[[File:Diselma RW.jpg|thumb|left| Scale-like leaves appear in a square in cross section and red coloration of juvenile cone formation. Photo: R. Wiltshire]] [[File:D. archeri cones.png|thumb|left
''
Bark is rough and scaly and often weathered revealing a reddish-brown inner bark.
Being a [[gymnosperm]] no flowers are produced, instead seed development occurs on the surface of the scale-like leaves which are modified to form cones (see image).<ref>Raven, P.H., Evert, R.F., Eichorn, S.E. 2003. Biology of Plants. 6th Edition. W.H Freeman and Company</ref>

== Taxonomy ==
'''''Diselma''''' : ''dis'' (meaning double) and ''selma'' (meaning upper) is a reference to either the two fertile scales in the female cone or the arrangement of the overlapping leaves in the opposite alternating pairs.
'''''archeri''''' is named after botanical collector William Archer (1820-1874) who was also a Fellow of the Linnaean Society, an architect and Member of Parliament for Deloraine, Tasmania.<ref>{{Cite web|url=http://www.anbg.gov.au/gnp/gnp11/diselma-archeri.html|title = Diselma archeri - Growing Native Plants}}</ref>

== Distribution ==
''Diselma archeri'' is endemic to Tasmania and is only found in high rainfall alpine and subalpine areas of the South West and Central Plateau of the state. Its altitudinal range varies from approximately 580-1400m above sea level. Like many Tasmanian conifers ''D. archeri'' is very fire sensitive and will only occur in fire free areas of alpine [[coniferous]] [[heath]] and [[montane]] rainforest.<ref>{{Cite web|url=http://www.utas.edu.au/dicotkey/dicotkey/CONIFERS/sDiselma.htm|title = Key to Tasmanian Dicots}}</ref> This species can form a small tree (3-4m) in closed rainforest at high altitude and some ecologists consider ''Diselma'' to be one of the seven genera which can be used as rainforest indicators in Tasmania.<ref>Jarmen. S.J., Brown, M.J. 1983. A definition of cool temperate rainforest in Tasmania. Search14. P. 81-87</ref> In more open coniferous heathland the Dwarf Pine grows more prostrate and only reaches approximately 1-2m in height.
