The European Larch, L. decidua, extends from Dauphiné 
and Provence northwards and eastwards through the Alps 
to a point 40—50 km. south-west of Vienna, where its 
main area of occurrence reaches the most extreme 
northwesterly point. In the north-west corner of Yugo- 
Slavia and the north-east corner of Italy it reaches 
southwards to lat. 46° N., extending to lat. 441/2° N. in the 
west (WILLKONM: Forstliche Flora, 1887, p. 144), and 
probably even a trifle further southwards to between lat. 
44*/2°—44° N. It also occurs spontaneously towards the 
north-east in the southern district of the Sudetic Mountains 
and Tatra, and there may be two isolated localities in the 
Transylvanian Alps. 
The occurrence of the larch in the French Alps has 
been mentioned sufficiently frequently (GRENIER & GODRON: 
Fl. France, III, 1855, p. 156; HONORÉ ARDOINE: Fl. Alp. 
Maritim, 1867, p. 346; Rouy: Fl. France, XIV, 1913, p. 359), 
but a detailed description, such as, for example, Curist’s 
account of the species in Switzerland, is wanting. It is 
found in Savoy, Dauphiné, and in the Provincial Alps 
and no doubt extends somewhat into the Maritime Alps, 
its southern limit being probably, as already stated, 
between lat. 44° and 44'/2° N. BRIQUET's account of the 
larch in the French Alps which approach the Lake of 
Geneva (BRIQUET in Ann. Conserv. & Jard. Généve, III, 
1889, pp. 46—146), indicates an occurrence in larger or 
smaller quantities at an elevation of 600—1800 m. above 
sea-level, and points to the fact that the natural forests 
have been greatly over-exploited, and finally, that it is
