Cupressus macrocarpa Hartw.
Medium-sized tree (sometimes very large in cultivation), pyramidal at first, with broad crown when mature. Bark thick, reddish brown beneath, often becoming whitish on surface. Adult foliage in dense, dark green masses, aromatic when bruised; branchlets systems not flattened. 1-3-year shoots terete, reddish brown, with lvs appressed except for the cuspidate, pungent, c. 1 mm long apex. Lvs on ultimate twigs uniform, 1-2 mm long, broadly rhombic-ovate, tightly appressed, obtuse or subacute. ♂ strobili 1.5-3 mm long, broad-oblong to subglobose. Mature ♀ cones very shortly stalked or sometimes subsessile, (1.5)-2-3.5 × (1.2)-1.5 × 3.2 cm, subglobose or broadly oblong-ellipsoid, shining brown; scales 8-14; umbo with small, obtuse, crescent-shaped process; seeds usually 10-20 per scale, of irregular shape, with small resinous tubercles.

Notes
editorial
Adams et al. (2009) showed that Cupressusformed two clades: the Old World clade of Cupressuswas sister to Juniperus, whereas the New World clade of Cupressus (Hesperocyparis) included Xanthocyparis vietnamensis and Callitropsis nootkatensis. However, Mao et al. (2010) showed that Cupressus in its broad sense including Xanthocyparis and Callitropsis is monophyletic with weak support. Until resolution of the phylogenetic position of Cupressus is achieved, we take a conservative option and maintain Cupressus in a broad sense, including Callitropsis, Hesperocyparis and Xanthocyparis.
editorial
The protologue is sometimes cited as Vol. 2: 187, but sometimes, it seems, thie description must be regarded as inadequate for publication, and the name is cited as Cupressus macrocarpa Hartw. ex Gordon, Journal of the Horticultural Society of London 4: 296 (1849), wherein the species is more exactly described.
