74 Nr. 2. C. H. OSTENFELD and C. SYRACH LARSEN: 
state in both these areas; the only point of uncertainty 
is the extent of the two localities in question. 
Of the two smaller localities still further eastwards, the 
most southerly lies in Tatra, where the larch occurs scattered 
on the slopes towards the valley of the Waag (CIESLAR: 
l. c. p.4; Hayek: l. c. pp 343 and 395; and SAGORSKI and 
SCHNEIDER: Fl. Centralkarpathen, I, 1891, p. 569). The 
forest-line here is formed of stunted larches, which in the, 
highest parts grow at an elevation as high as 2000 m. 
above sea-level. The other locality north-west of Tatra lies 
in Babia göra on the frontier between Czeko-Slovakia and 
Poland (VIERHAPPER in Oster. Bot. Zeitschr. LXI, 1911, p. 
229. Vide CIESLAR in Centralb. ges. Forstw. XL, 1914. p. 182, 
Note). 
Beyond the area of distribution mentioned here, L. decidua 
has also been reported far out towards the south-east in 
the Transsylvanian Alps, where Hayek cites two localities, 
one to the south (see Map VII), and the other to the west 
of Kronstadt, in the Cibin Mountains, where it is found 
in the neighbourhood of the Zood valley at an elevation of 
1400 m. above sea-level and upwards. The first-mentioned 
locality has also been described by Maack (Zeitschr. Forst. 
Jagdw. XXXVI, 1904, p. 644), who gives a detailed account 
of forest remains, including specimens of considerable 
dimensions in the mountains, growing at altitudes from 
1300—1600 m. above sea-level, and mentions that timber 
for the castle at Sinai was fetched from this spot. The 
larch in both these localities is undoubtedly the original 
species; the only point not decided being whether the tree 
is the typical L. decidua, as there seem to be reasonable 
grounds for believing that it may be L. d. var. polonica.
