A banana tree grew right outside our casita. I had seen
banana trees every time I’d been to the tropics, but this was my first
opportunity to see one early in the morning. The fruits develop at the top of a
long stalk. A huge flower bud hangs at the opposite end. In the early
morning, one sepal curls up from the bud revealing a layer of flowers. Little
black bees or wasps busily visit the flowers, all in vain from the banana’s
point of view. By afternoon, the sepal and all the flowers are on the ground.
On our cave hike, Edgar mentioned that the banana tree sets fruit only once and
then dies. It also apparently sets fruit only at the top of the floral stalk. All
flowers after that initial fruit development are aborted. It seems like a crazy
amount of wasted effort to produce 2 meters or more of flower stalk with no
additional reproduction. This leads to several questions. If the first fruits
are lost, will subsequent flowers develop into more fruits? Has selective
breeding contributed to this odd flowering strategy? After all, bananas no
longer have viable seeds, so even the process of setting fruit does not result
in reproduction. All our bananas come from cuttings. Are there any wild bananas
anywhere? So many things to ponder.

Another plant in the landscaping was attractive to butterflies. This photo shows a banded peacock butterfly (black, red, and white) on the left and a Julia butterfly (almost entirely orange) on the right.

After breakfast, we met Pablo and Barnaby for a hike through
the rain forest to look at plants that the Maya had used for medicine. We saw
all of the usual, such as tea vine, black poisonwood, gumbo limbo,
give-and-take tree, and Chinese root. Chinese root was used for centuries as a
contraceptive. A U.S. anthropologist called it the most valuable plant of the
last century, according to Pablo. He also said that Chinese root was the origin
of the idea of oral contraception, but I have my doubts.
As
we passed a palm, Pablo spooked two bats. I didn’t see them. He pointed to one
of the leaves and explained how the bats bite only through the veins all the
way around so the leaf ends tip down to create a shelter for the bats. How did
that behavior evolve?
Bats chew part-way through the palm leaf in a circle to create a shelter. The chew marks are the brown spots between the central green and the dusky grey. |
We passed a spectacular example of a sapodilla tree. Back in the day, the
bark of these trees were cut in V’s to release the chicle, which was the original chewing gum,
first used by the ancient Maya. It became commercially important at the
beginning of the 20th century. The sap was collected, boiled, and
exported in blocks. By the 1960’s synthetic chewing gum replaced the natural
chicle for most gum manufacturing.
After completing a fairly level loop along a creek looking
at medicinal plants, we headed upward to the tower. I had already achieved
underwear-to-skin fusion. The sweat poured out of me.

We had chicken fajitas for lunch. The fajitas were exactly
like stew chicken only without bones. The plate a little dish of chicken,
peppers, and onions in red sauce on a plate with three fresh, soft flour
tortillas, and a dollop of refried beans with two corn chips stuck in it. The
table had big bowls of sour cream and pico de gallo.

The alternate selection
was fish and chips. Someone asked for lemon for the fish.The waiter brought a dish of wedges (lemons are green in Belize) carved as snails. We
drank gallons of fruit punch. So delicious!

After lunch, we went to the cacao plantation. We were
pleased to see that Rupert was still working there and would do our tour. The first thing Rupert showed us this year was a hay wagon
full of seedlings. Rupert explained that the root stocks had overgrown the
greenhouse. He gave us his gentle, beautiful smile and admitted that they had
been too ambitious. They now had to plant the root stocks in the field and do
the grafting out there. I felt sorry for the women that do the grafting. It wouldn’t be so bad on a table in the greenhouse, but with the seedlings in the ground, that would be a lot of bending.
Rupert saw the blank looks on the students’ faces, and started explaining about grafting. The root stocks can come from any seed source. They look for vigorous growth, strong anchors, and disease resistance. Then they graft on buds from trees that they know produce good seeds.

I interjected that we raise apples in our area the same way.
The root stock is matched to the soil, and the branches that will bear the
fruit you want are grafted to them. That seemed to make sense to them.
We moved next to the seed fermentation area. Rupert told us
that banana leaves have a white starchy underside that begins the fermentation
process. I didn’t remember that from last year. He removes the banana leaves
after the second day. He didn’t have as many beans fermenting this year. He
invited the students to put their hand in the beans to feel how ware they were.
I pointed out the fruit flies and the larva on the beans when Rupert didn’t say
anything about them.
We moved to the newly-constructed drying tables under
corrugated fiberglass roofs. Rupert showed us how the beans had to be stirred. He had two
tools. One was just a piece of wood about a foot long. The other was a pole
with a board perpendicular to the handle. He used the short piece to pull the
beans away from the edge. He then used the pole to stir the beans and spread
them back into a single layer. Each table can hold one box of beans, which is
2000 pounds. During the peak of the season, they had more than 50,000 pounds of
beans in the facility. To avoid heat stroke during the summer, the workers could only be at the
tables for 20 minutes at a time.

We went inside the building so Rupert could show us the rest
of the processing. The beans have to be sorted by hand. Another improvement
that Rupert suggested when he was at the other facility was in the sorting
process. The table that they were using was rectangular and had 2x4s all around
the edge to keep the beans contained. As the workers sorted the beans, they
would have to lift them over the edge. Rupert redesigned the table as a cross
so four people could work at once. He made a similar table with three arms for
the Belmopan site. The outer end of each arm was open so the beans could slide
into the bag. “It’s nice,” Rupert said, “the ladies can talk or listen to music
while they work.”

His record keeping has revealed that mature cacao trees in
full sun produced the most beans. It stands to reason because all that energy
has to come from photosynthesis, but because cacao naturally grow in the
understory, the general practice was to keep them in the shade. They are now planting the seedlings with
coconut palm. The palms grow quickly to provide shade to the seedlings while
they need it. Their roots grow straight down and don’t compete with the cacao. The
coconuts are economically valuable, but the trees don’t get so large that they shade
the mature cacao.
We went a short way
down the road to where new cacao and coconuts palms
were growing. A crew of workers with machetes and weed whackers was busy clearing
brush nearby.

I saw a cacao seeding with its top bent over and
tied down and asked Rupert about it. He pointed to a branch at the side, which
I had not noticed. The graft was doing well so the top of the root stock had
been bent over to allow the graft to take over as the leader. After it grew a
little more, the top of the root stock would be pruned off.

We had a great time at the cacao plantation. Barnaby was
suitably impressed. It’s possible that other groups will soon be able to have
the Maya Mountain experience.

I had a towel turtle on my bed when we got back to the casita.
