Full shade Hot Summer

Common Name The Yellowish Phalaenopsis

Flower Size 1.28 to 1.48" [3.2 to 3.6 cm]

Found in northwestern Borneo on mossy rocks near streams as a small sized lithophyte with a very short stem carrying narrowly elliptic, acute, sessile leaves that blooms in the summer on slender, arching, racemose, shorter than the leaves, 2 to 4" [5 to 10 cm] long, 2 to 3 flowered inflorescence.

Very similar to P maculata but P luteola has larger flowers with a yellow background color in which the lateral sepals form a semi-circle making them falcate sub-parallel. In P maculata the flowers are smaller, they have an off white background color and the lateral sepals are divergent.
