Microgramma - Neotropical snakeferns
Microgramma is a poorly-defined genus that has been known to botanists as early as 1753. They are epithetic ferns that grow on other plants, but not as a parasite. Epiphytes derive moisture and nutrients from the air, rain, water and debris that accumulate around them.
Microgramma are endemic to the Caribbean region, particularly in the Greater Antilles, but also some in South Africa, the western Indian Ocean and one type in a small area of southern Florida.
Microgramma are fast-growing and most have a small frond size and patterned leaves. They are well-suited as terrarium and vivarium plants. They make great additions to damp or wet environments and will climb walls and backgrounds. They also grow well on tree fern rounds and cork branches when misted regularly. Microgramma tolerate traffic over their leaves by small reptiles and amphibians quite well.
