Dendrobium cinnabarinum is from Borneo. The plant is a lithophyte and epiphyte and inhabits lower montane and moss forests at elevations between 600 and 2,200 metres. Inflorescences measure 5cm and bear 3-5 flowers that each measure up to 8cm across.
This plant is near flowering size. Grow Dendrobium cinnabarinum in a pot with moss or bark, or on a mount, with moderate shade and keep it evenly kept moist all year. The plant will grow well in an intermediate to warm greenhouse or indoors if given suitable conditions. Plants need very high humidity.
