zircote (ziricote) / Cordia dodecandra
Cordia dodecandra of the family Boraginaceae, the borage family
4" x 4" flat cut, 1.5" x 1.5" quartersawn, 3/4" wide end grain, and a 1/4" x 1/4" end grain closeup.
A hard, dark greenish/grayish wood from Central America, mostly from Mexico, this wood frequently has one of the most wildly swirly and billowy grain patterns of any wood. Zircote is related to bocote and some dealers confuse the two, although I have never figured out how since the two really don't look alike at all. Another closely related wood is louro preto / Cordia gerascanthus.
Diffuse porous with large pores that are generally widely spaced and in single rows between rays and have noticeable vasicentric parenchyma. Rays are very strong and are visible to the naked eye, normally spaced and with variable width. Occasional pore multiples, usually radial and in groups of just 2 pores Occasionally will have seemingly marginal parenchyma. The sapwood is sharply demarcated from the heartwood and is rarely attractive.
Common variant name spellings include ziricote and, far less frequently, siricote. Google gives about 40,000 hits for each of zircote and ziricote but only a few hundred for siricote. UPDATE The previous statement was true when I wrote it (about 2002) but now (2013) I find that Google gives only 30,000 hits for zircote and 220,000 for ziricote and 50,000 for siricote so my choice of zircote rather than ziricote has turned out to be a bad one.
