p. 6—“_It spreads like an arm of the sea_.” The great steppe, which extends from the mouth of the Orinoco to the snowy mountains of Merida, from east to west, deflects towards the south in the parallel of 8° north latitude, and occupies the whole space between the eastern declivity of the elevated mountains of New Granada and the Orinoco, which here flows in a northerly direction. That portion of the Llanos, which is watered by the Meta, Vichada, Zama, and Guaviare, connects as it were the valley of the Amazon with that of the Lower Orinoco. The word _Paramo_, which I have frequently employed in this work, signifies in the Spanish colonies all alpine regions which are situated from 11,000 to 14,000 feet above the level of the sea, and whose climate is rude, ungenial, and misty. In the higher Paramos hail and snow fall daily for many hours continuously, and yield a beneficial supply of humidity to the alpine plants, not from the absolute quantity of vapour in the higher strata of the air, but by the frequency of the aqueous deposits occasioned by the rapidly changing currents of air, and the variations of the electric tension. The trees found in these regions are low, and spread out in an umbrella-like form, have gnarled branches, which are constantly covered with fresh and evergreen foliage. They are mostly large-flowering laurel and myrtle-leaved alpine shrubs _Escallonia tubar_, _Escallonia myrtilloides_, _Chuquiraga insignis_, _Araliæ_, _Weinmanniæ_, _Frezieræ_, _Gualtheriæ_, and _Andromeda reticulata_, may be regarded as the representatives of the physiognomy of this vegetation.[CV] To the south of the town of Santa Fé de Bogota lies the celebrated _Paramo de la Suma Paz_, an isolated mountain group, in which, according to Indian legends, great treasures are concealed; and hence issues a small stream or brook, which pours its foaming waters through a remarkable natural bridge in the rocky ravine of Icononzo. In my Latin treatise, _De Distributione geographica Plantarum secundum cœli temperiem et altitudinem montium_, 1817, p. 104, I have thus endeavoured to characterise these Alpine regions: “Altitudine 1700–1900 hexapod: asperriæ solitudines, quæ a colonis hispanis uno nomine _Paramos_ appellantur, tempestatum vicissitudinibus mire obnoxiæ, ad quas solutæ et emollitæ defluunt nives; ventorum flatibus ac nimborum grandinisque jactu tumultuosa regio, quæ æque per diem et per noctes riget, solis nubila et tristi luce fere nunquam calefacta. Habitantur in hac ipsa altitudine sat magnæ civitates, ut Micuipampa Peruvianorum, ubi thermometrum centes. meridie inter 5° et 8°, noctu –0°.4 consistere vidi; Huancavelica, propter cinnabaris venas celebrata, ubi altitudine 1835 hexap. fere totum per annum temperies mensis Martii Parisiis.” Footnote 14:
