Cypripedium macranthos, the large-flowered cypripedium, is a species of orchid. It is native to Russia and East Asia.
C. macranthos has a widespread distribution across Russia (European Russia and Siberia), Kazakhstan, Mongolia (Huvsgul, Hentii, Mongol Daguur, and Khyangan), Japan, Korea, China (Hebei, Heilongjiang, Jilin, Liaoning, Nei Mongol, and Shandong provinces) and Taiwan. It may also be found in Belarus and Ukraine, but this has not been confirmed. It grows in a variety of habitats from sea level to 2,400 m (7,900 ft) above sea level, including meadows, forests, woodland edges, scrub, riparian areas, and grassy slopes. It prefers well-drained, humus-rich soils but tolerates both acidic and alkaline substrates. Though it prefers slightly shaded areas, it will also grow in more open habitat. [1]
C. macranthos is a herbaceous plant growing 25–50 cm (9.8–19.7 in) tall. The upright stem arises from a short, thick rhizome with several sheaths near the base. Each plant has three to four elliptic or elliptic-lanceolate leaves, each measuring 10–15 cm (3.9–5.9 in) by 6–8 cm (2.4–3.1 in). The inflorescence typically bears a single red, pink, or purple flower. Rarely, two flowers may be present, or the flower may be white in colour. The dorsal sepal is ovate-elliptic with a pointed tip, measuring 4–5 cm (1.6–2.0 in) by 2.5–3 cm (0.98–1.18 in). The synsepal is ovate with a slightly two-loved tip, measuring 3–4 cm (1.2–1.6 in)1.5–2 cm (0.59–0.79 in). The petals are lanceolate and each measure 4.5–6 cm (1.8–2.4 in) by 1.5–2.5 cm (0.59–0.98 in). The labellum measures 4.5–5.5 cm (1.8–2.2 in) and is deeply pouched, with a small opening measuring 1.5 cm (0.59 in) across. The fruit is an ellipsoid capsule measuring approximately 4 cm (1.6 in) long. [3] [4]
C. macranthos is similar in appearance to Cypripedium tibeticum , which has slightly larger, darker flowers. [4]
C. macranthos is capable of reproducing both sexually and vegetatively. Flowering occurs from June to July, with fruits appearing from August to September. [3] Its flowers are self-compatible and primarily pollinated by bumblebee queens. [5]
Cypripedium × ventricosum is a naturally occurring hybrid between C. macranthos and C. calceolus . [3] [6]
Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe and Africa (Algeria), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids, lady's slipper orchids, or ladyslippers; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "Cyp." The genus name is derived from Ancient Greek Κύπρις (Kúpris), an early reference in Greek myth to Aphrodite, and πέδιλον (pédilon), meaning "sandal".
Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper. It is a perennial member of the orchid family found in undisturbed northern and montane forests. It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard. The genus Calypso takes its name from the Greek signifying concealment, as they tend to favor sheltered areas on conifer forest floors. The specific epithet, bulbosa, refers to the bulb-like corms.
Phragmipedium kovachii is an orchid species found to be new to science in 2001, native to the Andean cloud forests of northern Peru. A species with terrestrial habit and growing in clumps of several individuals, it displays showy pink to purple flowers up to 20 cm (8 in) wide. It is currently considered a critically endangered species by the IUCN, due to overcollection in the wild.

The plant shares the same appearance with T. philippinensis except for the rich dark color of the blooms and slight variation of the perianth. This species was first described in 1877 by the German botanist Heinrich Gustav Reichenbach, an expert on the orchid family. At that time, thousands of newly discovered orchids were being sent back to Europe, and he was responsible for identifying, describing and classifying many of these new discoveries.
