full_context: Document 1: Dracaena cinnabari: Dracaena cinnabari, the Socotra dragon tree or dragon blood tree, is a dragon tree native to the Socotra archipelago, part of Yemen, located in the Arabian Sea. It is so called due to the red sap that the trees produce.
Document 2: Cypripedium: 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 (one species), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids or lady's slipper orchids; 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 word ""Cypripedium"" is derived from the Late Latin: "Cypris", from Ancient Greek: Κυπρις  "(Kypris)" , an early reference in Greek myth to Aphrodite, and Greek: "pedilon", meaning "sandal".
Document 3: Cypripedioideae: Lady's slipper orchids (also known as lady slipper orchids or slipper orchids) are orchids in the subfamily Cypripedioideae, which comprises the genera "Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium" and "Selenipedium". They are characterised by the slipper-shaped pouches (modified labellums) of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower.

Document 6: Dracophyllum: Dracophyllum is a genus of plants belonging to the family Ericaceae, formerly Epacridaceae.

The name, "Dracophyllum" or dragon-leaf refers to their strong similarity to the unrelated "Dracaena", sometimes known as dragon tree. Although dicotyledonous, they resemble primitive monocots with their slender leaves concentrated in clumps at the ends of the branches; they are sometimes called grass-trees.
Document 7: Calypso bulbosa: Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper.

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.
