This common epiphyte and occasional lithophyte grows in rainforest areas
around Brisbane.
The pseudobulbs grow to 90cm by 10mm with 3 to 6 apical leaves 13cm by
4cm. The flower stem grows to 12cm with up to 30 flowers 15mm across. The
flowers are yellow blotched with red brown outside.
This distinctive species with its slender pseudobulbs and yellow cupped
flowers cannot be confused with any other orchid with the exception of its
hybrids Dendrobium x suffusum and Dendrobium x gracillimum.
Dendrobium x suffusum is a rare hybrid with Dendrobium
kingianum and can be distiguished by its shorter pseudobulbs and
outside markings usually pink rather than red brown.
Dendrobium x gracillimum is a hybrid with Dendrobium
speciosum var. hillii and can be distinguished by its longer
thicker pseudobulbs and larger more numerous flowers which are not
blotched on the outside. |
