Wood anatomy of selected Tordyliinae (A-E) and outgroup (F). A Stenosemis angustifolia (TS): exclusively fibrous background tissue composed of moderately thick-walled fibres, wood diffuse-porous, only ray-like structures are bigger cells forming clear uniseriate, radial files. B P. sativa (TS): diffuse-porous wood, vessels disposed in vague radial pattern, axial parenchyma scanty paratracheal, few multiseriate rays. C P. sativa (TLS): uni- and multiseriate rays composed mostly of upright and square cells, simple perforation plates. D P. sativa (TLS): alternate intervessel pitting with pits circular to oval, rounded and with slit-like to narrow lens-like apertures. E Ducrosia anethifolia (TS): background tissue composed of thin-walled fibres, vessels disposed without clear pattern tending to radial. F Pycnocycla nodiflora (TLS): multiseriate and few uniseriate rays, vessels with alternate intervessel pitting and simple perforation plates, scanty paratracheal axial parenchyma in strands (best seen along the first vessel from the left)
