UPCOMING MEETING IN DADE COUNTY

Tuesday, March 25, 7:30 p.m. at Fairchild Tropical Garden, 10901 Old Cutler Road.

"Florida's Wetlands" -- Dr. Martin Roessler, environmental consultant.

Dr. Roessler will explain the classification and the function of wetlands, and show examples of the plants used in defining wetland as well as examples of some of the most interesting and beautiful flora of swamps and marshes.

Marty received a Doctorate in Marine Sciences from the University of Miami's Rosenstiel School. After teaching Population Dynamics and Biometry and conducting research on the pink shrimp fishery and ecology of Biscayne Bay, he and several associates from RSMAS formed Tropical BioIndustries, a consulting business in South Florida and the tropics. He has been involved in defining, evaluating and protecting wetlands for many years. Most of us know him best as our field trip leader and the one who knows the plants, as well as the author of the field trip reports in Tillandsia.

Carli Koshal and Lucia Goyen, winners of this year's George Avery Award at the South Florida Regional Science and Engineering Fair, will give a short presentation of their project

We will also have our Annual Meeting with election of the chapter board and vote on a proposed amendment to the bylaws to move the annual meeting to May.

Thanks in advance to refreshment donors: Barbara McAdam, Donna Rich, Patty Harris, George Childs (snacks), Manny Pomares (drinks and ice). New volunteers to bring refreshments, additions to the refreshments and raffle table are also appreciated.

Upcoming meetings. April 22: Dr. Ron Cave, Biological Control of the Mexican Bromeliad Weevil. May 27: Steve Woodmansee, Common South Florida native lawn weeds

NATIVE PLANT DAY at The Deering Estate

CALLING ALL VOLUNTEERS FOR NATIVE PLANT DAY — SUNDAY, MARCH 9

You can see from the enclosed flier and schedule that another great Native Plant Day has been planned by DCFNPS. As you know, this is our chapter's annual public event and most important public outreach. Please encourage your neighbors and coworkers to come (and bring the kids), and post a copy of the flier anywhere you can.

You will certainly want to enjoy some programs and walks, but we also need you to contribute some time as a volunteer. Many of the jobs do not require knowledge of native plants or any special skill.

Please sign up at the February meeting or call Patty Phares (305-255-6404) or Carrie Cleland (305-661-9023) ASAP to tell us how you will help.

GEORGE N. AVERY AWARD FOR OUTSTANDING SCIENCE FAIR PROJECT

Congratulations to Carli Koshal and Lucia Goyen, recipients of this year's George N. Avery Award, presented by the Dade Chapter for outstanding science fair projects at the South Florida Regional Science and Engineering Fair. Their project was titled "Discriminant Analysis of Mitigated vs. Unmitigated Red Mangroves: The Effect of Turbidity on Growth Rates." Carli and Lucia are12th grade students at Dr. Michael M. Krop High School, and their science teacher is Ms. Green. Judges Allyn Golub, Lynka Woodbury and Rita Woodbury selected this project at the science fair on February 11 at Cutler Ridge Mall. The students will present their project to us and receive their awards (certificate and book store gift certificate) at the March meeting.

As you can see from the following project summary, the students demonstrate not only an interest in science and its application in environmental research, but a high degree of scientific expertise.

"Unmitigated areas of Red Mangrove forests present a thriving community. At present these areas have been described as 'healthier' than the mitigated areas. Mangroves planted in mitigated areas grow at a different rate than those that grow naturally. We felt that since unmitigated areas are presumed to be healthier, the red mangroves would grow much faster in this natural environment than in the mitigated areas. Through our research, we found out that wasn't the case. In order to determine what factors contribute to this difference, we tested pH, turbidity and temperature of both mitigated and unmitigated areas of red mangrove populations at Oleta River State Park. Ten red mangroves were selected, each similar in size, from both areas and marked off with string. However, in the mitigated area, mangroves were selected at stratified distances from shore, to determine if distance was a variable. In our analysis, we used a TI graphing calculator in conjunction with a CBL and various probes (pH, turbidity, temperature). To measure the heights of the plants we used a basic tape measure. Readings of pH, turbidity and temperature of the red mangroves in both these areas were taken over the course of a year and the values were plotted. Monthly measurements were taken at comparable times of the day (late afternoon). The measurements show that there was no significant difference between pH and temperature of the areas. However, there was a significant difference between turbidity, as there was higher turbidity in the mitigated areas than the unmitigated areas. This is what we feel contributed to the difference in the high rate of growth in the mitigated area as opposed to the unmitigated area."

WILD DILLY by Roger Hammer

Manilkara jaimiqui subsp. emarginata

by Roger Hammer

One of my favorite native trees of southern Florida is Wild Dilly. Wild trees always exude grand character , with their gnarled trunk, compact canopy, and dull-green oblong leaves. There are usually fruit present and these resemble round, scurfy, brown ornaments tucked among the leaves. When a tree is in flower, the clusters of greenish brown blossoms exude an odd, sweet odor that attracts honeybees.

