Epiphyllum
Epiphyllum (orchid cactus genus) is a genus of 10 accepted epiphytic cacti in tribe Hylocereeae, native Mexico to tropical America, with flattened leaf-like branches and mostly nocturnal white flowers; horticultural 'epiphyllum hybrids' are mostly Disocactus crosses.
Epiphyllum oxypetalum
Epiphyllum oxypetalum, the queen of the night, is a spineless epiphytic cactus native from Central Mexico to Nicaragua, with fragrant white night-blooming flowers that wither by morning; IUCN Least Concern, widely cultivated as a houseplant.
Epiphyseal arrest
Epiphyseal arrest (physeal arrest, growth plate arrest): premature stoppage of growth plate function before maturity, usually from a physeal bar after fracture, causing limb length discrepancy or angular deformity; treated by bar resection, epiphysiodesis, or guided growth.
Epiphyseal plate
Epiphyseal plate (growth plate, physis): cartilage layer at long-bone ends driving longitudinal growth via resting, proliferative, and hypertrophic chondrocyte zones; closes in early twenties, leaving the epiphyseal line.
Epiphyseal stippling-osteoclastic hyperplasia syndrome
Epiphyseal stippling-osteoclastic hyperplasia syndrome (Pacman dysplasia, ORPHA:1952, OMIM 167220) is an extremely rare, presumably perinatally lethal autosomal recessive bone dysplasia with epiphyseal stippling, osteopenia, and osteoclastic hyperplasia; some authors consider it prenatal mucolipidosis II.
Epiphysiodesis
Epiphysiodesis is a surgical procedure that arrests or slows a growth plate in a child, used to correct limb-length discrepancy or angular deformity while growth remains, typically for predicted discrepancies of 2 to 5 cm.
Epiphysis
Epiphysis: the expanded, articular-cartilage-covered end of a long bone, formed from a secondary ossification center and separated from the metaphysis by the growth plate (physis) until fusion at skeletal maturity.
Epiphyte
Epiphyte: a plant that grows on another plant for support only, taking no nutrients or water from the host. Includes orchids, bromeliads, ferns, mosses, and lichens; about 10% of vascular plant species, threatened by climate change and deforestation.
Epiphytic ecology of Polypodiaceae
The epiphytic ecology of Polypodiaceae, the polypody family of over 1,600 fern species, covers canopy strategies: foliar water uptake, desiccation tolerance, humus collecting, and ant mutualisms in tropical forests.
Epiphytic ferns
Epiphytic ferns are ferns that grow rooted on the surface of another plant, making up roughly 10% of vascular epiphyte species worldwide, mostly in tropical forests.
