White Flowers in Arfak Mountains

When I accompany tourists during their trekking tours in Arfak mountains, I often see various flowers that grow in the jungle. They are so colorful but there are some that are only or mostly white. The one that I saw in the elevation of approximately 2,010 meters above sea level was called Rhododendron Konori. The following photograph is the flower that I mean.

I also saw another species of flower plant that was growing on the trunk of a tree at an elevation of around 1,400 meters. I found some white flowers on the ground below the tree where the orchid grows. They were fragrant but I am not sure whether they fell from the same orchid plant.

 I took the picture of this orchid while I was trekking with four Thai tourists. We watched bowerbird, and saw some birdwing butterflies. If you know its English and Latin name, please, inform me by email to peace4wp@gmail.com
