Hedyscepe
''Hedyscepe canterburyana'', the Big Mountain Palm or Umbrella Palm, is the sole species in the genus ''Hedescepe'' of the Arecaceae family. It is endemic to Lord Howe Island, Australia and is threatened by habitat loss. It is a solitary palm with a distinct crownshaft, and bears unisexual flowers of both sexes. With the ''Rhopalostylis'' palms of Norfolk Island and New Zealand it forms the botanic subtribe Rhopalostylidinae. If differs from ''Rhopalostylis'' in minor floral details including having more than six stamens, and in being protandrous rather than protogynous. The two genera were formerly included in Archontophoenicinae until a revision in (Dransfield, Uhl et al., 2005).
==Description==
''H. canterburyana'' is a slow-growing palm up to 10 metres tall which grows on mountain forests, cliffs, and exposed ridges overlooking the sea, at about 400 to 750 metres of altitude. It has a slender, close-ringed trunk, a prominent silvery crownshaft and a compact crown of dense, dark green, stiffly arching recurved fronds somewhat reminiscent of those of ''Howea belmoreana''. The egg-shaped fruit are deep red when ripe, and about 4 cm long. They appear in densely bunched fruiting spikes from below the crownshaft. Each fruit contains a single seed.
