Cupressus
macrocarpa (macrocarpa) is a North American tree that is widely
planted in gardens and as a shelter tree along roads. Seedlings of
this species often appear in the region of these trees, but it is
not clear whether this species is naturalised. This species forms
a broad, dense tree and can be quite large. The adult leaves are
scale-like, overlapping like tiles and oppositely arranged to form
four rows. The leafy branchlets are rounded in cross-section, not
square as in the native montane species,
Diselma archeri and
Microcachrys tetragona. The juvenile leaves are needle-like
and widely spreading. The female cones are more-or-less spherical
and about 1.5-2cm across. The Census of Tasmanian Vascular Plants
lists this species of Hesperocyparus macrocarpa. However, the
most recent reviews of the conifers do not accept this. |
