Name: Lepanthes calodictyon 'Cup Leafs'
Etymology: calodictyon = beautiful net — derived from the Greek words kalos (beautiful) and diktyon (net), referring to the leaves’ magnificent veining; 'Cup Leafs' = horticultural term for this specific form with bowl-shaped, indented leaves.

First described: The nominate form was described in 1861 by Heinrich Gustav Reichenbach (Rchb.f.) in Xenia Orchidacea (2: 11). 'Cup Leafs' is a selected cultivated form.
Origin / Distribution: Cultivar / selected form. The parent species is native to western Colombia and western Ecuador.
Location / Habitat: Grows epiphytically in deeply shaded, extremely humid, moss-rich mountain cloud forests of the Andes at elevations of approximately 450 to 1,500 meters. It thrives in a permanently saturated, cool to intermediate microclimate, directly in the humid understory.
Description & Notes: Lepanthes calodictyon 'Cup Leafs' is one of the most fascinating and sought-after miniature orchids of all. It has tiny, upright stems with lepanthiform sheaths. The absolute highlight is its fan-shaped, delicate, slipper-like leaves: they display spectacular, contrasting, net-like veining (usually reddish-brown on a light green background) and a strongly wavy, often reddish-edged margin. What makes this 'Cup Leafs' selection special is that its leaves are noticeably rounder and sunken several millimeters deep in the center, forming a bowl or cup shape. The tiny red-and-yellow flowers sit flat against the leaf surface, but visually take a back seat to the spectacular foliage.

In cultivation, this sensitive rarity requires consistently intermediate to cool-temperate conditions and does not tolerate heat. As it has no storage organs, it must never be allowed to dry out. It is best grown mounted on cork with a moist sphagnum pad or in tiny moss pots at a consistently high humidity of over 80%. Gentle, continuous air movement is essential to prevent standing water in the cup-shaped depressions of the leaves and to prevent fungal diseases. Ideal for professional rainforest terrariums.

In vitro culture: You will receive a flask with 4 young plants. The plants are generally already large enough to be deflasked. After opening, very carefully remove the growing medium from the fine roots with lukewarm water and place the young plants on soft, moist sphagnum or in a very fine, airy substrate. During the first few weeks, we recommend very high humidity, sheltered light, and cool to intermediate temperatures with gentle, continuous air movement. Never allow the tiny plants to dry out completely, and avoid waterlogging on the leaves and roots.
