1898-1902. No. 2.] VASCULAR PLANTS OF ELLESiMERELAND. 27 



P. capitata in a group Macranthae. Doubtless the section Anodontae 

 of Maximowicz is very heterogeneous, the Sceptra and Acaules at least 

 should be removed from it, but it is rather difficult to say if P. capi- 

 tata should be united with P. Sceptrum in the same section, sub-genus, 

 or genus. The shape of the flower indeed supports such an arrange- 

 ment, but there is perhaps too great a difference in the form of the cap- 

 sule, which also yields a prominent character of the genus Sceptrum, 

 (RuDB.) Hartm. The capsule of Sceptrum is almost spherical (as also 

 in P. acaulis, Wulf.), but it seems perhaps not to be so in P. capi- 

 tata as far as can be judged by the descriptions of Bunge in Lede- 

 BOUR, 1. c. 



P. capitata grows chiefly in marshy soil and flowers rather late, 

 not before the beginning of July. 



Occurrence. Grinnell Land: Discovery Harbour, Hart, Greely. 

 Hayes Sound district; rather scarce: Promontory at the mouth of Flagler 

 Fjord, "Fort Juliane", interior of Beitstad Fjord, Twin . Glacier Valley 

 (875); Bedford Pirn Island, Rice Strait side (1249); Nares expedition. 

 South coast; rather common in the archaean district: Fram Fjord (1626); 

 Harbour Fjord in several places (2334, 2509, 2577); and also in the lime 

 and sandstone region: Muskox Fjord; Goose Fjord, in several places; 

 Walrus Fjord. 



Distribution: North-western Greenland, Foulke Fjord; Arctic 

 American Archipelago, Arctic America, Unalaschka, East Arctic Siberia 

 to Taimyr Peninsula, Kamshatka.

Most arctic travellers and authors who have written about arctic 

 floras seem to have been able to distingui.sh this species from others, 

 so far at least, that when a P. Mrsuta is mentioned one may be gene- 

 rally certain that it is the real one. But as the above list of syno- 

 nyms shows, it also figures sometimes under other names. The reason 

 for these mistakes, I think, is mostly to be found in the indication of 

 the floras about the colour of its flowers. Both in Hartman, Skand. 

 Fl. (11th Ed., p. 119), and in Neuman & Ahlfvengren, Sv. Fl.,p. 147,
