This beautiful filmy fern is one of the hardier species and grows in nice compact colonies. The rhizomes are rather thick, and the fronds only stand 1-2″ tall. It has a very simple leaf structure, and like most filmys, it likes it shady and wet. I don’t put any filmys in direct light, as their leaves burn easily. They do very well with ambient room light and I wouldn’t suggest putting them within at least two feet of any bright […]
This is an unidentified filmy that is similar in some ways to ekmanni in the simple leaves. The older leaves on this one are small and round, and grow tight to the substrate. It has been growing almost subterranean and seems to benefit from the extra coverage.
A very classical looking fern from Ecuador that happens to be a filmy! It has opaque fronds that have a nice silvery sheen to them. It is one of the few filmys that I’m growing that actually looks like it’s thriving, so perhaps one of the hardier species out there! So far it’s been very slow for me but maybe once better established picks up speed?
by Chuck Nishihira I remember thinking to myself while taking these photos that this was the perfect opportunity to capture both the softness and the details of a filmy fern at the same time. The way that the leaves presented themselves on one plane, all facing in the same direction was perfect. This species was also one of my favorites of the trip. It could be a Hymenophyllum or Trichomanes, but I am unsure of it’s identity. It was small […]
by Chuck Nishihira This beautiful filmy fern is found in Costa Rica and Panama, but it’s distribution may be wider. The thin, membraneous, undulating leaves are fanciful especially when the plant is given time to cover a branch or rock. To achieve the best look, humidity needs to be kept lower than 100%. With filmy ferns it is easy to put them in a sealed container and to forgot about them. But in these situations, the rhizome will leave the substrate (as in the […]
This pristine forest occurs alongside the site locale for Excitobates condor, not 2 km from the Peruvian border. Further up the road and slightly higher than where Excitobates condor is known to occur, there are trails leading off the road that are immediately stunning and rich with plant diversity. The altimeter we took unfortunately died, so the elevation is somewhat undetermined, but it was probably around 2000m. There were an incredible amount of orchids blooming in addition to the abundance of filmy […]
by Chuck Nishihira Just a small, but interesting observation in the filmy fern Trichomanes reptans that I thought I would share. This is the first filmy fern that I have noticed doing this, but from now on I will definitely pay more attention. Initially when a new frond develops in this species, the stalk is rough in texture but the development of hairs is not present (at least to the naked eye). As these stalks start to age, they do […]
This Trichomanes has distinctive black stems, that extend into the individual leaflets of the fern. It is a shiny, beetle like black. Recently spores have appeared in the form on a little lantern hanging off the tips of one frond. This was the first time I had seen this type of structure on a filmy fern. They are rather big and contain hundreds of spores, although when you look through the papery capsule, it looks more like a single black seed.
