Opisthotropis andersonii is not only endemic to China, but also a near-endemic to Hong Kong with a narrow geographical distribution. It has not been assessed by IUCN Redlist but no significant threat is posed to the species at the moment. It is non-venomous and very docile which rarely attempts to bite. It is commonly found in lowland streams in Hong Kong. It is not surprising to see two or more individuals in a night within the same stream.
Anisopappus chinensis (Asteraceae) is a Chinese endemic which is mainly ranged from South China. It is also the only species from the genus distributed in China. It has a prolonged flowering season where flowers were seen from April to October. It explicitly inhabits dry grassy slope in Hong Kong. Though it is said to be a common species, I only had a few encounter of it. However, hiking on dry grassy slope in high summer is something not very pleasant.
