Gelsemium elegans(鈎吻/胡蔓藤/斷腸草 ● Graceful jesamine)

Gelsemium elegans is a climber widely distributed in Hong Kong. Large populations could be found in thickens or anywhere where sunlight is ample. The plant is very poisonous and many people might have heard of its Chinese common name 斷腸草. The name describes the pain people feel after an intake of the plant which is a fatal stomach ache. The plant bears large amount of yellowish flowers in summer or autumn. In Sai Kung, I have seen a population covering up a whole valley forming a very striking view full of yellowish flowers. The large amounts of capsules containing winged seeds are formed in the winter, using anemochory as a seed dispersal method. The first six photos are taken in different parts of the Ti Mo Shan(大帽山)area in the NT, the last three pictures are taken in Sai Kung.
