Platycerium sporophytes (adult plants) have tufted roots, growing from a short rhizome, and 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,

180-543: Is 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 . The species Platycerium bifurcatum and Platycerium superbum are commonly cultivated as ornamental plants . These oddly shaped ferns grow on trees and rocks and can be found in gardens , especially tropical gardens . Staghorns can be propagated by spores produced on

The feature was visited by Victoria University's Antarctic Expeditions (VUWAE), 1976-77, led by Christopher J. Burgess. The name derives from the discovery of a parachute and abandoned airdrop packaging in

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. If the conditions are right, the spores will germinate naturally, on surrounding trees. A Platycerium gametophyte
380-481: The top margin of these fronds will grow into an open crown of lobes; catching rainwater, falling forest litter, bird/animal droppings, and even an occasional fallen 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. The spores are borne in sporangia , clustered in large sori that are usually positioned on
