Species: P bifurcatum P veitchii
Common name: Staghorn
Also, elkhorn fern
Conservation status: . . .
Etymology:
Common names arise from their uniquely shaped fronds
Genus derived from the Greek words platys meaning "flat" and ceras meaning "a horn", referring to the shape of the fronds
Spores:
The spores are born in sporangia, clustered in large sori that are usually positioned on the lobes, or at the sinus between frond lobes
If the conditions are right, the spores will germinate naturally, on surrounding trees
Leaves:
Adult plants bear two types of fronds - basal and fertile fronds
Basal fronds are sterile, shield- or kidney-shaped, and laminate against the tree, to protect the fern's roots from damage and desiccation
In some Platycerium species, the top margin of these fronds will grow into an open crown of lobes; catching rainwater, falling forest litter, bird/animal droppings, and even the occasional fallen baby bird or deceased animal, these plants build up their own “compost” system of nutrition over many years
Fertile fronds bear spores on their undersurface, are dichotomous or antler-shaped, and jut out or hang from the rhizome
Stem & branches:
Some species of Platycerium are solitary, having only one rhizome
Other species form colonies when their rhizomes branch, or when new rhizomes are formed from root tips
Roots:
Adult plants have tufted roots, growing from a short rhizome
Habit:
Epiphytic fern
Habitat:
Tropical and temperate areas
Distribution:
Native to South America, Africa, Southeast Asia, Australia, and New Guinea
Species:
World: 18
Australia: 4
Additional notes:
A genus of fern species in the polypod family, Polypodiaceae
Platycerium gametophytes are a small, heart-shaped thallus.
Platycerium have diverged into four natural groups
Several Platycerium are strongly adapted to xeric conditions, with a naturally drought-tolerant metabolism method having been reported for P. veitchii
