Name: Phalaenopsis pulcherrima var. marmorata (O'Brien) O.Gruss & Roeth
Synonyms: Doritis pulcherrima var. marmorata O'Brien
Etymology: Phalaenopsis = moth-like (Greek phalaina = moth, opsis = appearance); pulcherrima = the most beautiful (Latin); marmorata = marbled — refers to the characteristic spotted or patterned leaf markings.
First description: Originally described by James O'Brien in 1883 as a variety under Doritis; later reclassified into the genus Phalaenopsis by Olaf Gruss and Jürgen Roeth.
Origin / Distribution: Southeast Asia
Location / Habitat: Grows terrestrially or lithophytically in sandy soils, humus-filled rock crevices, and light forests from the coast to lower elevations. The species prefers very bright, warm, and humid locations with distinct seasonal differences.
Description & Notes: Phalaenopsis pulcherrima var. marmorata differs from the nominate form primarily by its highly decorative foliage. The thick, leathery, distichous leaves exhibit a striking, dark green marbling pattern on a light green background. The rigidly upright, often branched inflorescence produces numerous long-lasting flowers in shades ranging from pink to intense violet-purple in succession. The three-lobed lip is pointed steeply upwards and has a pointed, arrow-shaped side-lobe structure.
In cultivation, this variety is more robust and requires more light than most large-flowered Phalaenopsis hybrids. It tolerates very high light levels (filtered sun) and requires warm to hot conditions year-round. An airy mixture of medium-grade pine bark and some sphagnum moss or expanded clay is suitable as a substrate. During the growth phase in summer, it should be watered regularly; in winter, after blooming, the substrate should be kept slightly drier, though without letting the plant dry out completely.
In-vitro culture: You will receive a flask with 4 young plants. The plants are generally already large enough to be deflasked. After opening, carefully remove the nutrient medium completely from the roots using lukewarm water and place the young plants in fine, airy bark with some sphagnum. For the first few weeks, we recommend high humidity, warm temperatures, and bright but protected light with gentle air movement. Keep the substrate evenly slightly moist, but not waterlogged; once well-established, light and drying intervals can be gradually increased.
