A species of cypress, Cupressus lusitanica, which has been naturalized in the neighbourhood of Cintra is known as the cedar of Goa.
The trees most commonly found are the plane, poplar, maple, walnut, oak, the Cupressus funebris, and various varieties of the genera Pinus, Abies and Larix.
An interesting case has been figured by Masters, in which scales of a cone of Cupressus Lawsoniana bear ovules on the upper surface and stamens on the lower face.
Thuja gigantea of western North America is known in the United States as White (or Yellow) cedar, and the same name is applied to Cupressus Lawsoniana, the Port Orford or Oregon cedar, a native of the north-west States, and one of the most valuable juniper trees of North America.
On the west coast Cupressus Lawsoniana replaces the northern Thuya gigantea, and a laurel (Umbellularia of isolated affinity) forms forests.
Many of the small female flowers borne on shoots with foliage of the Cupressus type consist of spirally disposed and not verticillate scales, e.g.
Thuja occidentalis is the Western or American arbor vitae, the Cupressus Arbor Vitae of old authors.
