Timber Density: Guyana
Hi Folks,
Ever wonder about timbers from Guyana?
http://web.science.uu.nl/Amazon/Plan...pendix%204.PDF
Ecological Archives E082-037
From these, it looks like the heavyweights are:
Swartzia bannia
Aniba canelilla
Pouteria cladantha
Licania laxiflora
They list Snakewood, Brosimum guianense, as 1.17g/cc but it can get up to about 1.39g/cc. Dense timbers that are not mentioned that grow in Guyana are
Swartzia eriocarpa
Zollernia paraensis
Sloanea nitida
Here's where they grow;

Well, I just received 200 IWCS wood samples from David Persram in Guyana. Here are some pictures. Sorry about the focus issues ...
The first picture is six samples from the genus Licania (Chrysobalanaceae). They had densities around 1.10g/cc but, as you can see, the color and grain are pretty unspectacular. The one I had really wanted was Licania laxiflora but I assume that it is equally as boring.
Next are three samples from the genus Pouteria (Sapotaceae). Like the Licania pieces, the Pouteria pieces are just as featureless and bland. P. guianensis was the heaviest at 1.10g/cc.
Now to the Swartzia pieces. It may be hard to see but S. bannia (1.25g/cc) is in the upper left corner. Staying on the top row but moving to the right, there are S. latifolia (1.21g/cc), S. dipetala (1.17g/cc) and S. benthamiana (not dense). Directly below this is S. oblanceolata, then S. sprucei, probably S. leiocalycina and then some mystery species. None in the bottom row were very dense.
Lastly, I put some heavyweights in one picture. On the left side, from the top moving down are Acacia cambagei (1.33g/cc), Zollernia paraensis (1.29g/cc), Swartzia corrugata (1.32g/cc). Similarly, for the right side; Swartzia bannia (1.25g/cc), Brosimum guianense (1.37g/cc) and Swartzia panacoco (unmarked, 1.30g/cc).
Well, that's it for today's show-and-tell ...
