ResumoAbstract Abstract Wood anatomy of Carmichaelia australis, Ca. compacta, Ca. corrugata, Ca. monroi, Ca. nana, Ca. odorata, Ca. petriei, Ca. williamsii, Chordospartium muritai, Ch. stevensonii, Corallospartium crassicaule, Notospartium carmichaeliae, N. glabrescens, and N. torulosum is described. These species share vessels with helical thickening and simple perforations; vessels, axial parenchyma, and short rays arranged in storied structure; predominantly fusiform parenchyma; and rays 1–20 cells wide. The ray cells of Carmichaelia and Corallospartium are procumbent, square, or upright, and those of Chordospartium and Notospartium procumbent. The wood of the Carmichaelia complex has well developed xeromorphic features that include narrow diameter and short vessel elements, high numbers of vessels per mm2, and the vessels usually arranged in pronounced diagonal aggregations. Vulnerability and mesomorphy indices are calculated and these support the relationship between species wood anatomy and the xeric habitats they occupy.
