Jewel of Malaya [Anoectochilus albolineatus] is a mountain orchid found from places ranging from Myanmar to Malaya with dark leaves beautifully variegated with bright orange-red venation. Wild Orchids of Malaya. Very easy to grow as a house plant.
Aerangis distincta by smithsonianmag: Only hawk moths with a proboscis of just the right length and curvature can suck up nectar from the bottom of the foot-long drinking tube. This specificity prevents cross-pollination between different orchid species.
