The scattered growths were composed of the broomy _Codeso_ and _Retama_. The former (_Adenocarpus frankenoides_), a leguminous plant, showed only dense light-green leaves without flower, and consequently without their heavy, cloying perfume. The woody stem acts in these regions as the _doornboom_ of South Africa, the wild sage of the western prairies, and the _shih_ (_absinthium_) of the Arabian desert. The Arabic _Retama_, or Alpine broom (_Cytisus fragrans_, Lam.; _Cyt. nubigenus_, Decan.; _Spartium nubigenum_, Alton and Von Buch), is said to be peculiar to Tenerife, where it is not found under one vertical mile of height. Some travellers divide it into two species, _Spartium monospermum_ and _S. nubigenum_. The bush, 9 to 10 feet tall by 7 to 15 inches diameter, is easily distinguished from the _Codeso_ by its denser and deeper green. This pretty rounded growth, with its short brown stem throwing out lateral branches which trail on the ground, flavours meat, and might be naturalised in Europe. From June till August it is covered with a profusion of white blossoms, making Las Canadas a Hymettus, an apiarian heaven. It extends as far as the second cone, but there it shrinks to a foot in height. We did not see the tree growing, but we met a party of Chasna men, [Footnote: A romantic tale is told of the origin of Chasna. In 1496, before the wars ended, one Pedro de Bracamonte, a captain under De Lugo, captured a 'belle sauvage,' who made her escape after a few days. He went about continually repeating, 'Vi la flor del valle' (I saw the valley flower), and died after three months. His soldiers buried him and priests said masses for the soul of this 'hot amorist.'] driving asses like onagers, laden with the gummy wood of the _Tea_ or _Tiya_ pine (_P. canariensis_). The valuable material, which resists damp and decay for centuries, and which Decandolle declares would grow in Scotland, is rapidly disappearing from the Pinals. The travellers carried cochineal-seed, for which their village is famous, and a hive which might have been Abyssinian. It was a hollow cylinder of palm-bole, closed with board at either end; in July and August it is carried up the mountain, where the bees cannot destroy the grapes. We searched in vain for M. Broussonet's white violet (_V. teydensis_), [Footnote: Humboldt's five zones of vegetation on the Pike are vines, laurels, pines, broom, and grasses (p. 116). Mr. Addison modifies this scale to vines, laurels, pines and junipers, mountain-brooms and pumice-plains, I should distribute the heights as growing cochineal, potatoes, and cereals, chestnuts, pines, heaths, grasses, and bare rock.] and for the lilac-coloured _Viola cheiranthifolia_, akin to _V. decumbens_.
