South Asia; they are mainly found in Taiwan.
This plant is propagated by taking cuttings from the lateral shoots and re-planting them elsewhere in the substrate. They should have the bottom leaves removed to reveal an inch of bare stem and carefully placed back into the substrate ensuring that the stem does not get crushed.
This plant displays needle-shaped leaves and is quite demanding of high lighting levels in the aquarium with plenty of nutrients in the water column. They will require a CO2 system to get the best growth and as the stems can be delicate it is best to plant these in a group. This used to be sold as Mayaca sellowiana which caused a lot of confusion but now this name has been dropped.
