Megaphylls are Pteridophytes or ferns and their allies in
the plant family. Its foliage leaf has parallel vascular bundles through the
lamina. The megaphylls of ferns are large pinnate leaves called fronds. It has
neither flowers nor seeds. Its reproductive structure is composed of spores or
microorganisms produced through a process called meiosis in sporangia or
sporangial clusters. Spores are released from the parent plant to produce
free-living gametophytes. These are generally carried into the air or by ants
and thus produce new plants. This type of Megaphyll originates with a very tiny
sprout and eventually grows into a large fern with leaves measuring more than
one meter.

This specimen (figure 1 & 2) is one of my original collections. This
was originally planted in 1981 as a landscaping plant in the grounds of The
Church of Jesus Christ of Latter-Day Saints in Surigao City, Philippines.
Generally ferns do not thrive under the heat of the sun. Through the years this
plant had not grown beautifully because it was planted in an area under direct
sunlight. One summer I found it abandoned with all leaves and aerial roots dried,
and without any sign of life. It has no penetrating roots and it was so easy to
pluck its body from the ground where it originally stood. I brought it home
hoping to save it. I planted it first on a pot under the shade of a tree. With
continued caring the plant begun to show a few fronds and eventually survived.
Its black dried aerial roots accumulated through the years measuring about 2
feet remained to look ugly although the fern had already produced large leaves.
So I decided to reduce the length of the body only to find out that within was
kind of a very hard trunk which needed to be cut by a saw. After cutting I noticed that the plant seemed
to shrivel. I thought that the trunk must have been part of its source of life.
Yet I tried to care and preserve it. It was only months after that it
recovered. I then transferred it in a fabricated concrete stand. After fifteen
years at home or a total of more than 33 years of its known existence (It was
already fully grown when planted in 1981) it has survived. Another variety of
fern binds its aerial roots.

The small Megaphylls which I collected sprouting on trunks
of Cycas Revoluta palms the same year, which I understand to be products of
that original specimen, are now grown for fifteen years (see figures 3, 4,
5 & 6). Since I have these plants, more and more had grown in my backyard and they
usually sprout on the base of my bonsai trees (see figures 7, 8 & 9). Many
times I have to throw them as grass, because I only have a very small space to
accommodate them. Some of them I left to
grow on the base of my Cycas Revoluta Bonsai specimens (se figures 10, 11 & 12).

This Megaphyll variety is very good as house plant only
that it would require care because it usually is used as havens for ants.
However, it can easily be controlled by insect sprays. Its beautiful large green leaves are really
very ideal and attractive inside the home or office.
