Phyllocladus is a small genus of conifers, now treatedin the Family Podocarpaceae.
However, genetic analysis shows that they fall within the Podocarpaceae; their removal fromthis family leaves the remainder of Podocarpaceae as a polyphyletic taxon.As modern scientific classification requires taxato be monophyletic, Phyllocladus is best treated within the Podocarpaceae.
Theseed cones are berry -like,similar to those of several other Podocarpaceae genera, notably Halocarpus and Prumnopitys, with a fleshy white aril ; the seeds are dispersedby birds, which digest the soft fleshy aril as they pass the hard seeds in theirdroppings.
Phyllocladus aspleniifolius : Phenology, germination, and seedling survival
Abstract The timing of foliar and sexual development of Phyllocladus aspleniifolius (Gymno-spermae: Podocarpaceae) were recorded at Mt Field in Tasmania.
The number of germinants two springs after seed fall reflected the variation in annual seed production and suggests that pulses in regeneration are likely although soil-stored seed and immigrant seed may offset this effect.
Grows in sub alpine and mountain forests and scrub in North and South Island at altitude of 1500 ft - 5000 ft. In Westland and Southland descends to sea level.
This is the most striking of the three New Zealand species of Phyllocladus but is seldom seen in cultivation.
As a lawn specimen it is excellent and its growth is sufficiently slow that it does not become too tall.
Abstract Gametophyte development and embryogeny is described in Phyllocladus trichom- anoides D. Don for the first time, and the proem- bryo of P. asplenifolius var.
Proembryogeny in both the species investigated conforms to the pattern established for a wide range of genera in the Podocarpaceae, resulting in a three- tiered proembryo in which all the cells of the E tier are binucleate.
This is seen as strong evidence of a close affinity between Phyllocladus and other gen- era of the Podocarpaceae, and supports the reten- tion of the genus in that family.
Individual specimen entries are published in the sample database supplied with The Compleat Botanica for species or varieties of this supra-generic taxon.

Abstract Four populations each of Phyllocladus trichomanoides and P. alpinus were investigated by isozyme analysis of foliage extracts.
Genetic identity between the two Phyllocladusspecies is high (I = 0.880).
The electrophoretically detectable genetic differences between the two species do not support a hypothesis suggesting hybrid origin of the South Island populations of P. trichomanoides.
It is a fast grower and tolerates sun and shade which, together with its attractive whorled branching, make it a popular tree in cultivation.
When seeds germinate, the young plant forms needle-like leaves at lower levels and phylloclades at higher levels that take over the function of leaves.
