, in Westgreenland only known from 
several places between 60° and 61730' and single specimens from 63° 
and 64°25’. 
Our specimen was abundantly fructificating (Aug. 1911). 
Ш. Equisetaceae. 
i 10. Equisetum variesatum ScHLEIcH. 
In bogs, swamps and heath among mosses and other vegetation, 
often in water some part of the year; frequently forming pure associa- 
tions, especially on periodically inundated sand. Thus at the river- 
mouths in the sandstone-districts. 
Common throughout the whole range. 
A widely distributed species, the northern limit of which must 
be N. of 72°30’, but is not yet known. 
At Disko-Bay ascending the hills to 800 m. 
Mostly sterile; fructificating specimens found especially in favour- 
able places. 
During winter covered by snow, often also by ice. 
4 11. Equisetum scirpoides Мтснх. 
In luxuriant not too moist herb-mats and bush-land, often in 
shade. 
Disko: Very rare, only found a few times in the neighbourhood of Godhavn 
69°15’ (Br.; Bg.; Th. H.; Kr.) and now most likely extinguished because of the cut- 
ting down of the willows for fuel. 
Diskofjord: Kuanerssuit (69°33’ P.). 
Mainland: Tasiussaq S. of Egedesminde, 68°40’ (W. & H.),! Kangerdluar- 
ssuk 8. of Agto 67°59’ (E. P.), in Nordre Stromfjord (P. & E.), at several places and 
rather common in the fjords inland from Holsteinborg (P. & E.). 
A decided southern type; among the above mentioned localities 
the north-limit is to be found.! S. of Holsteinborg it seems to become 
rarer or perhaps overlooked. 
' In herb. Jon. LANGE I have seen a specimen labelled ‘‘Tasiussaq ?°/1 1887. 
Ryder.” If correct that would mean the place at 73°22’, but I think the 
record must be due to some confusion.
