The genus Schoenorchis consists of 25, mini-miniature to small-sized, monopodial epiphytes occurring in Asia from the Himalayas to New Guinea.
Schoenorchis seidenfadenii is found in Thailand and Vietnam at elevations of 550 to 600 meters (1,804 to 1,969 feet). It is a miniature-sized, warm growing, creeping epiphyte. It flowers in the spring and summer on few to several flowered inflorescences. The flower size is 1 cm (0.4 inches). It has received a certificate of botanical recognition from the American Orchid Society and a bronze medal from the Orchid Society of Germany (D.O.G.). The Certificate of Botanical Recognition is Awarded to rare and unusual species with educational interest that has received no previous awards. The entire plant must be exhibited. This award is granted provisionally and filed with the judging center Chair pending taxonomic verification supplied by the exhibitor.
Progeny: None
Culture: Grow in bright, indirect light conditions. Temperature range: 66°F to 85°F (19°C to 29°C)

Masdevallia angulifera is endemic to Colombia and found in cool, moist, cloud forests at 1,800 to 2,000 meters (5,900 to 6,550 feet). It blooms in the winter through spring with fragrant flowers that can last up to three months. It should be potted in an open, fast-draining medium with some material to retain some moisture. Repotting is done every year in the late winter or early spring, or may be done anytime between autumn and spring, that does not interfere with flowering.

Rhyncholaelia digbyana (formerly known as Brassavola digbyana) is found in the southeastern Mexican states of Yucatan and Quintana Roo, with distribution extending through the Caribbean-facing lowlands of Belize into Honduras from 10 to 1,000 meters (33 to 3,281 feet). They grow on stunted trees in hot, humid lowlands near sea level. Often found in large colonies, it blooms in summer with large, fragrant flowers. This species does best mounted on wood or tree fern, given plenty of bright light and ample water while growing, and a lessening after the bulbs have matured. This plant, “Quinnelly’s Joy’ has both an AM and CCE awarded by the American Orchid Society.

Masdevallia ova-avis is endemic to Ecuador, where plants grow on the western slopes in northwest Ecuador at 2.000 meters (6,500 feet) in dense cloud forests and on steep road embankments. It is a medium- to large-sized epiphyte or terrestrial that blooms with flowers that have a spicy perfume. It blooms in winter, spring, and summer. Water and fertilizer should be reduced somewhat in the winter but never allow them to dry out completely.

Masdevallia exquisita is endemic to Bolivia, and the plants were found in trees found along a ravine or gorge at 1,800 meters (5,900 feet). The plant blooms in the summer. Water and fertilizer should be reduced in the winter, but do not allow them to dry out completely. Medium should be open and fast draining, with some materials added to retain some moisture.

Cattleya nobilior is found from Brazil to Bolivia at 500 to 700 meters (1.650 to 2,300 feet) in bright, airy positions on tree trunks or horizontal limbs of rough-barked trees, which grow at the very edge of the cliffs above the river valley. Water vapor from the river is carried aloft, thereby keeping humidity higher in the microclimate where Cattleya nobilior grows and providing some moisture, even during the long dry season. Blossoms are almost 5 in. (12 cm) across, the largest bifoliate Cattleya. Flowers open very flat with the segments fully expanded. They are very long-lasting with a faint but pleasant fragrance. Blooms in late winter or early spring. In cultivation, water should be reduced gradually in the autumn after new growths mature. Water once every 3-4 weeks with an occasional, early morning misting.

Cattleya intermedia is found in Brazil, Uruguay, and Paraguay. Plants are most often found in forests within a few miles of the coast and on nearby offshore islands in coastal or streamside swamps near sea level, but they are sometimes found at 300 meters (1,000 feet). Although sometimes described as fragrant, flowers usually have little discernible odor. This species is so variable that there are many named varieties, with even more horticultural varieties that are formally described. Plants bloom in spring, and a second flowering occasionally occurs in the autumn. Water and fertilizer should be decreased in winter with winter light as high as possible, short of burning the leaves. Plants are usually grown in pots or baskets filled with a very coarse, open fast fast-draining medium. Place in undersized pots that have room for only one to two years’ growth, so the medium does not stay wet for too long.

Bulbophyllum cochleatum native range of is Tropical Africa at 900 to 2,200 meters (2.953 to 7,28 feet. It is a warm- to cold-growing epiphyte that blooms in the spring through summer. Some growers claim that if you remove fertilizer during the winter, you can force blooming in spring. The truth is, is that no one knows what causes a Bulbophyllum to bloom. Much is still unknown about their environmental cues.

Cattleya acuensis is endemic to Brazil. They grow on moss or lichen-covered creekside trees in short, narrow ravines that extend down the mountainside for 200–300 meters (650–1,000 feet) to 1,950–2,070 meters (6,400–6,800 feet). Fowlie (1975) noted that plants in the habitat growing fully exposed to early morning and late afternoon sun were blooming while those in deep shade had no flowers and were not growing very well. In the habitat, they bloom in the late spring. Reduce water and stop fertilizing in the winter, but do not let them remain dry for long periods.

ATTEND IN PERSON OR VIRTUALLY, THE ORCHID DIGEST CATTLEYA SYMPOSIUM 11/8/25 TO LEARN MORE ABOUT THESE BEAUTIFUL ORCHIDS. INFORMATION: WWW.ORCHIDDIGEST.ORG Cattleya rupestris is endemic to Brazil and grows as a lithophyte primarily in the seasonally dry tropical biome and blooms in the fall. A dry winter rest is important. Use a fast-draining orchid mix so the roots dry out between watering. Photographer: Ron Parsons (www.flickr.com/photos/rpflowershots Grower: Fritz Bredeek
Aerides odorata is widely distributed from India through Southeast Asia and Indonesia to Borneo and the Philippines at sea level to 2,000 meters (6,550 feet) as epiphytes often growing in full sun. The flowers are very fragrant and bloom in late summer and early autumn. Plants are most often grown in baskets but may be mounted or grown in pots.
