Heart Seed

Here's another heart seed. Love is truly all around us.

This is the papery-winged seed of the African Tulip Tree (Spathodea campanulata). They're blowing all over right now.

Ti napu.

Good Bye, My Gaogao

The Gaogao will die out on Saipan. Gaogao (Erythrina variegata var. orientalis), also known as the Cat's Claw or Coral Tree, is being attacked by the Erythrina gall wasp (Quadrastichus erythrinae) or EGW .


INFECTION AND INFESTATIONThe tiny wasps (females are 1.5mm; males are 1.0mm) lay their eggs in the young leaves and stem tissue of the Gaogao. The eggs then develop into larvae that feed upon the Gaogao as they mature.
The leaves develop damaging galls (abnormal tumors and outgrowths) and fall off. Petioles and shoots swell up and curl growing in an ineffectual manner. These pictures are of the young Gaogao trees planted across the Hyatt Hotel, Garapan on Coral Tree Road. I took these picture on October 2007. Many of the trees there are dying two years later. There is a loss of growth and vigor for the trees, and heavy infestations can cause attacks from other pests and diseases more easily. Ultimately, the trees will die. I started noticing familiar and well established Gaogao trees on my outings and hikes. Check out this leafless and lifeless giant. I found this dead tree at the Laderan Tanke Trail this year. March was supposed to be the height of this tree's blooming season. Notice the rotting bark on the trunk.The Eythrina gall wasp was first described (Kim et al. 2004) from specimens infecting trees in Singapore, Mauritius, and Reunion. The next two years saw its spread to China, India, Taiwan, Philippines, Florida, American Samoa, Hawai’i and Guam. EGW started showing up on Saipan in 2007. It is uncertain if the wasps originated from Africa according to the discoverers. Our agriculturists believe that Saipan’s pests came from Tinian and Rota. Here is a picture of the wasp's life cycle from Fleming Arboretum:



Former Glory
The Gaogao is one of my favorite native trees in the CNMI. It is also for the native fauna (birds, Marianas Fruit Bat, insects, etc.). It is a tree that can match the beauty and flamboyance of the Flame Tree as I try to convince people to plant more natives. Traditional medicine also utilizes the Gaogao.

A hike through the Laderan Tanke' Trail this past March yielded some evidence in the leaf litter that some Gaogao trees survived to flower another season.


Crafters here also bead together the purplish seeds for necklaces and Bojogo dolls that are marketed to the tourists. Here, the seeds represent the doll's hands and feet.

Erythrina trees have a variety of functions in other locations as well. The flowering of the red flowers (erythros is Latin for red) is highly associated with farming and fishing activities in Taiwan. The flowering is a working calendar by tribal peoples as sign of the arrival of spring. It is a sign for the coastal tribes to start catching flying fish, and for the Puyama tribe to plant sweet potatoes. In American Samoa, the blooming trees signal the return of whales in their waters.

The following pictures are from July 2006 at the American Memorial Park, Garapan.

These are from February 2008 in San Roque at the Park Hotel Parking lot. It was one of the better sites to watch the birds that came out to celebrate the blooming of the Gaogao.

Can you see the Egigi or Cardinal honeyeater (Myzomela cardinalis saffordi) in the picture below? This endemic subspecies of the honeyeaters found in Micronesia is a fervent nectar eater and loves the Gaogao.

There's the Egigi! The Nosa or Bridled white-eye (Zosterops conspicillatus) is usually seen as a hungry insectivore foraging on leaves and twigs. It does not shy away from the delicious nectar brought on by the Gaogao blooms though. Can you see the tiny fella in the picture below? I must have counted more than 20 birds in these trees. I am sorry for not having a camera with a nice zoom feature.

This tree is probably more than 100 ft (30.48m) tall and found in Chalan Kanoa during the 2009 bloom also in February.

These are what the seeds look like as well as the seed pod and flower bracts. These are from the trees of the CNMI Retirement Building, Capitol Hill from February of last year.

In Hawai’i, the wiliwili (Erythrina sandwicensis) another species of Gaogao is a revered native and indigenous tree. It is used as an ornamental as well as for functional landscaping (windbreaks, hedges, erosion control). The soft mature wood has been used for booms and floats for single hull canoes and long surfboards. The seeds are collected and beaded for leis that can fetch up to $500 each. Since the EGW infestation, Hawai’i has tried physical (cutting down or remove and replace), chemical and biological controls to save the wiliwili. . Some people feel that the best way to preserve the wiliwili is to collect and bank as many seeds as they can before they are all gone.

The following images of the wiliwili is from Forest and Kim Starr. The Maui based biologists work for the Univesity of Hawai'i and have an environmental consulting firm for conservation involved in protecting the wiliwili.

The beautiful wiliwili bloom.APPARENT DAMAGE

It is also unfortunate that some people in agriculture and forestry limited the planting of the Gaogao in recent years. They believed that more Gaogao trees would help host and propagate more fruit piercing moths that could eventually infect fruit crops. There is a delicate balance to nature especially in our small islands that is why we should be careful as to what is introduced in our land and waters.

