The following article was written for the Orchid Species Bulletin published by the Orchid Species Society, which is based in Brisbane, Queensland in August 2005.
Bear in mind that any cultivation notes refer to the sub-tropical conditions of Southern Queensland, Australia.
Eria
stricta Lindl.
was described by John Lindley in Collectanea Botanica in 1826. The
specific epithet comes from the Latin strictus (upright, straight) for the inflorescences.
Eria stricta produces clusters of fleshy upright cylindric pseudobulbs that are (2-) 6-14.5 cm long and 3-5 mm in diameter. The base of the pseudobulb is covered with membranous sheaths that are 2-3 cm long, which soon dry and become fibrous. Each pseudobulb bears two shortly stalked leaves at the apex. Oblong-elliptic to lanceolate, the leathery leaves are 7.5-12 (-19) cm long and 1-2 cm broad. Several (1-3) upright racemes that are 8-13 (-18) cm long are borne from the apices of the pseudobulbs.
The
racemes bear many small flowers that are 2-4 mm long along the upper half of the
inflorescence, which are densely arranged facing one side.
The flowers of Eria stricta do
not open widely so the blooms are bowl-shaped and they are white, sometimes with
a tinge of pink along the basal edge of the petals.
Its bilobed yellow and brown pollen cap gives the flower a cheery
face-like appearance. The outside of
the flowers is thickly covered with white wool, which extends also along the
green inflorescence. Unlike many
other species of the genus, the flowers of Eria
stricta seem to be comparatively long-lived and last for 2-3 weeks.
Eria stricta is distributed in subtropical valleys in the Himalayas (Nepal, Sikkim, NE India), Myanmar (Burma), and southern China between 300-1,300 (-1,800) m elevation. An intermediate-growing species, Eria stricta seems to be ideally suited to southeast Queensland conditions. Grow it under about 70% shade in a well-drained medium. During the warmer months provide high humidity, plenty of water and good air circulation. Give it a slightly drier winter rest after flowering, when the plant is not actively growing. Plants will still need less frequent watering as it should not be allowed to remain dry for long periods.
