When time and funding permit, each flower each plant species will have its own page, and its own PDF, and eventually its own PPT so that professors and students haematosylon plenty of material on Guatemala and Honduras, etc to study. Palo de Brasil is one of the most common brasiletyo in parts of the Motagua desert. Much of the Motagua desert is cacti, Optuntia and organ cacti.

And many areas have Ceiba aesculifolia a relative of Ceiba pentandra. The highway from Guatemala City towards Puerto Barrios also goes through groves of literally thousands of Haematoxylum brasiletto trees, from km ish through kmand even some Palo de Brazil up to the Manzanal area. My interest in this tree is: Although FLAAR is not actively working with geology of the Maya area we are keenly interested since as a student at Harvard I discovered and excavated considerable quanity of jade jewelry in the Tomb of the Jade Jaguar under a pyramid in Tikal three volume report is available as a download, at no cost.

There was also iron pyrite in this tomb: The Motagua deserts is somewhat outside the core Maya areas though Quirigua and Copan are less than 70 miles away. Is Palo de Brasil also a flavoring? Much to my surprise, Palo de Campeche, tinto, is a flavoring edible. This raises the question of to what degree is Palo de Brasil also a potential source of a flavoring. And is the colorant edible, or not?

Lots of research potential here for a thesis or PhD dissertation. Should you spell the genus Haematoxylum or Haematoxylon? Standley and Steyermark Haematoxylum Standley and Steyermark So in the braslletto botany monograph he spells the species name in two different ways.

Should you spell it BraZil or BraSil? It is always spelled by botanists as Palo de Brasil, because this is how hzematoxylon spell that country in Spanish. In English it brasiletyo be with a z, Brazil. There is another tree, Caesalpinia echinata of thepea family, Fabaceae, which produces dye and is called Palo de Brazil. This is the national tree of Brazil. A totally unrelated tree, Dracaena fragansis also called Palo de Brazil.

Dracaena fragans is a common house plant and sold in many nurseries. Dracaena fragans is not a dye plant whatsoever and iconically is native to Haemwtoxylon.

Research and Conservation in Southern Sonora, Mexico

My personal experience with dyewood trees in Guatemala. I learned about Palo de Tinto already ate age 19, when I noticed remains of Brasi,etto campechianum in the royal tomb that I discovered and excavated at Tikal. There are substantial stands of tinto between Lake Yaxha and Lake Sacnab.

FLAAR worked here five seasons and was barsiletto to save this remarkable eco-system by having a national park declared based on our lobbying on behalf of this area with FYDEP and various park services. I then experienced palo de tinto every year that I led tour groups to the Lake Petex Batun area near Sayaxche.


The Arroyo Petex Batun used to be lined with Palo de Tinto now most is illegally cut by local people. Obviously I also saw Palo de Tinto while leading tour groups to Belize. Brasileetto anyone who travels in Belize knows that logwood is the reason the British settled here logwood was the main source of dye for the British wool industry until cheap chemical dyes became available.

It is ironic that I never saw Palo de Campeche in Campeche! Yet in these several decades of experience with Palo de Tinto in swamps and along river shores, I had no idea about the almost identical Haematoxylum species that grows also in Guatemala, but in theory only in the dry deserts, Haematoxylum brasiletto. Earlier I had noticed that Haematoxylum brasiletto was common in deserts of Mexico, such as in Sonora and Oaxaca.

Then in almost half a century after learning about Haematoxylum campechianumI noticed that I had been driving by thousands of Haematoxylum brasiletto trees for decades: Thomas Schrei, a biology student from Universidad del Valle, was on this field trip and he was the one who pointed out the Palo de Brazil.

Location of Haematoxylum brasiletto. Haematoxylum brasiletto probably grows in several areas of Guatemala but where I see it the most often is alongside the highway from Guatemala City towards Puerto Barrios. The trees begin perhaps km. If you had time and haematxoylon to study this plant you could make a more accurate list of its range.

What I notice the most is that for part of this stretch, especially before the areas where Ceiba aesculifolia and cacti are really abundant kmthe Palo de Brazil is the most common tree along the roadside and it is not planted.

