are natives of Europe. It is singular to note that this genus of
conifers extends throughout the entire breadth of the northern hemisphere, Cupressus funebris representing the extreme east in China, and C. macrocarpa the extreme west on the Californian seacoast. The northerly and southerly limits, it is interesting to mark, are, on the contrary, singularly restricted, the most southerly being found in Mexico; the most northerly (C. nutkaensis) in Nootka Sound, and the subject of these remarks (C. torulosa) in Bhotan. The whole of the regions intervening between these extreme lateral points have their cypresses. The European species are C. lusitanica (the cedar of Goa), which inhabits Spain and Portugal; C. sempervirens (the Roman cypress), which is centered chiefly in the southeasterly parts of Europe, extending into Asia Minor. Farther eastward C. torulosa is met with, and the chain is extended eastward by C. funebris, also known as C. pendula. The headquarters of the cypresses are undoubtedly in the extreme west, for here may be found some four or five distinct species, including the well-known C. Lawsoniana, probably the most popular of all coniferæ in gardens, C. Goveniana, C. Macnabiana, C. macrocarpa, and C. nutkaensis (spelt C. nutkanus by the Californian botanists). The eastern representative of the cypresses in the United States of North America is C. thyoides, popularly known as the white cedar. In Mexico three or four species occur, so that the genus in round numbers only contains about a dozen species. The Californian botanist Mr. Sereno Watson takes away Lawson's cypress from Cupressus and puts it in the genus Chamæcyparis, the chief points of distinction being the flattened two-ranked branchlets and the small globose cones maturing the first year.
