The Species of the Genus Larix. 85 
of the three Transylvanian localities where var. polonica 
occurs), and in Bukovina near Krasna-Ilska (the most 
north-easterly), is L. sibirica, but this is insufficient for 
classifying them as such. Specimens in the Fl. Roman. 
exsicc. No. 331 b (Kew.; Brit. Mus.; Hort. Bot. Haun.) show 
that the larch at Ceahlau belongs to the intermediate type 
between L. decidua and L. sibirica, and the same is the 
case with the specimens (No. 331 a) from the Transylvanian 
district, Turda-Aries, Trascau, 1924. The last-mentioned 
locality lies a little to the south-west of Klausenberg (the 
most south-westerly of the three Transylvanian localities 
for var. polonica). 
The larches at Ceahlau and near Turda must accordingly 
be classified as L. decidua var. polonica, and the third 
locality just to the north of them in Bukovina should 
undoubtedly receive the same classification, while the 
classification of the two southern localities remains an open 
question until material comes to hand.
