 Valley in the Dovrefeld. (New Phvtologist. IX. p. 353—374. 

 2 pl. 8 figs. 1910.) 



In this district of Norway the authors observed the flora and 

 Vegetation during August. The area is indicated on a chart, and 

 from Kongsvold (900 m. alt.) upwards to Knutshö (1700 m.) and 

 other summits there is a zonation of the Vegetation. The larger 

 plant-communities are dealt with and the plant-lists include manj^ 

 crj'^ptogams. The following are described: a) meadows and pastures 

 of the river-belt; b) exposed-rocks et low levels, c) rocks recently 

 exposed, d) banks of debris and rubble, e) disused roads, a series 

 of habitats where colonisation is in progress, and where widely 

 varying conditions favour a large number of species; /) the wood- 

 land of the lower slopes where Betula odorata, forma alpigena is 

 dominant with a characteristic undergrowth; g) belt of shrubland 

 of B. nana and arctic species of Salix; h) alpine lichen-pasture 

 where on mats of lichens the flowering plants are scantily repre- 

 sented. Six plate-figures from photographs show examples of Vege- 

 tation from the above zones. 



Material collected during the excursion and examined in detail 

 is also dealt with and figures are given showing: comparison of 

 the size and internal structure of B. nana from 1000 m. alt. and 

 from 1500 m.; Sedum Rhodiola leaf, internal structure from a dry 

 änd a wet place respectively; leaf-structure of Phippsia {Catabrosa) 

 algida, etc. 



The absence of Sphagnum spp. is emphasized, its place being 

 occupied by Hypnum sarmentosum, etc. The paper also includes 

 numerous notes of ecological interest. W. G. Smith.

Verff. beschreiben eine sehr einfache und rasche Gewinnungs- 

 methode des Eutins aus frischem bltihenden Kraut von Fagopyrutn 

 esculentutn. Mittels dieser Methode fanden sie in frischen Blättern 

 l,78o/o, in frischen Blüten 0,71o/o, in frischen Stengeln 0,09o/o und in 

 trockenem Kraut (c. 65% Wasser), l,027o Rutin. Die Angaben 

 Wund er ich s (s. dieses Cbl.) über die Eigenschaften des Rutins 

 werden durch die Versuche der Verff. im wesentlichen bestätigt.
