Grammatophyllum scriptum

Description

Grammatophyllum scriptum is a species of orchid. The flowers are generally up to 4.5 cm wide, green with dark brown markings, held in racemes of up to 150 blooms. Grammatophyllum scriptum is native to south east Asia and is found in low-lying coastal areas (sea level to 100 metres). In the Philippines, this type of orchid is called "tawatawa". Due to their large size, plants are rarely found in cultivation outside botanical institutions. Grammatophyllum, sometimes abbreviated in horticultural trade as Gram, is a genus of 13 currently known orchid species. The name is derived from the Greek words 'gramma' (a line or streak or mark) and 'phyllon' (leaf), referring to the parallel leaf veins or the markings of the perianth. This epiphytic genus occurs in dense rainforest from Indo-China, to Indonesia, the Philippines, New Guinea, and the Southwest Pacific islands. The species produce several racemes, arising from the base of the pseudobulb, with many yellow-green to olive-green, waxy flowers with dark purplish-red marks. The pseudobulbs are enveloped by sheaths. These are medium-sized to very large orchids, including the giant orchid (Grammatophyllum speciosum), believed to be the largest orchid species in existence. Its pseudobulbs can grow to a length of 2.5 m. Plants can develop into gigantic clusters weighing from several hundred kilograms to one ton. The roots form spectacular bundles. The more modest bell orchid (Grammatophyllum scriptum) is another well-known species, with pseudobulbs of 20 cm, from which originate 3 to 4 stout leaves with a length of 1 m. Grammatophyllum multiflorum is one of the longest-blooming orchids in existence: it can be in bloom for nine months. See also Dendrobium cuthbertsonii, whose flowers have been reported to last up to ten months each. Grammatophyllum 'Tiger's paw' is a hybrid from G. elegans and G. fenzlianum.
