CEIBA

Ceiba pentandra and Ceiba occidentalis

Ceiba pentandra and Ceiba occidentalis of the family Malvaceae (previously was in Bombacaceae). Also called kapok and cotton tree, among some 280 other common names. This is a VERY light, but fairly strong, wood native to to Mexico, Central America and the Caribbean, northern South America, and tropical west Africa. It grows a seed pod that produces a cotton-like substance that is a mix of lignin and cellulose. I was first introduced to it as a Mystery Wood (discussed below) that seemed like a good wood to use for surf-boards because of the combination of strength and light weight.

my samples:
NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K)
colors will vary under other lighting conditions

both sides of a piece of driftwood sent to me for identification. Even though the weight was just over 26 lbs/cuft which is heavy for ceiba, I have concluded none-the-less that it is ceiba. I figure the fact that it was in saltwater for some time may have infused minerals that added to the weight.

both sides of a plank sent to me for identification. Although my fine sanding on the end grain did not expose the kind of noticeable rays I would have expected, nonetheless I still believe that this is Ceiba spp. There is a slight pink tint to these pics that was not in the wood itself.

This plank was my introduction to ceiba. It was sent to me by Gregg Rosner who found it on a beach in Delaware. He was particularly fascinated by it because it is relatively strong and VERY light (18lbs/cuft) and since he makes surfboards, he wanted to know what it was. Some research pretty well convinced me it was Ceiba pentandra but since I had no other samples until recently, I left it on the Mystery Wood page (#166). Having obtained other samples AND having seen the end grain update on them, I am now quite confident that this is ceiba.

Gregg and I both agree that the large swath of discoloration is water stain, not part of the wood figure.

micro-photographs showing the cell structure of Ceiba pentandra. I do not normally include this kind of pic from the Internet on this site but I make an exception here because I'm not finding many web pics of the wood and this cell structure nicely confirms what my own end grain fine sanding shows.
