About
The ornamental orchid species Phalaenopsis hieroglyphica ( fal-i-NOP-sis hy-roh-GLIF-ik-ə) is native to certain islands of the Philippines. Its flowers are creamy white with transverse markings that resemble glyphs. Through hybridization, growers have successfully created flowers with different shapes and colors while retaining the glyphs. Since 1975, the species has been protected under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
How to grow it
Commonly P. hieroglyphica blooms in spring, with three to four star-shaped flowers that open simultaneously and last two to three months; a well-established specimen with keikis can produce more than 50 flowers. Their fragrance is said to be faintly rose-like or strongly citrus-like. The background of the flower can be white to ochre, sometimes with a tinge of green at the tips, and the glyphs on the sepals and stamens can be cinnamon or a purple hue. The flowers are comparatively larger and the glyphs more pronounced than those of P. lueddemanniana. The characteristic glyphs are retained in P. hieroglyphica hybrids.
As a monopodial epiphyte, it is found growing on and hanging down from trees in shady locations on the islands of Polillo, Palawan, Mindanao (in Surigao del Norte and Surigao del Sur), and Luzon at elevations below 1,700 feet (520 meters). Of its genus, this species grows in the coolest and deeply shady locations of humid forests. Not much is known about its natural habitat, including its pollinators.
