Name: Catasetum saccatum Lindl.

Etymology: The genus name Catasetum is derived from Greek and refers to the characteristic antennae of the male flowers. The specific epithet saccatum means “sac-shaped” and describes the striking shape of the flower.

First described: 1845 by John Lindley.

Origin/distribution: Tropical South America.

Location/habitat: Epiphytic in warm, seasonally moist forests. During the growing season, we recommend plenty of light, warmth, and generous watering. Temperatures of around 18–30°C are well suited. The pronounced dormant period begins with leaf drop; then we reduce watering significantly and keep the plant drier until new growth begins to grow vigorously again.

Description and notes: Catasetum saccatum produces robust, elongated pseudobulbs and seasonally deciduous leaves. The unisexual flowers are particularly interesting: male and female flowers differ distinctly, and the male flowers possess the pollinium-ejection mechanism typical of Catasetum. We use a very airy substrate and fertilize regularly during vigorous growth.
