Name: Chysis David Portilla
Parents: Chysis tricostata × Chysis limminghei 
Etymology: Chysis comes from the Greek chysis = melting / casting (referring to the fused pollinia); the epithets refer to the parent species (tricostata = three-ribbed; limminghei = named in honor of Count Alfred de Limminghe).


Location / Habitat: Cultivated. The hybrid combines the characteristics of the lowland, warm-growing C. limminghei (sea level) with the slightly cooler, moist mountain forest conditions of C. tricostata (around 1,360 meters). In cultivation, the cross shows itself to be highly adaptable in the intermediate range.
Description & Notes: This hybrid grows epiphytically and produces thick, spindle- to club-shaped pseudobulbs that usually hang with age. The leaves are soft, long, and strikingly strongly ribbed (plicate). The inflorescence develops in spring at the same time as the fresh new growth from the basal leaf sheaths. The waxy, long-lasting flowers combine the coloring of both parents: They often show a creamy white to light yellow base color that transitions to a rich orange or reddish-brown towards the tips, paired with an intensely red-magenta patterned lip.

The plant tends to partially shed its leaves in winter. During active growth in summer, it requires plenty of water, high humidity, and regular fertilization. After the bulbs mature in autumn, watering is significantly reduced (pronounced, drier dormant period) to stimulate flower bud formation in spring. However, a complete shriveling of the pseudobulbs should be avoided.

Location/Cultivation Conditions: Intermediate to warm at around 16–27 °C and bright filtered light. Water abundantly during active growth; after the pseudobulbs mature, reduce watering without allowing the bulbs to shrink significantly.
