Han. Tasmania, on the banks of Lake St. Clair, abundan 
Gunn (366). 
This genus is distinguished from Arthrotaxis by the ve 
different form and structure of its amenta, which are not 
broader than the branches; by the solitary, exposed seed 
and by the hyaline membranous testa surrounding it: from 
Cupressus the same character will also separate it. The 
len is of a different form from that of either of those genera, 
and the foliage also.

Has. Tasmania, on the summit of Mount Wellington an 
near Marlborough, in the elevated central parts of the 
island, Gunn (n. 226). 
This is one of the few species of Coniferæ which, except" 
ing the Junipers, never attains the size even of a shrub; ! 
is allied to the P. Totarra of New Zealand, but is a very dis- 
tinct plant. The Marlborough specimens are larger té 
those from Mount Wellington; in the former habitat : 
grows at about 3000 feet above the sea, and near the summ 
of the latter mountain at 4,000 feet. The pollen-grains 
all the Podocarpi which I have examined, except P. 
dioides, namely those of P. Totarra, P. Serruginea, and
