Plant Profile

Platycerium stemaria

(plat-ih-SEER-ee-um ) (sta-mar-ee-uh)

Triangle Staghorn

Subfamily Platycerioideae

Genus Platycerium

“Large-growing wide shields, wavy at the top and short lived and are seasonal.  The fertile fronds are often shiny on the upper surface, and quite hairy on the underneath.  The fertile fronds show a main division into two lobes and each of these lobes divides once again.  There are two spore patches on each frond, one on each main lobe, in the area of its division.  When mature the spore patches are dark brown.  More difficult to grow, requiring temperatures of 80°F (26.6°C) and not below 50°F (10°C). Needs high humidity and frequent watering. Semi-erect, large foliar fronds with a silvery cast when young. Produces pups readily in moist areas.

Broad fertile and dark green suggest a filtered light is best and shelter from wind.  This condition also suggests less spore production.  It is expected, if grown in brighter light, the fertile fronds would tend to be narrower and shorter with more spore.” – Halling
