Phyllocladus toatoa
''Phyllocladus toatoa'', known as Toatoa (Māori) or Blue Celery Pine is a species of conifer in the Podocarpaceae family, endemic to New Zealand. It was formerly referred to as ''P. glaucus''.
==Botanical Description==
''P. toatoa'' is a small dioecious or monoecious, conical or bushy tree that grows to in height and in diameter at maturity on average.〔 The outer bark ranges in color from dark brown to a silvery-brown.〔 ''P. toatoa'' is distinguishable from other species in the ''Phyllocladus'' genus due to its whorled pinnate phylloclades with diamond shaped segments.〔 Attached to whorled branches are cladodes.〔(【引用サイトリンク】url=http://cber.bio.waikato.ac.nz/courses/226/Gymnosperms/Phyllocladaceae.html )〕 ''P. toatoa'' flowers between October and December, leading to a fruiting stage between January and March.〔(【引用サイトリンク】url=http://www.nzpcn.org.nz/flora_details.asp?ID=1116 )〕 The fruit is a nut sitting in a cup shaped envelope.〔 Each fruit contains 3-4 3 mm square shaped seeds which are black at maturity.〔 Cultivated mature plants flower annually.〔 The species is wind pollinated by male cones which produce large quantities of pollen.〔 Mature seeds are dispersed from the cone through swelling of the cone bracts ejecting the seeds to the ground.〔 Distribution is limited resulting in many seeds landing on the ground under the female tree.〔 Establishment of the species over a large area indicates that ''P. toatoa'' is dispersed by wind and birds.〔 ''P. toatoa'' is difficult to propagate and is relatively slow growing.〔(【引用サイトリンク】url=http://web.auckland.ac.nz/uoa/science/about/departments/sbs/newzealandplants/seed-plants-nonflowering/native-conifers/phyllocladaceae-celery-pine/toatoa.cfm )〕
