Calanthe triplicate
C. triplicate is a perennial which thrives in shaded, hot and humid conditions.   It is a large terrestrial orchid* which grows on the evergreen forest floor.   Most orchids belonging to the genus Calanthea bloom in spring but this species blooms in summer.
C. triplicate forms corms** which are 2cm in diameter and propagate by division.   Some corms develop leaves which have vertical creases and are 30 to 50cm in length.   Some corms also develop a flower stem up to 80cm in length where many flowers bloom at its tip.   The flowers are 3 -4cm in diameter and are white to ivory in colour.   The flowers have yellow to vermillion projections from the base of the colora.   The spur*** grows downwards and backwards from the flower and bends upward at its tip.   the flower on the flower stem bloom sequentially in an upward direction however each flower is short lived and wilts within a few days.
C. triplicate is used as a crossing parent with a coloured summer-flowering species to make another species with a better tolerance to heat.
Due to destruction of its favorite environment such as deforestation and collection for horticultural purposes, C. triplicate is designated as an endangered species (VU (Vulnerable)).

*   As with a usual plant, C. triplicate sets its root system in the ground and grows upwards.   Orchids are usually epiphytic and grow on trees or rocks, therefore it is called an epiphytic orchid.   However, on some occasions orchids such as Cymbidium are epiphytic and terrestrial.
**  This is a storage tissue which is formed at the base of the terrestrial stem.   It is a roundly thickened subterranean stem.  It contains one or more internodes and at least one growing point.
*** This is a long and thin tubular structure which extends from the base of the perianth (a general term of a corolla and a calyx).   It usually pools nectar in itself.   This feature is important for pollination, as the structure ensures that the pollinator has a similar length of proboscis to the length of the spur.   When these lengths are similar then pollen is only brought to and from flowers of the same species therefore reducing cross pollination.   In tropical or temperate regions such as a tropical rainforest, it is often the case that the plant has evolved to give its nectar only to the specific pollinator because diverse plants are mixed up there.
