　　Triuridaceae , a monocotyledon family , consists of 5
genera and ca.40 species[ 1] .It grows in tropical and sub-
tropical areas.Three species of Triuridaceae were recorded
in Taiwan and Hainan , China[ 2] .Two of them were also
recorded in mainland Hong Kong in 2000[ 3] , but have not
been reported in other areas in China except in Taiwan and
Hainan yet.We found a few individuals of Sciaphila
megastyla Fukuyama et Suzuki on the ground layer of a
bamboo Phyllostachys heterocycla (Carr.)Mitford cv.
Pubescens stand(Fig.1).

It was a mycotrophic herb with purplish colour.It has
slender rhizomes with scales.Fruits in a head of follicles.
Location and habitat: Nankunshan , Longmen
(Guangdong Province), Zhuang Xue-ying NKS2003184;
alt.500 m;on the moss layer of bamboo forest.
Global distribution:Taiwan (alt.300 m), Hong
Kong(alt.800m).It is very restricted and has been on-
ly found in Taiwan and Hong Kong so far.It was catego-
rized as critically endangered (CR) species in Hong
Kong[ 4] .
The population on Nankunshan is very small in situ.
The habitat is frequently disturbed because the bamboo is
usually harvested at an interval of 3 ～ 4 years.So far the
knowledge of this species has not been well known.What
factors are required for its germination and colonization ?
How does it disperse? Further study on the biology and e-
cology of this species is necessary to understand its distri-
bution pattern and ecological importance in the forest e-
cosystem.
