Nomenclature. Family: FABACEAE-FABOIDEAE. Further trade and local names: campinzerán, campinchirán, tampinzerán (MX), camotillo rosewood (US). Code according to DIN EN 13556: none.
CITES(EU) status of protection. Listed in Annex II(B) (D. congestiflora is also on the list of Mexico’s endangered species (Norma Oficial Mexicana NOM-059-SEMARNAT-2010), which means that their management and exploitation are regulated by the provisions of the "Ley General de Vida Silvestre" (LGVS, 2000) (General Wildlife Act)).
Similar timbers. Dalbergia species with a characteristic purplish brown heartwood and a diffuse pore distribution.
Geographic distribution. Mexico and Central America. To date only known from south-western México; possibly also present in Guatemala and El Salvador.
Growth rings, colour, grain, etc. Growth ring boundaries indistinct or absent. The regularly ocurring dark coloured zones on transverse sections (colour streaks on longitudinal faces) shall not interpreted as growth increments. Heartwood basically brown, purple; with streaks. Sapwood distinct from heartwood colour (cream to yellowish white). The dark violett fiber tissue alternating with light colored parenchyma bands gives the wood an attraktive curly figure on tangential surfaces. Odour indistinct or absent. Wood heavy and hard (0.94–1.06–1.23 g/cm3). Interlocked grain absent (but the grain is frequently very irregular).
Hardwood vs softwood. Vessels (pores) present (= hardwood).
Vessels (pores). Wood diffuse-porous. Vessels (pores) in multiples; commonly in short (2–3 vessels) radial rows and in radial rows of 4 or more (few). Vessels of rather different size and unevenly distributed over the cross section. Vessels medium to large (100–200 (-240) µm); few (5–7–10). Tyloses absent. Other deposits in heartwood vessels (pores) present (rosé to brownish violet).
Axial parenchyma. Axial parenchyma present; banded and not banded. Parenchyma bands not (only) marginal; narrow to wide; much wider than rays. Other macroscopically visible types of axial parenchyma: diffuse-in-aggregates and vasicentric.
Rays. Rays narrow. Large rays commonly less than 1 mm high.
Storied structure. Storied structure present. Tiers regular (horizontal or slightly inclined); 5–6 per axial millimetre.
Physical and chemical tests. Heartwood not fluorescent. Water extract not fluorescent; colour shade of water extract light purple. Heartwood extractives slightly leaching out when in contact with water, or not leachable by water. Ethanol extract weakly blue fluorescent; colour shade of ethanol extract purple. Splinter burns to full ash; colour of ash bright white.
Additional information. • Transverse section + wood surface. Transverse section ca. 10x. Tangential (centre) and radial (right) surface, natural size.
