Name: Dendrobium alaticaulinum

Etymology: The genus name Dendrobium is derived from the Greek words dendron for “tree” and bios for “life,” describing the epiphytic growth habit of many species. The specific epithet alaticaulinum refers to the strikingly winged or angled shape of the shoots.

Origin/Distribution: New Guinea.

Location/Habitat: The species grows epiphytically in moist montane forests. We recommend bright, filtered light, high humidity, and excellent air circulation. Temperate conditions of approximately 14–25°C during the day and 10–18°C at night are favorable. During active growth, the roots should be kept regularly moist but well-aerated.

Description and Notes: Dendrobium alaticaulinum develops slender, characteristically angled to winged shoots and bears small, attractive flowers on mature shoots. We cultivate the species in a fine to medium, highly aerated orchid potting mix or mounted under correspondingly high humidity. During the growing season, we water and fertilize regularly with water that is as soft as possible. When growth slows, we reduce watering slightly without forcing a pronounced dry rest period.
