Nomenclature etc. RUTACEAE. Syn. Fagara chiloperone Engl. ex Chod. & Hassl. Trade and local names: mamica-de-porco, mamicão (BR); bois piquant, lépiné (GF); bois chandelle blanc (HT); ayúa amarilla (cAm). Not protected under CITES regulations.
Tree. Geographic distribution: Mexico and Central America, Caribbean, tropical South America, southern Brazil.
General. Growth ring boundaries distinct. Delimited by a 1–2 seriate marginal parenchyma band. Heartwood basically yellow. Sapwood colour similar to heartwood colour.
Vessels. Wood diffuse porous. Vessels in multiples, commonly in short (2–3 vessels) radial rows. Average tangential vessel diameter 26–64–100 µm. Average number of vessels/mm² 35–51–66. Perforation plates simple. Intervessel pits alternate, average diameter (vertical) 4–6 µm. Vessel-ray pits with distinct borders, similar to intervessel pits. Other deposits present (brown).
Tracheids and fibres. Fibres very thin-walled to of medium wall thickness. Fibre pits mainly restricted to radial walls, simple to minutely bordered. Fibres non-septate.
Axial parenchyma. Axial parenchyma present, banded. Bands marginal (or seemingly marginal). Bands fine. Axial parenchyma apotracheal, or paratracheal. Apotracheal axial parenchyma diffuse-in-aggregates. Paratracheal axial parenchyma scanty. Axial parenchyma as strands. Average number of cells per strand: 3–5.
Rays. Rays 5–7–8 per tangential mm, multiseriate, (1–)2–3 cells wide. Height of large rays up to 500 µm. Rays composed of a single cell type (homocellular), or two or more cell types (heterocellular) (only few rays heterocellular); homocellular ray cells procumbent. Heterocellular rays with square and upright cells restricted to marginal rows, mostly 1 marginal row of upright or square cells.
Storied structures. Storied structure absent.
Secretory structures. Intercellular canals present, traumatic origin, oriented axially, axial intercellular canals in long tangential lines or in short tangential lines. Tangential rows of traumatic resin canals at irregular intervals.
Mineral inclusions. Crystals present, druses and in other forms, located in ray cells and axial parenchyma cells. Crystal-containing ray cells procumbent. Crystals in procumbent ray cells not in radial alignment. Crystal-containing axial parenchyma cells not chambered. Number of crystals per cell or chamber one. Silica not observed.
