for the Orchid Species Bulletin published by the Orchid
Species Society, which is based in Brisbane,
Queensland in November 2007.
Bear in mind that any cultivation notes refer to the sub-tropical conditions of Southern Queensland, Australia.
Pholidota
chinensis Lindl. was
described by John Lindley in the Journal
of the Horticultural Society,
London
in 1847. Lindley
gave it the specific epithet from the country China
and the Latin suffix -ensis
(origin or place).
Pho.
chinensis is an epiphytic or sometimes lithophytic
plant with pseudobulbs that are borne along a rhizome at 0.5-2.5 cm intervals.
The spindle-shaped to narrowly ovoid-oblong pseudobulbs are 2.5-8 cm long
and 5-23 mm in diameter. Each
pseudobulb bears two stalked obovate-elliptic to sub-oblong leaves at the apex.
Its pleated leaves are 5-22 cm long and 1.5-6 cm across.
Racemes emerge from between the leaves of the newly developing growth.
The pendulous racemes are 6-17 (-38) cm long and bear 10-20 flowers in
two ranks
The
flowers of Pho. chinensis open quickly in succession along a zigzag rachis so
that they are
all open at the same time. The
flowers open widely to about 1.5 cm across and are fragrant or sometimes
scentless. They are uniformly
greenish-white, whitish or white with a creamy-white lip.
Floral bracts next to each flower soon become brown after the flowers
open.
Pho.
chinensis is distributed in southern China
as well as Burma (Myanmar)
and Vietnam. Pho. chinensis grows as a lithophyte or epiphyte in the shade or out
in the open. It inhabits moist to
wet areas from 500-1,700 m altitude. This
species seems to be easy to grow and flower and will often develop into specimen
plants if conditions are to its liking. It
grows well under 60-70% shade with plenty of air movement and regular water
during the growing season. Any
well-drained potting medium can be used, such as a bark-based medium, sphagnum
moss or a perlite/peat moss combination. During
its rest period it can be allowed to become a little drier but plants should not
be allowed to remain dry for long periods. I
suggest a winter minimum of 10 oC.
