Further trade and local names: Platymiscium pleiostachyum: cristobal, ñambar (CR); P. yucatanum: chulul, sbinché (MX). Code according to DIN EN 13556: PZXX. Internal code: GRA.
CITES(EU) status of protection. Listed in Annex II(B) (Platymiscium pleiostachyum), or not protected (P. lasiocarpum, P. yucatanum).
Geographic distribution. Mexico and Central America. Platymiscium pleiostachyum: Pacific rim of Central America, from Costa Rica to SW-Mexico; Platymiscium lasiocarpum: Pacific rim of SW-Mexico; Platymiscium yucatanum: Yucatan pensinsula (Belize, Mexico).
Growth rings, colour, grain, etc. Growth ring boundaries distinct, or indistinct or absent (demarcated by fine marginal parenchyma bands visible only with a lens). Heartwood basically brown and purple (dark copper brown, often with a violet hue); with streaks, or without streaks. Sapwood distinct from heartwood colour. Odour indistinct or absent. Wood heavy and hard (0.85–1.10 g/cm3). Interlocked grain present, or absent.
Hardwood vs softwood. Vessels (pores) present (= hardwood).
Vessels (pores). Wood diffuse-porous. Vessels (pores) arranged in no specific pattern; in multiples; commonly in short (2–3 vessels) radial rows. Vessels medium to large (80–150–240 µm); very few (2–4–6). Tyloses absent. Other deposits in heartwood vessels (pores) present, or absent (in case sapwood is mistaken for heartwood).
Axial parenchyma. Axial parenchyma present; banded. Parenchyma bands exclusively marginal (or seemingly marginal); narrow. Other macroscopically visible types of axial parenchyma: aliform and confluent (the latter rare). Aliform parenchyma of the lozenge type.
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure present, or absent (some specimens with, some without storied structure). Tiers regular (horizontal or slightly inclined), or irregular; 4–5 per axial millimetre.
Physical and chemical tests. Heartwood not fluorescent. Water extract fluorescent (P. lasiocarpum: weakly pink to purple; P. yucatanum: bright light blue); colourless to brown. Heartwood extractives not leachable by water. Ethanol extract fluorescent (blue); colourless to brown, or purple (light reddish to purplish brown). Froth test negative. Splinter burns to full ash, or to partial ash; colour of ash bright white. Physical-chemical tests were conducted only with wood of Platymiscium lasiocarpum and P. yucatanum; sufficient heartwood of P. pleiostachyum was not available.
