Two month old gametophytes of P. alcicorne. This image was taken
with a dissecting microscope; the plants are a fraction of
a millimeter across and barely visible to the naked eye.
Mature P. ridleyi gametophyte with a tiny sporophyte (lighter green leaf)
emerging to the right. This culture is about six months old,
and the leaf is 5 mm long.
Various platyceriums that I started from spore, now 2-3 years old and growing in the UConn EEB greenhouses (currently in the care of Sandra Ek). The species are (from left to right): P. stemaria, P. wandae, P. coronarium, P. madagascariense and P. andinum.
