Towards the centre the almost treeless plain presents a monotonous aspect, broken only by a few rocky elevations that rise abruptly from the black soil.
This phenomenon occurs among species found at high elevations, among others found in arid or desert regions, and in some cases in the female sex only, the male being winged and the female wingless.
The more rugged districts and higher elevations are clad with such tropical forest trees as ebony, Spanish cedar, sandalwood, rosewood and mahogany.

A relief map of Brazil shows two very irregular divisions of surface: the great river basins, or plains, of the Amazon-Tocantins and La Plata, which are practically connected by low elevations in Bolivia, and a huge, shapeless mass of highlands filling the eastern projection of the continent and extending southward to the plains of Rio Grande do Sul and westward to the Bolivian frontier.
A thick sandstone sheet once covered the greater part if not all of it, remains of which are found on the elevated chapadas of the interior and on isolated elevations extending across the republic toward its western frontier.
These chapadas and elevations, which are usually described as mountain ranges, are capped by horizontal strata of sandstone and show the original surface, which has been worn away by the rivers, leaving here and there broad flat-topped ridges between river basins and narrower ranges of hills between river courses.
The southern margin of this plateau breaks down abruptly toward the south and overlooks the Parana and Paraguay basins from elevations of 2600 to 3000 ft.

Coffee-planting is a new industry on the Pacific slope of the Sierra Madre at elevations of 2000 to 4000 ft., and has met with considerable success.
Among them may be mentioned the aperea or restless cavy (C. porcellus or C. aperea) of Brazil; the Bolivian C. boliviensis, found at great elevations in the Andes; the Brazilian rock-cavy (C. rupestris), characterized by its short blunt claws; and the Peruvian C. cutleri.
The lower valleys produce dates in abundance, and at higher elevations wheat, barley, millets and excellent fruit are grown, while juniper forests are said to cover the mountain slopes.
At higher elevations the rainfall is no doubt heavier; Manzoni mentions that at Sana there was constant rain throughout August and September 1878, and that the thermometer during August did not reach 65°.
Among the first wild shrubs and trees that are met with are the chilca (Baccharis Feuillei), with a pretty yellow flower, the Mutisia acuminata, with beautiful red and orange flowers, several species of Senecio, calceolarias, the Schinus molle, with its graceful branches and bunches of red berries, and at higher elevations the lambras (Alnus acuminata), the sauco (Sambucus peruviana), the quenuar (Buddleia incana), and the Polylepis racemosa.

This species inhabits forests, and ascends hills to considerable elevations; it is shy and timid, but easily tamed even when adult.
A branch of the Sierra Madre extends northward from the vicinity of Salinas, but its elevations are low.
The general conclusion would appear to be that, while as seen from the earth's surface much of the light from the sky is due to comparatively gross suspended matter, yet an appreciable proportion is attributable to the molecules of air themselves, and that at high elevations where the blue is purer, the latter part may become predominant.
This elevated region is known as the plateau of Matto Grosso, and its elevations so far as known rarely exceed 3000 ft.
The lowland elevations in this part of the state range from 300 to 400 ft.
Past elevations of land, however (and doubtless equally great subsidences) have taken place in South America since the Eocene, and the conclusion that extensive areas of land have subsided in the Indian Ocean has long been based on a somewhat similar distribution of giant tortoises in the Mascarene region.
On the higher elevations it is generally stony and sterile, but in the valleys and on many of the lower hills, where it consists largely of clay and sand, it is quite productive.
Mountains of Europe and North America they grow only at moderate elevations, and none approach the arctic circle.
High elevations reproduce the physical conditions of high latitudes.
Attempts have been made to bring it into more general use, but without success; and it is only in particular circumstances that navigation, with the aid either of locks or inclined planes to surmount the elevations, will not present a more convenient medium for an extended trade."
On the one hand he may make the line follow the natural inequalities of the ground as nearly as may be, avoiding the elevations and depressions by curves; or on the other he may aim at making it as nearly straight and level as possible by taking it through the elevations in cuttings or tunnels and across the depressions on embankments or bridges.

In general the main elevations of the two ranges form pairs lying opposite one another; the forms of both ranges are monotonous, but the colouring is splendid, especially when viewed from a distance; when seen close at hand only a few valleys with perennial streams offer pictures of landscape beauty, their rich green contrasting pleasantly with the bare brown and yellow mountain sides.
Several of the lesser elevations near the lake are especially famous as view-points, such as Castle Head, Walla Crag, Ladder Brow and Cat Bells.
There is a wide variation of climate for so small a territory, the higher elevations of the Sierra de Ajusco being cold and humid (the Mexican Central crosses the range at an elevation of 9974 ft.); the lower spurs mild, temperate and healthy, the lower valleys subtropical, hot and unhealthy.
The Scottish shore, however, is not continuously flat, and such elevations as Criffell (1866 ft.), Bengairn (1250) and Cairnharrow (1497), above Wigtown Bay, rise close to it.
A distinct connexion between the flora of the peninsula and Ceylon and that of eastern tropical Africa is observable not only in the great similarity of many of the more truly tropical forms, and the identity of families and genera found in both regions, but in a more remarkable manner in the likeness of the mountain flora of this part of Africa to that of the peninsula, in which several species occur believed to be identical with Abyssinian forms. This connexion is further established by the absence from both areas of oaks, conifers and cycads, which, as regards the first two families, is a remarkable feature of the flora of the peninsula and Ceylon, as the mountains rise to elevations in which both of them are abundant to the north and east.
