Habitat: Brazil. Cattleya dolosa grows on rock outcroppings or sometimes trees.
Plant Size: Medium. The plant is very similar to Cattleya walkeriana. Each pseudobulb has two leaves.
Flower Size: 5″ (to 12.5 cm)
Flower Description: Fragrant. The flower of Cattleya dolosa is similar in size and form to Cattleya walkeriana. Each 3 inch flower stem has between one to (rarely) four flowers. Cattleya dolosa has very waxy flowers of heavy substance which are long-lived.
Bloom Season: Spring
Growing Temperature: Intermediate to Warm. In its native environment, summer days average 82-84 F (28-29 C), and nights average 71-72 F (22 C), with a diurnal range of 11-12 F (6-7 C). Winter days in its habitat average 77-79 F (25-26 C), and nights average 64-65 F (17-19 C), with a diurnal range of 9-11 F (5-6 C).
Growing Information:
Light: Standard Cattleya light. Bright, indirect light.
Humidity: Provide 80-85 percent humidity for most of the year. Its acceptable for summer humidity to drop into the 75-80 percent range.
Water: Cattleya dolosa should be watered regularly throughout the year, but they must dry rapidly after watering. Make sure that the plants never stay dry for long periods of time, however. Give mounted plants a daily misting in summer with a thorough soaking of the entire plant and slab twice a week in summer, or three times a week in extremely hot weather (adjust for your climate). Water should be reduced somewhat in winter, but plants should never stay dry for long periods.
Growing Media: Cattleya dolosa is frequently grown mounted on cork slabs or in baskets, but some growers report success using pots with extremely open fast draining medium such as coarse bark nuggets. Whatever the choice of medium, it is critically important that the roots dry rapidly after watering or root rot is a near certainty. Use very small slabs for mounting this species because larger slabs retain to much water. Tree-fern slabs hold more water and should only be used only in very dry growing conditions. When mounting, do not use sphagnum moss between the mount and the plant because it retains too much moisture and promotes rot. Divide, repot, or remount only when new root growth is just starting. This lets the plant become established in the shortest possible time with the greatest success.
Additional Information: It was once thought that Cattleya dolosa was a natural hybrid between Cattleya walkeriana and Cattleya harrisoniana or Cattleya loddigesii. However, after years of hybridizing, Cattleya dolosa was not able to be reproduced through experimentation and was awarded species status. It is rare in cultivation but worthy of a spot in your collection.

Habitat: Belize, Guatemala. Cattleya bowringiana prefers to grow on exposed rocks near free-flowing streams. They can be found near cliffs between 200 and 900 meters. Atmospheric humidity is high at all times. It may grow as a lithophyte in rocky ravines, with the plants splayed out on rocks with little shade. Interestingly, Cattleya bowringiana has occasionally been found growing as a terrestrial on quartz sand along rapidly flowing streams in addition to its more traditional habitat of large tropical trees.
Plant Size:a Medium to Large. Cattleya bowringiana has bold, club-shaped pseudobulbs, that can reach 10 to 15 inches in height, and are topped with two (sometimes three) leaves. The leaves are thick and leathery. Well-grown plants can reach 20 to 30 inches and produce up to 25 flowers per flower spike.
Flower Size: 3 inches (7.5 cm). The flower spike emerges from short-lived spates and grows to 10 inches (25 cm) before the flowers open. Flowers grow in clusters from a few (5 to 10) to a maximum of 15 to 25.
Flower Description: Flowers of Cattleya bowringiana occur in clusters and are very showy. Color is typically medium purple with a darker lip and a lighter throat. They have been described as a bouquet of flowers on a single plant. Flowers last up to 3 1/2 weeks.
Bloom Season: Fall, Winter
Growing Temperature: Cool to Warm. Cattleya bowringiana is easy to grow. As one reviewer put it, There is no special treatment for these plants; they just grow. The plant sends out new growths in late May or June that will mature by late summer and will flower without a rest period in late September and October (in the United States). Provide lots of water when actively growing.
Additional Information: Provide bright light and humidity with good air circulation. Provide a short rest by reducing water and fertilizer after blooming is finished. There is a coerulea (blue) form of this species available (Cattleya bowringiana var. coerulea). There are no true alba or semi-alba forms.
This species is named after an English orchid grower who lived in the late 1800s.

Cattleya amethystoglossa (the “amethyst-lipped Cattley flower”) is a bifoliate species of orchid from the genus Cattleya.
C. amethystoglossa is native to Brazil in the states of Bahia and possibly Espirito Santo, where it is found near sea level in close proximity to the Atlantic Ocean. C. amethystoglossa grows on palm tree trunks, rock, and large tree branches high in the canopy of evergreen trees. This plant is found growing in bright, airy, humid locations. Its native range has been greatly reduced due to habitat destruction, logging, and agriculture.
C. amethystoglossa is a tall plant and has pseudobulbs that grow to 3 feet (1 meter) tall. Each pseudobulb has two (occasionally three) leathery, green leaves at the top. This species is in the Bifoliate division of Cattleyas.
The flowers of C. amethystoglossa grow to 4 inches (10 cm) in diameter. Flowers are produced on terminal flower stems that develop at the apex of the pseudobulb. The unbranched inflorescence produces between ten and 30 blooms. C. amethystoglossa is fragrant. The petals and sepals are light lavender to pale rose in color with mauve or magenta spotting. The amount of spotting varies widely between individuals with some individuals demonstrating few spots. The lip is bright magenta in color and partially wraps around the column. The throat varies in color from white to pale yellow or gold. Flowers are produced from late fall to early spring.
C. amethystoglossa grows best in intermediate or warm growing conditions.
This species is closely related to C. guttata in many ways but differs in flower color and other minor botanical details. There have been a few coerulea and alba forms found in the wild.
There are several synonyms for this species: Cattleya amethystoglossa var. lilacina, Cattleya guttata keteleerii, Cattleya guttatta lilacina, Cattleya guttata prinzii, Cattleya guttata var. prinzii, Cattleya purpurina, Epidendrum amethestoglosum, Epidendrum elatius var. prinzii.

Acacallis Lindl. 1853, was a small South American genus with a few species from the orchid family Orchidaceae. According to the authoritative database of the Royal Botanical Gardens in Kew, the genus Acacallis Lindl. has become a synonym of Aganisia Lindl. All Acacallis species have now been synonymized with Aganisia species, except Acacallis rosariana V.P.Castro & M.M.Silva that has become an unplaced name.
The species of this former genus are found in the countries of Brazil, Colombia, Venezuela, Guyana, and Peru. Both species have flowers that generally reach 4 cm in width and whose color is rare among orchids, varying from a rose-tinted violet to a blue-tinted violet produced from a creeping rhizome.
