Gongora
Gongora is a genus of orchids belonging to the family Orchidaceae, comprising around 65 species primarily found in Central America and tropical South America, with a significant concentration in Colombia. These epiphytic plants are distinguished by their pendulous inflorescences bearing numerous flowers that hang upside down, often with distinctive fragrances and waxy blooms. The genus is named in honor of Antonio Caballero y Gongora, a Spanish viceroy and governor.

About Gongora
Gongora is a genus of orchids recognized for their unique floral structures and diverse geographical distribution. Comprising approximately 65 species, Gongora orchids are predominantly found in Central America and tropical South America, with Colombia being a significant center of diversity. These orchids inhabit a broad range of environments, from humid coastal forests to mountainous regions in the Andes, reaching elevations as high as 1,800 meters.
The genus name honors Antonio Caballero y Gongora, a notable Spanish viceroy of New Granada and governor of Peru during the late 18th century, who was associated with a significant botanical expedition.
Botanical Characteristics
All species within the Gongora genus are epiphytes, meaning they grow on other plants, primarily trees, for support rather than in soil. They exhibit a sympodial growth habit, characterized by the development of new shoots from the base of existing ones. Their aerial roots are typically thin and white, forming dense clumps that firmly anchor the plant to its host. The pseudobulbs are conical, ridged, and can produce multiple flower stalks. Each pseudobulb typically supports two leathery, heavily veined leaves, which can grow up to 30 cm in length.
Floral Features
The inflorescence of Gongora orchids emerges from the base of the pseudobulbs and is pendulous, meaning it hangs downwards. The numerous flowers are borne on this drooping stem and are characterized by their upside-down orientation, with the lip facing upwards. A distinctive feature of the genus is the almost circularly bent pedicels that support the blooms. The flowers themselves often have waxy textures, and many species are noted for their distinctive fragrances, which can range from smelling like unburned candle wax to spices like nutmeg, cardamom, or cinnamon. The reproductive structures, or pollinia, are attached to a stipe, adapted for pollination.
Ecology and Relationships
Many Gongora species have an interesting ecological relationship with ants. Ants are attracted to nectar droplets produced by the orchid and also to pest insects like aphids and mealybugs that feed on the orchid's sap. While the ants do not prey on these pests, they may tend to them, possibly benefiting the orchid by keeping pest populations in check. Gongora is taxonomically closely related to the genus Cirrhaea and is part of the subtribe Stanhopeinae.
Taxonomy and Discoveries
While some Gongora species have been known to European botanists for a considerable time, recent decades have seen the discovery of several new species, alongside reclassifications and ongoing taxonomic studies. The genus is complex, with some species lacking comprehensive descriptions, and others existing in isolated populations. Advanced techniques like DNA fingerprinting are expected to contribute to a more precise understanding of the genus's taxonomy in the future. The genus has been divided into several subgenera and sections, reflecting its diversity.

Frequently Asked Questions
What is Gongora and where does it come from?
Gongora is a genus of orchids with about 65 species. They are native to Central America, Trinidad, and tropical South America, with most species originating from Colombia. They inhabit diverse environments, from humid forests at sea level to mountainous regions up to 1,800 meters.
What are the distinctive features of Gongora orchids?
Gongora orchids are known for their unique pendulous inflorescences, from which numerous flowers hang upside down. The flowers often have waxy petals and sepals and can possess distinctive fragrances. Their growth habit as epiphytes, with aerial roots anchoring them to host trees, is also characteristic.
How are Gongora orchids pollinated?
The pollination mechanism involves a specialized stipe that holds the pollinia. While specific pollinators are not detailed for all species, their floral structures are adapted for insect pollination, with some species attracting ants through nectar droplets, which in turn may protect the orchid from pests.
What is the origin of the name Gongora?
The genus Gongora was named in honor of Antonio Caballero y Gongora, who served as the viceroy of New Granada (modern-day Colombia and Ecuador) and governor of Peru during the time of the Ruiz and Pavón botanical expedition.
What are the growth habits of Gongora orchids?
All species within the Gongora genus are epiphytic, meaning they grow on other plants, typically trees, for support. They exhibit sympodial growth and have thin, white aerial roots that form dense mounds, often seeking additional anchorage and nutrients.
Do Gongora orchids have a scent?
Yes, many Gongora species are known for their distinctive fragrances. The scents can vary, with some described as smelling like unburned candle wax, while others are reminiscent of nutmeg, cardamom, or cinnamon.

Barbosella
Barbosella is a genus of creeping orchids comprising about 20 species, primarily found across the West Indies and Latin America, from Mexico down to Argentina. These orchids are distinguished by their solitary flowers, which feature a unique lip base that functions like a ball and socket joint. The genus was named in honor of João Barbosa Rodrigues, a notable investigator of Brazilian orchids.
Dryadella
Dryadella is a genus of miniature orchids, recognized for their small, often conspicuously spotted flowers borne at the base of the leaves. Originally part of the Masdevallia genus, these orchids are native to a wide range across Central and South America, from Mexico to Argentina. Many species thrive when mounted on cork or treefern, with some, like Dryadella edwallii, being particularly amenable to cultivation.
Aganisia
Aganisia is a small genus of orchids native to South America, characterized by their dwarf, epiphytic climbing habit. These orchids are found in mountainous or savanna forests and along rivers, producing small flowers that typically range from rose-tinted violet to blue-tinted violet. The genus name is derived from the Greek word for gratitude, possibly referencing the sweet scent of its blooms.
