Humboldt described the vegetation of the island of Teneriffe [1]. He provided details on its botanical chart, noting the proximity of alpine plants with date trees and Musa at sea level [1]. He also mentioned the plants found at different elevations, including lichens and a violet near the summit of the volcano, with ferns forming a distinct region above arborescent heaths [2, 5].
The passages also describe the vegetation on the western coast of Teneriffe, noting date and cocoa trees, Musa, dragon-trees, vines, orange trees, myrtles, cypress trees, agave, and cactus [3]. An abundance of cryptogamous plants, especially ferns, were observed covering walls [3]. However, the passages do not specify a particular island's vegetation beyond Teneriffe.

From the book
e Alps and on the ridge of the Cordilleras, form close neighbourhood with the plants of the family of the cryptogamia. Tufts of retama, loaded with flowers, adorn the valleys hollowed out by the torrents, and encumbered with the effects of the lateral eruptions. Below the retama, lies the region of ferns, bordered by the tract of the arborescent heaths. Forests of laurel, rhamnus, and arbutus, divide the ericas from the rising grounds planted with vines and fruit trees. A rich carpet of verdure extends from the plain of spartium, and the zone of the alpine plants even to the groups…
everal places by the effect of the small currents of air, which the earth, heated by the sun, began to send towards us. The port of Orotava, its vessels at anchor, the gardens and the vineyards encircling the town, shewed themselves through an opening which seemed to enlarge every instant. From the summit of these solitary regions our eyes wandered over an inhabited world; we enjoyed the striking contrast between the bare sides of the peak, its steep declivities covered with scoriae, its elevated plains destitute of vegetation, and the smiling aspect of the cultured country beneath.…
masses of verdure and of rocks, than the western coast of Teneriffe. The sea-coast is lined with date and cocoa trees. Groups of the musa, as the country rises, form a pleasing contrast with the dragon-tree, the trunks of which have been justly compared to the tortuous form of the serpent. The declivities are covered with vines, which throw their branches over towering poles. Orange trees loaded with flowers, myrtles, and cypress trees encircle the chapels reared to devotion on the isolated hills. The divisions of landed property are marked by hedges formed of the agave and…
teresting expedition to the Antilles and French Guiana, and the descriptions of which he has communicated to us. 1.I.4. ESSAY ON THE GEOGRAPHY OF PLANTS, ACCOMPANIED BY A PHYSICAL TABLE OF THE EQUINOCTIAL REGIONS, FOUNDED ON MEASURES TAKEN FROM THE TENTH DEGREE OF NORTHERN TO THE TENTH DEGREE OF SOUTHERN LATITUDE. I have endeavoured to collect in one point of view the whole of the physical phenomena of that part of the New Continent comprised within the limits of the torrid zone from the level of the Pacific to the highest summit of the Andes; namely, the vegetation,…
ged to the north-east, and in which may be distinguished several systems of volcanic rocks formed at different epochs. The Chahorra, or Montana Colorada, and the Urca, considered in the country as insulated volcanoes, are only little hills abutting on the peak, and masking its pyramidal form. The great volcano, the lateral eruptions of which have given birth to vast promontories, is not however precisely in the centre of the island, and this peculiarity of structure appears the less surprising, if we recollect that, as the learned mineralogist M. Cordier has observed, it is not perhaps…
