About This Orchid
Bulbophyllum debruynii J.J.Sm. is an accepted orchid species in the World Checklist of Vascular Plants maintained by the Royal Botanic Gardens, Kew. The name was published in 1929, and the checklist gives its native range as W. New Guinea. It is recorded as a pseudobulbous epiphyte associated with wet tropical conditions. This accepted-name record is intended to separate the species from historical synonyms and horticultural hybrids; conservation, trade, or specimen-level work should consult the cited protologue and current regional monographs.
The visual profile follows the genus and life-form pattern: compact pleurothallid orchid with small leaves and fine inflorescences. Exact flower size, petal and sepal proportions, color, fragrance, pollinator association, and flowering date are species-specific and are not inferred from the checklist alone. This row therefore identifies those details as requiring species-level confirmation rather than presenting an invented generic trait as fact. For cultivation, reproduce the recorded wet tropical setting with the light, moisture, temperature, humidity, and airy medium described below.
Growing & Care Information
Temperature
Warm-intermediate: 20 to 30 °C (68 to 86 °F) days and 18 to 24 °C (64 to 75 °F) nights
Humidity
65 to 85% relative humidity with vigorous airflow to prevent rot in a moist environment
Light Requirements
Medium to bright filtered light; about 1,000 to 2,000 foot-candles; shield leaves from intense midday sun
Watering
Keep the root zone evenly moist while growing, allowing only a brief surface dry-down; water less in cool or dull weather
Blooming Season
Variable by species and locality; verify the species-level phenology; many orchids bloom seasonally or in response to mature growth and temperature cues
Flower Colors
Species-specific; verify against a monograph or authoritative specimen image; Bulbophyllum flowers may show a broad range of orchid colors and markings
Native Region
W. New Guinea
Habitat
Wet tropical habitat; recorded growth form: pseudobulbous epiphyte; compact pleurothallid orchid with small leaves and fine inflorescences.
Potting Media
Fine bark and sphagnum with perlite in a shallow pot or basket; mount on cork or tree fern only where high humidity and frequent watering can be maintained.
