Distribution: pantropical

Ecology: Wet lowland to open or wooded montane forest, on rock, brick, bark, rotting wood, sandy soil, along streams and waterfalls, 0-1700 m.

Chromosome Number: 10

Notes: Crum and Anderson. The epithet apparently refers to the small point at the end of the leaves. The plants are often sterile but are easily recognized by the contrast of red stems and shiny, yellowish, short-pointed leaves which are concave and have erect, unbordered margins.
