Flowering Piants and Ferns from North-Western Greenland. 21 



89. Taraxacum hyparcticum Dahlst. 



Wash. L.: Morris Bay (5. VI, sterile and identification doubtfuU; 15. VI, 

 in bud). 



Ingl. L.: Marshall Bay, on a sunny hill-slope (2. — .5. VII, flow.); Kensse- 

 laer Bay, on river-banks (13. — 17. VII, flow., very ricli material); in the inland 

 behind Anoretiik, Rensselaer Bay (20. VII, flow.). 



NyGAARD writes in his notes that at Rensselaer Bay all kind of 

 shades of colours from nearly white to rich or deep yellow were present. 

 Dahlstedt mentions T. hyparcticum with whitish to pale yellow co- 

 rollas. 



In 1923 I have recorded T. phyniatocarpum J. Vahl from the N. 

 coast of Greenland, but on closer examination I fmd that most of the 

 material (if all?) rather is to be referred to the closely allied T. hyparc- 

 ticum^ which really is very difficult to distinguish from T. phymatocar- 

 pum^ when no fully ripe fruits are present. 



Ericaceæ. 



90. Cassiope tetragona (L.) Don. 



Ingl. L.: Dallas Bay (30. VI, flow.); Marshall Bay (2. VII, flow.); Rensse- 

 laer Bay (11. VII, flow. and some flowers already withered). 



Murch. S.: Piteravik (11. XI, winter-stage) ; E. of Igdloluarsuit, on moraine 

 (27. VIII, late flowering spec). 



91. Rhododendron lapponicum (L.) Whbg. 



Ingl. L.: Sunny hill-slope near Advance Bay (24. VI, no flow.). 



Murch. S.: Igdloluarsuit, south facing slope (28. VII, no flower); Mac Cor- 

 mick Bay (7. IX, no flower, but a few capsules and flowerbuds for the next year; 

 rich material collected). 



Pirolaceæ. 



92. Pirola grandiflora Radius. 



Ingl. L.: Near Advance Bay (27. VI, sterile; ample material); Rensselaer 

 Bay (13.— 20. VII, no flow.). 



Murch. S.: Igdloluarsuit, at the talus of a fowling cliff (28. VII, flow.); on 

 sandy soil in a river-bed (30. VII, in full flow.); amongst stones on a moraine ridge 

 (9. VIII, in full flow.); Mac Cormick Bay (27. Vllf, still in full flow.). 



Plumbaginaceæ. 



93. Armeria vulgaris Willd., var. sibirica (Turcz.) Rosenv. 



Seems to be rare: 



Murch. S.: Amongst stones on a river-bed at Mac Cormick Bay (7. IX, with 

 nearly ripe fruits). 



Scrophulariaceæ. 



94. Pedicularis arctica R. Br. 



(cfr. H. G. Simmons, Rep. 2nd. Norw. Arct. Exp. Fram 1898—1902, 

 No. 2 (1906) p. 31, pi. 2).
