neighbourhood of the Danmark Harbour (76° 46' N. Lat., 18° 43 W. 

 Long.) on Germania Land, but smaller collections have been 

 made at different points along the coast northwards to Hyde Fjord 

 on Peary Land (83° 18' N. Lat.). The list contains 92 species, of 

 which Alsine Rossü is new to the flora of the whole of Greenland, 

 and Draba siihcapitata has not previously been recorded from East 

 Greenland. 



Most of the species are commonly distributed arctic species; of 

 some interest are the two arctic varieties of Aira {Deschampsia) 

 caespitosa, var. arctica (Trin.) Siram. and var. pumila Ledeb., fürther 

 the record of the rare grass Plewopogon Sahinae. 



Under each species are given its distribution within the area, its 

 habitat and the flowering time. 



Reproductions of photographs show some of the more interesting 

 species and also a peculiar "pillar-form" into which some species, 

 e. g. Lesqiievella arctica and Potentilla pulchella, develop when gro- 

 wing on the wind-side of graveley slopes where Xh^y are snowless 

 in Winter. The "pillars" consist of freel}^ projecting stems covered 

 with old wind-blown remains of leaves and at the top a small rosette 

 of green leaves. 



It may be worth while to enumerate the few species collected on 

 Peary Land, the large Island north of Greenland: Glyceria an- 

 gustata, Poa ahhreviata , Salix arctica, Stellaria longipes, Papaver 

 radicatiim, Saxifraga oppositifolia, Poteiitilla pulchella and Dryas 

 octopetala var. intermedia. 



The plates and figures in the text are reproductions of photo- 

 graphs of dried specimens with the exception of a plate showing large- 

 flowered Saxifraga oppositifolia on the spot. C. H. Ostenfeld.

In der Nachkommenschaft der Bastardierung von Kartoffelblü- 

 ten treten vielfach Eigenschaften auf, welche den Eltern fehlten. 

 Eine bisher überhaupt nicht bei Kartoffelsorten beobachtete Färbung 

 ist die hellschwefelgelbe des mittleren vortretenden Teiles der Kro-

Coville, F. V., Experiments in Blueberry C ulture. (Bull. 

 193. U. S. Bur. Plant Ind. p. 100. with 18 pl. 34 textfig.) 



This bulletin is an ecologic one in that it presents the soil 

 requirements of the blueberry plant (which is that of an acid peat 

 soil) the peculiarities of nutrition (where endrotrophic mycorhiza play 

 an important role) and a final somewhat detailed description of 

 methods of pot and field culture where it was determined that seed- 

 lings of swamp blueberry can be raised as robust plants to a maxi- 

 mum height of 27 inches after 12 months from germination. Details 

 of the structure of the roots, seeds and seedlings are given pro- 

 minent place. John W. Harshberger.
