Mr. Bentham refers this plant to Libocedrus, thus extending 

 the geographical distribution of this genus, already sufficiently 

 remarkable, inasmuch as one species is native of New Zealand, 

 two others of Chile, and another of the B-ocky Mountains be- 

 tween 38° and 41°. The Tunan plant has the habit of Thuya 

 § Thuyopsis, and is intermediate between it and true Libocedrus. 

 The genus is known also in a fossil state in deposits of the 

 Miocene period.

Carriere considers this distinct from var. nana ; but Gordon 

 treats them as identical.
