Spiranthes
hongkongensis S. Y. Hu & Barretto
Spiranthes hongkongensis prefers damp but well
drained sunny localities. It occurs at both low and high elevations.
Generally the scapes are 15-30 cm. high bearing 10-30 flowers.
In favourable environmental conditions, such as at Kadoorie's
Orchid Haven, and along banks of streams in the mountains north
of Plover Cove Reservoir, specimens with scapes 60 cm. high
bearing 45-60 flowers have been observed.
The flowers of S. hongkongensis wither within 3 days
with the ovaries enlarging very quickly after anthesis. The
lack of viscidium, the pollinia remaining in the cliandrium,
and the rapid enlargement of the ovaries seem to indicate the
apomictic development of the seeds in S. hongkongensis.
