Strawberry pine (Eckenwalder 2009).
This is the only species in Microcachrys Hooker f. 1845. The genus is most closely related to Saxegothaea and Pherosphaera, two other genera of small-leaved, shrubby podocarps with an affinity for cold, wet places.
Evergreen, monecious or temporarily dioecious prostrate shrubs, up to 30 cm tall, much-branched from prostrate leaders up to 1 m long. Branches numerous, spreading, ascending. Twigs long, slender, whip-like, clad in scale-like leaves, quadrangular in cross section. Leaves on whip shoots mostly decurrent, lanceolate, up to 5 mm long with an acute apex. Leaves on lateral twigs decussate, imbricate, triangular, 1-1.5 × 1 mm, keeled, with an obtuse apex; stomata only on internal (adaxial) surface; leaves persist for many years on the main shoot. Pollen cones terminal, recurved, 2.5-4 mm long. Seed cones terminal, usually on different branch systems than the pollen cones, ovoid to globose, 6-8 mm long, fleshy and bright red when ripe; fertile scales round, each with an inverted seed partly covered by the epimatium (Dallimore et al. 1967, Farjon 2010).
This species grows with and resembles Diselma archeri and Pherosphaera hookeriana. See Diselma for a table that assists in distinguishing these species.
Australia: W Tasmania, in alpine dwarf scrubland above 1000 m elevation, usually spreading by means of runners (whip shoots) across rock outcrops or through low vegetation. Common associates include the other Tasmanian dwarf conifers, Diselma archeri, Pherosphaera hookeriana, and Podocarpus lawrencei, as well as the tree Athrotaxis cupressoides, and various angiosperms (Farjon 2010). Based on data from 23 collection localities, it grows at elevations of 760 ±300 m. Within its range, mean annual temperature is 8°C, with an average minimum in the coldest month of 0°C, and a mean annual precipitation of 1600 mm (Biffin et al. 2011, Table S5). Hardy to Zone 8 (cold hardiness limit between -12.1°C and -6.7°C) (Bannister and Neuner 2001).
There appear to be no reported uses. The species is quite rare in cultivation.
I found it reasonably common in rocky alpine areas in Mt. Field National Park and Cradle Mountain National Park.
The genus name is from the Greek MIKROS, small, and CACHRUS, catkin, describing the pollen cones (Dallimore et al. 1967). The epithet refers to the 4-angled branchlets.