It is rather unfortunate that Wild Dilly isn't cultivated. Nurserymen claim that it grows too slowly but slow growth can be an attribute in some cases and, as the old saying goes, "good things are worth waiting for." Wild Dilly is a native relative of the more widely known Sapodilla (Manilkara zapota). Like the Sapodilla, the fruit of Wild Dilly are edible when fully ripe and somewhat resemble the flavor of a pear mixed with brown sugar. The white latex extracted from the bark of trees in this genus is harvested for the production of chicle, a principal ingredient in chewing gum. Pick an unripe fruit of either Sapodilla or Wild Dilly, let the milky latex form a small puddle in the palm of your hand, stir it with a finger and, voila, you have chicle. Now try to figure out how to get the gooey stuff off your palm!

The genus name, Manilkara, is taken from manyl-kara, a vernacular name from the Malabar region of southern India for another member of the genus. The species name is from jai-mi-ki, the Taino Indian word for the tree, meaning "Water Crab Spirit," and the subspecies name, emarginata, refers to the notched leaf tip (emarginate).

Getting back to the Taino Indians, it is interesting that many books refer to them as an extinct, aboriginal people from the Greater Antilles. While working on the manuscript for an upcoming book, Florida Keys Wildflowers, I was having difficulty with the name derivation for jaimiqui, and a friend, Dick Wunderlin, suggested that it might possibly be of Indian origin. While surfing the net, I ran across a website for the Taino Indian Tribal Affairs, which started with the headline, "We Are Not Extinct!" I emailed Principal Chief Cacique Pedro Guanikeyu Torres of the Jatibonicu Taino People in Puerto Rico and it was he who enlightened me about the origin of the word jaimiqui. And he even began his reply in the Taino language by wishing me, Tau Ah Taiguey Guaitiao, "Hello and Good Day Friend."

NATIVE PLANTS GREET FAIRCHILD GARDEN VISITORS

As you turn in from Old Cutler Road to enter Fairchild Tropical Garden through our new Jean duPont Shehan Visitor Center, you pass a buffer zone with Matheson Hammock Park. In that zone, we are recreating a hardwood hammock as a transition from Matheson into the Garden, and as a way of presenting the native landscape of South Florida.

The plot we are using lies on the ridge that extends from Miami south to the Deering Estate and eventually to Homestead. The ground was solid rock so deep we had to rent a jackhammer to dig planting holes. We had the chance to start with young plants, so we chose plants of different heights in 1- to 25-gallon containers and also a couple of field-grown trees.

We created a path lined with logs and installed laminated signs so visitors can easily identify and learn the plants. You may recognize the live oak, the gumbo limbo (Bursera simaruba), with its red, peeling bark, and the satin leaf (Chrysophyllum oliviforme) with leaves that are dark green on top and satiny brown underneath. A short-leaf fig (Ficus citrifolia) and three wild tamarinds (Lysiloma latisilaquum) are fast-growing trees that will help shade the area in the near future. Other trees that will grow tall are the paradise tree (Simarouba glauca), the Jamaican dogwood (Piscidia piscipula), two pigeon plums (Coccoloba diversifolia), and the mastic (Sideroxylum foetidissum). You can see a mature specimen of this tree in plot 50 in the Fairchild Garden Arboretum.

As for the understory, the stoppers predominate. Simpsons, Spanish, Red, and White stoppers are mixed in a small group for the wild birds to hide in and feed on. The spicewood (Calyptranthes pallens) can be found nearby with its unfolding pink or pale red young leaves. Wild coffees (Psychotria) are represented with our three native species. You would not mistake the highly glossy leaves with their deeply impressed side veins of the common Psychotria nervosa for the P. ligustrifolia and its glossy dark leaves. P. sulzneri has intensely dark leaves with a distinctive bluish green tinge.

On the female bitterbush (Picramnia pentandra) when it is in season, you can see large clusters of sizable one-seeded berries maturing from reddish to wine red or black. Five Krug's holly (Ilex krugiana) were placed on the east side of the hammock because they are more resistant to cold. A wild lime (Zanthoxylum fagara) stands a short distance from the path, and among its leaves you can observe the larvae of the giant swallowtail.

The marlberry (Ardisia escallonioides) bloomed in early December and was surrounded by its insect pollinators. We also added a couple of crabwood (Gymnanthes lucida), black ironwood (Krugiodendron ferreum),West Indian cherry (Prunus myrtifolia) and the Jamaica Caper (Capparis cynophallophora) for diversity.

Come and see during the years the habit of growth of our native plants at young age, and the wildlife slowly discovering this small but diversify food supply.
