Platycerium holttumii

Platycerium holttumii is a large mainland Southeast Asian staghorn fern of the P. grande group, native from northern Peninsular Malaysia through Thailand to Indochina and southern China. It grows high on trees in seasonally dry lowland forest and has to ride out a hot, nearly rainless dry season from December to March. Grow it mounted, bright and warm, with a drier rest in winter.

Where it grows wild

Epiphytic on trunks and large branches in lowland to low montane monsoon forest, where the tall shield fronds collect litter and rain; exposure is bright because the canopy is partly deciduous in the dry season.

Records from 40 to about 600 m; the measured sites lie at 40-730 m.
