Name: Chysis tricostata × limminghei 
Etymology: Chysis comes from the Greek chysis = melting / pouring (referring to the fused pollinia); the epithets refer to the parent species (tricostata = three-ribbed; limminghei = named in honor of Count Alfred de Limminghe).
First description: This is an artificial cross (primary hybrid) that has not yet been officially registered under its own name with the Royal Horticultural Society (RHS).
Origin / distribution: Garden hybrid. The parent species are native to Central America (Mexico, Guatemala, Honduras, Nicaragua, Costa Rica).
Location / habitat: Cultivation-dependent. The hybrid combines the characteristics of the warm-growing lowland C. limminghei (sea level) with the somewhat cooler, humid mountain forest conditions of C. tricostata (around 1,360 meters). In cultivation, this makes the cross very adaptable to intermediate conditions.
Description & notes: This hybrid grows epiphytically and produces thick, spindle- to club-shaped pseudobulbs that usually hang as they age. The leaves are soft, long, and conspicuously strongly ribbed (folded-leaved/plicate). The inflorescence develops in spring at the same time as the new growth, emerging from the basal leaf sheaths. The waxy, long-lasting flowers combine the colors of both parents: They often have a creamy white to pale yellow base color that transitions toward the tips to a vibrant orange or reddish brown, paired with an intensely red-magenta patterned lip.

The plant tends to shed some of its foliage in winter. During active growth in summer, it needs plenty of water, high humidity, and regular fertilization. After the bulbs mature in autumn, watering is significantly reduced (a pronounced, drier rest period) to stimulate flowering in spring. However, the pseudobulbs should not be allowed to shrivel completely.

In vitro culture: You will receive a flask containing 4 young plants. The plants are generally already large enough to be removed from the flask. After opening, carefully rinse all the nutrient medium from the roots with lukewarm water and pot the young plants in fine, airy bark with a little moisture-retaining material. For the first few weeks, we recommend high humidity, warm to intermediate temperatures, and bright, sheltered light. Once new root growth is visible, gradually acclimate the young Chysis to normal growing conditions; do not impose a pronounced dry rest on young plants.
