This H.mutiflora is collected from South of Thailand. It is different from the Philippines variety in longer internode and the flower is bigger. The flower of this variety is about 1.5 - 2 cm in diameter and the corolla is more yellow than Philippines variety. Some of them, the color is nearly mustard color. It loves the bright light but is not direct sun to give it healthy and bloom. As my experience, I think it is harder to grow than Philippines variety.
