Stiles . — T he Podocarpeae.

The confusion in nomenclature between the four genera mentioned above 
was ultimately cleared away by Sir J. D. Hooker in i860. 1 
This plant in habit is not much more than a straggling shrub found on 
some of the mountains of Tasmania. As regards reproductive shoots the 
plant is dioecious. As well as in this it differs from Saxegothaea , as far as 
external characters are concerned, in the form and arrangement of the leaves 
and in the nature of the fruit. 
3. Dacrydium , Soland. 
The first description of a plant under the generic name Dacrydium in 
1786 2 contains practically no mention of its structure, but is chiefly con- 
cerned with the use to which the plant is put in the making of a kind of 
Spruce-beer. Lambert 3 appears to be the first writer to append a botanical 
description to the name. 
This genus differs from Saxegothaea and Microcachrys in the reduction 
of the number of megasporophylls in the strobilus, and from Podocarpus in 
the absence of a stalk to the ovule, and in the freedom of the inner integument 
from the nucellus, and of the outer from the inner. 
There is some range of habit among the sixteen species of this genus. 
Some, such as D . Kirkii , are trees reaching a height of 100 feet, the 
majority are small trees about 20 or 30 feet high, while others are 
low shrubs. The species are generally dioecious, but Kirk 4 describes 
D. laxifolium as monoecious or dioecious. 
Two species of the genus have been examined in the course of this 
work, D. Franklini , Hook, f., and D. cupressinum , Soland. Both are forest 
trees, the former being the Huon Pine of Tasmania, the latter the Red 
Pine of New Zealand. 
4. Podocarpus , L’Herit. 
The first plant of this genus to be given a botanical name was P . nagi, 
(Thunb.) Pilger, which was described by Thunberg 5 under the name of 
Myrica Nagi. Gartner in 1778 realized that the plant belonged to a 
previously undescribed genus, and gave it the name of Nageia Japonica . 6 
Two species are confused in this description, 7 so the generic name Nageia 
has been replaced by the later name of Podocarpus , which was first used by 
Labillardiere 8 in 1806 for the species now known as Phyllocladus asplenii- 
folius. In the next year L’Heritier’s name Podocarpus elongatus appeared. 9 
L. C. and A, Richard in 1826 first gave the name Phyllocladus to what had 
previously been known as Podocarpus asplen iifoliusP The Vienna Rules 
regarding botanical nomenclature reject the earlier name Nageia in favour