Palo de Brasil also continues up in the high hills from El Rancho up towards the start of the pine and oak forests. Obviously the Palo de Brasil is not present any more once the pine and oak forests begin.

Haematoxylum brasiletto flowers for several months. During several months the Palo de Brasil trees along the Carretera al Atlantico were in full flower. What surprised me was that the flowering lasted several months: Since there were thousands of trees I have no realistic way to determine if an individual tree remained in flower the entire time.

Then in late March I noticed still more flowers. When driving down a highway it is not easy to tell the difference between fresh leaves and flowers or dying yellow leaves and flowers. For example, if you had never been to Guatemala before, and you saw the fresh leaf buds of a Ceiba pentandra tree, you would think the trees were brasipetto The fresh leaves are a totally different color than the mature green leaves.

But when we stopped to photograph Ceiba aesculifolia we found a Palo de Brazil still with fresh flowers on it, albeit not totally covered. In many areas the Palo de Brasil trees were in areas so dry that the main plants in the same area were braasiletto.

As mentioned above, this is also a habitat haematoxylin by Ceiba aesculifolia. This ceiba species seems to prefer dry areas, especially dry slopes. Although Ceiba pentandra also grows along the highway through the same Rio Motagua desert area, Ceiba pentandra is more common in haemstoxylon significantly more moist Costa Sur, Alta Haematoxyoln, Izabal, and El Peten.

I do not spend enough time in the Huehuetenango around Santa Ana Huista to notice whether Palo de Brasil brsiletto there also. Standley and Steyermark list it for there Be careful about web sites which confuse Palo de Brazil with Palo de Campeche. Even articles by botanists sometimes confuse these two close relatives.


I presently prefer to keep the two species totally separate: Above is the hwematoxylon and simple way to haematoxylo the situation. However the reality gets more complicated if Palo de Brazil co-inhabits in the Peten.

Is Palo de Brasil, Haematoxylum brasiletto, also native to Peten? Lanza mentions only Palo de Campeche for Tikal ff: Most botanists cite the standard statement: Neither lists Palo de Brasil for Peten.

He writes about the two in the same tone. Lundell makes no mention whatsoever of the unexpected fact that Palo de Brasil is a desert plant. So why is a desert tree in seasonal swamps adjacent to Palo de Campeche? There is zero mention of this in Standley and Steyermark or any other botanical monograph that I can yet find. Now that I understand that possibly Palo de Brazil may be in Peten, I will return when the palo de tinto trees are flowering to see which species is blooming.

Either there are two species, or two varieties of one species. This will be an interesting contribution to the botany of El Peten, Guatemala. Palo de Brasil is also a medicinal plant. The medicinal use of both Palo de Brasil and Palo de Campeche is a whole other study www.

Concluding remarks on Haematoxylum brasiletto. Most books on trees of the Maya area do bgasiletto include or mention Palo de Brasil; most books focus exclusively on Palo de Campeche Trees in the Life of the Braasiletto World is a good example. But the Haematoxylum brasiletto grows precisely in the jade area of the Rio Motagua. There were surely plenty of jadeite miners there two thousand years ago and surely they made haematoxlon of Haematoxylum brasiletto.

The tree makes good charcoal, for example. There is plenty of stone on the surface and road cuts which looks like serpentine in much of the area where you can see Ceiba aesculifolia.

Although the easiest area to see Palo de Brasil in Guatemala are the literally thousands of trees lining the Carretera al Atlantico haemattoxylon km 70 through 90 you can also experiment driving up to Salama Baja Verapaz. That road takes you through more dry areas where you would expect Palo de Brasil. Plus there is less traffic so easier heamatoxylon park along the highway to do your research. Parker covers Haematoxylum brasiletto on her pages Her helpful work baematoxylon a compilation of what is in the multiple volumes of Standley, Steyermark and other botanists.

You can hafmatoxylon all the original info for Palo de Brasil in Standley and Steyermark When possible I prefer to work out in the fields, forests, deserts and mountains. I do not work in herberariums. I love botanical gardens but I prefer to be out in the real actual eco-systems. Thus I spend a lot of time enjoying experiencing the gorgeous display of yellow flowers of Palo de Brasil along two haaematoxylon Introductory bibliography on Haematoxylum brasiletto.
