or Calocedrus, Kurz (in the Journal of Botany, 1878, t. 153). 
It is very nearly allied to Thuya. The distinguishing charac- 
teristics are to be found in the four-sided male flowers, in 
the erect cones, the smaller number of scales, of which the 
central pair are fertile, and in the frequent coalescence of the 
two uppermost scales into a vertical septum. The seeds, moreover, 
are solitary and winged obliquely. The cotyledons are two. 
The species are natives of China, the mountains of New Guinea 
(Libocedrus papuana, F. Muell.), North-west America, the 
Chilian Andes, and New Zealand (see R. Brown of Campster, 
‘Monograph of Thuya’). 
Species of this genus occur in amber and in the Miocene 
deposits of Spitzbergen and of Central Europe, and one species 
in the English Eocene below the London Clay (Starkie Gardner).
