Aeschynanthus in Doi Inthanon

I went to Northern Thailand in February and visited Doi Inthanon (in Thai "ดอยอินทนนท์") which is the highest mountain of Thailand. The weather was gorgeous because it was the dry season and the sky was clear and blue like the sapphire in the mountain. And because it's dry season, it's not a right time to visit Doi Inthanon if you are looking for Gesneriads. I only saw a species of Aeschynanthus in the mossy forest. This is one of most popular national parks in Thailand and it is full of biologic treasures.
