Dendrobium bigibbum ssp. bigibbum grows on the western side of Cape York and has been commonly called the "Weipa Cooktown orchid" because it is found around Weipa, a bauxite mine on the western side of Cape York. Its flowers are smaller than Den. bigibbum ssp. phalaenopsis and they grow to 5 cm across on canes of length similar to those of Den. bigibbum ssp. phalaenopsis. In flower, it is easily identified by the white spot on the labellum.

Dendrobium bigibbum ssp. phalaenopsis grows between Mount Molloy and Cooktown on the eastern side of Cape York and is the original "Cooktown Orchid". It may have larger flowers (up to 7 cm across) than other varieties of the species. There are a number of cultivars of this including 'Albomarginatum' (with white margins on the petals and sepals) and 'Hololeucum' (white flowers). Pseudobulbs can grow to 1.2 m. Selective breeding has produced some much larger, paler and flatter flowers, so much so that judges at shows often question the validity of naming them Dendrobium bigibbum ssp. phalaenopsis
