Lemmaphyllum microphyllum is a widespread species, occurring throughout China, Korea, India, Japan, the Philippines, and Asiatic Islands.  It is a wonderful epiphytic fern, whose fronds only reach about .5 inch.  Fertile fronds will reach about 2″, but are very narrow.  It especially loves to grow on treefern, but cork also works well.  It will grow in a pot so long as the substrate is well drained.  Like many small fern species, it is slow growing (but not difficult).

Available plants are well rooted in 2″ pots.  They will be shipped potted.  The last photo is representative of the size plant you will receive.
