A rare species of fern at Tanjung Selantai

From my latest fieldwork in Johore, i was given the opportunity to encounter with this rare species of fern at Tanjung Selantai. It belongs to the genus of Breynia. The distribution of this species is very limited in Peninsular Malaysia but is abundantly found at Tanjung Selantai. However, none of the plants found there contained sorus. All the fronds are still young. It is located at a very steep hill with loose soil. It is really a hard climbed and very slippery with lots of ants or termites. I like the view very much.