We will eventually see all of the Gaogao trees die in Saipan. An article in the Marianas Variety reports that our entomologists and agriculturists will let them all die thinking that their extinction will lead to the starvation and the eventual elimination of the EGW and fruit piercing moths. In a few years, the Gaogao can be reintroduced free of pests.

This well established tree in Middle Road, San Jose across the Taste of India Restaurant withered and died this year.

I usually look forward to the Gaogao blooms in March. I enjoy watching the full crown of the trees in red and the creatures that come out for the food providing flowers. I also try to show the blooms to as many people as I can so that they are aware of the importance of CNMI’s native trees. Many of the trees that I visit for the flowers are now dead. I will miss the Gaogao sorely.
My heart breaks for you
I will miss seeing you bloom
Good bye, my Gaogao

Ti napu.

Wild Passion in the Jungle

Bubbles Bev (or is it Mae now) told me that a title makes or breaks a story. So, I hope I hooked you into reading my story. Passion, fervor, ardor, obsession, infatuation, excitement, enthusiasm, zeal, craze: these are words that are enough get us all hot-blooded. We all need a little passion in our lives right? But, I hope you laugh a little when I slowly transition into talking about plants and flowers in my story.

Flowers fascinate me, but not just because of their beauty. Why are there flowers anyway? Flowers are well, basically sex organs. They are made for the purpose of continuing the line of the plants that make them. Their form, color, scent, feel, arrangement, etc. all point to the act of pollination. Flowers are either male, or female, but more often, they have both male and female parts.

When was the last time you received flowers? Sent flowers? People have tagged different meanings to types of flowers or the color of flowers, but the reason for the busiest day in the flower shop points to passion. The last time I sent a dozen roses to some one, the recipient said, “I loved them, sweetie! I thought I just wanted you to save the money for dinner and a movie, but these are breathtaking! I’m so glad you got them.” So in conclusion, no matter what they say: Flowers = Chichiiing! Hehehe! I jest.

I’d like to introduce you to the Passifloraceae family of plants. Passiflora means “passion flower” and we have two kinds on Saipan that were introduced possibly by accident. Their flowers are so attractively intricate and it’s hard to imagine that some people don’t notice them. Well ok, one is really small and cryptic. The PIER (Pacific Island Ecosystems at Risk) lists them as an invasive threat to our islands (especially to the Northern Mariana Islands) since their vines can cover other plants. When the conquistadores first saw these flowers in Central America, they named them after their symbolic passion for Christ. These particulars make the passion flower very fascinating to me.

The Fetid Passionflower (Passiflora foetida) is the larger of the two flowers. Look at how beautiful they are in the pictures below. But why is it called “fetid”? Some publications say that the plant has a stinking smell to it. I’ve never noticed their alleged stinkiness. The white and purple flowers are about 5 cm, and the 2 cm fruits are either pale yellow, orange yellow or red. The pulp and crunchy seeds offer a little and often unsatisfying snack, but they really resemble the taste of the more bigger commercial varieties of passion fruits. The climbing vine is hairy with lobed leaves and you’ll see them in trails, open lots and on wire fences. The pictures are from Coral Ocean Point, and the Costco lot. The beautiful Chamorro name for this flower is Kinahulo’ atdao, which means sunrise. I first got introduced to this particular Passiflora while growing up in the town of Canlubang in Laguna, Philippines. My friend Mark A. started eating them off the vines and said that they were called Kurumpot. What an ugly sounding name for such a pretty flower, I thought to myself!

Kinahulo’ atdao (sunrise): Does the name fit the flower?

That fruit's almost ready to eat.

Those are immature fruits in those pom poms. Pom Pom is also the Pohnapeian name of this fruit. The corky or wild passion fruit (Passiflora suberosa), like P. foetida, is also considered a weed vine. The small dark purple fruit is food only for wildlife but the 1.5 cm flower is just as intricate compared to the rest of the family. It is easy to see why people don’t notice them though, since they are very inconspicuous. Suberosa means “wood cork” and refers to the wood-like quality of the very mature vines. The fruit pictures I took at the Marpi area and the flowers pictures are from the Hyatt Regency garden and San Antonio Beach.

A ripe fruit for the birds. Some immature fruits on a creeping vine.The last story I would like to share with you involves a medical doctor that I knew on Guam who fell in love with the Indonesian passion fruit while vacationing in Bali. He loved the purple passion fruit or Siuh (Passiflora endulis. F. Endulis), but knew that customs would not allow him to bring any to Guam. So Dr. L decided to enjoy and eat as many as he can the evening before flying home. He made sure that he swallowed enough seeds whole. Lo and behold, a few months later he had a trellis with a beautiful vine full of immature passion fruits! Kind of a funny story, and I am sure that Dr. L's digestive system "cleaned" the seeds out, but this is a good opportunity to remind you that bringing plants or fruits from other places can have a devastating impact on our island’s unique ecosystem. Introduced species can become invasive and compete with the native flora and may even bring diseases or pests that can ravage the unwitting existing system. We must do what we can to protect an environment that can't do it by itself.

Thank you for letting me share.
